PURPOSE OF DOCUMENT
The goal of this document is to provide a hardware designer with enough information to use the Itron
Riva Dev Mini board as a processing engine for assorted types of projects. It will cover the hardware
necessary, at a high level, to guide a designer to the point where they can bring Linux up on the
platform.
This document is intended to show the user how to interface the Itron Riva Dev Mini to a product
based on the Muse platform. However, there will not be a comprehensive definition of how to use
each type of GPIO to interface to assorted devices. This will have to be obtained through the A8
datasheet. Some examples will be given but most of the time only the parameters of the pin will be
defined and its usage left up to the end product designer to reconfigure them as necessary. You may
contact Itron for specific interface assistance.
Building Linux will also be covered in a separate document.
This document is not intended to inform the user how to use Linux or any subset of Linux commands.
The coverage of Linux will only cover booting to a kernel prompt. This document is not intended to
be a detailed usage guide to Linux or to the intricacies of the additions that Itron has made to Linux
through its extensive IP library. These details are covered in separate documents.
This document is also will not cover Muse additions to the Linux Operating System or the Itron Over
the Air protocols or how to use them. Contact Itron for specific assistance in these areas.

ITRON RIVA DEV MINI INTRODUCTION
This section describes, at a very high level, the nature of the Itron Riva Dev Mini which is based on
the Itron iSOM and includes ACT RF functionality to support the 870 MHz and the 920 MHz bands
used for the proprietary Openway network. The RF section connects to an antenna via a UF.L
connector4.
The Itron Riva Dev Mini has one mini-USB connector. Power can be derived from the external host
when the board is operating as a USB device. Power can be provided to a device when the board is
operating as a host. This is basic OTG operation but not certified as OTG by the USB group.
The Mini DK does NOT directly support Ethernet. An Ethernet port can be created by using a USB-toEthernet adapter.
The Itron Riva Dev Mini does NOT support EMMC or other external memory. It is possible to breakout J4 to provide a second USB port that can use USB based external memory such as a hard drive or
a thumb drive.
A 40 pin expansion connector is provided to bring control and communications off the board. The
pinout is shown below. This connector allows use of a standard ribbon cable to extend the signals to
another board.
Only specified antennas may be used for integration of the OEM module to comply with emission limits! Please
refer to the antenna tables in this document. RF Cable type and purchasing information is provided later in the
document.

MAJOR COMPONENTS
The following sections will list the major components on the Itron Riva Dev Mini and briefly describe
them. Datasheets are available for more detailed information.
Caution!! Only specified antennas listed in this document may be used for integration of the OEM
module to comply with FCC emission limits! Please refer to the antenna tables in this document.
Antenna and RF Cable type and purchasing information are provided later in the document.
CPU BRIEF
The Muse Platform contains a TI AM335X ARM Cortex Microprocessor. The processor contains a
number of internal peripherals such as UARTs, SPI, I2C, USB, MMC, RTC and others. It also contains
an internal boot ROM and internal RAM. The ROM and RAM are mostly used during the boot-up
process and during security operations.
CLOCKING
A 26MHz clock crystal is used to clock the AM335X. This is internally changed to 450 MHz using an
internal PLL through Firmware. Other speeds can be selected depending on user requirements.
FLASH AND RAM BRIEF
The system contains a Micron technologies MT29C2G24MAABAHAMD-5IT chip in a 130 ball package
combining both FLASH and RAM on single chip. The Itron PN is 570725-003. This is a 2Gb NAND
(x16bit) + 1Gb (x16bit) LPDDR.

RTC BRIEF
The module contains a NXP PCF85363A RTC CHIP. It is a tiny Real-Time Clock/calendar with 64-byte
RAM, alarm function, battery switch over and I2C-bus.
PIC BRIEF
The module contains a Microchip PIC16LF1823, or PIC16LF1823 microprocessor to serve as the
power rail control and to provide some system support features.
The PIC provides
1. Power Rail control
2. PON timing
3. Reset capability for the A8
4. EEPROM and some configuration storage.
PMIC BRIEF
The TI TPS650250 PMIC provides 3.3VDC, 1.8VDC and 1.1VDC regulators to supply the requirements
for the A8, RAM, FLASH and other components.
The PMIC also provides two LDO regulators. One provides 3.3VDC to the PIC and the other provides
3.3VDC to the Real Time Clock chip 5 . The two LDO enables are hard wired to a MIC826 voltage
monitor chip and come on as soon as 5 VDC is applied to the module. The PIC will then sequence the
power rails to the A8 and other circuitry.
As of the writing of this document the RTC chip was being changed. The original chip was an AM1805. I do not
know what the new chip is at this time.

ITRON RIVA DEV MINI POWER HANDLING
POWER INPUT
The Mini requires a single +5 VDC supply. The input voltage should be within 4.75 VDC and 5.25 VDC.
+5 VDC SUPPLY
The Itron Riva Dev Mini requires an input power supply of +5 VDC. This can be supplied through the
mini-USB connector or through the expansion connector. The +5.0 VDC supply derives from one of
two sources: U57, the mini-USB connector or from the expansion header pins 1 and 2. In either case
this board can consume a peak of about 6 watts during full power transmissions.
+5 VDC from USB
When the Itron Riva Dev Mini is powered through the mini-usb connector it will provide +5 VDC
power to the expansion connector pins 1 and 2. There is a circuit to limit the inrush current to prevent
the host from triggering an over-current error. Once the initial period of current limiting ends the
TPS2151 will allow up to 1.6 amps to flow from the USB Host. Note it is up the system firmware to
provide the configuration and protocol operations to request the maximum required current from
the host port. Careful attention to this detail must be followed for adding external circuitry.
+5 VDC from Expansion Header
If the mini-USB port is not used as a power source +5 VDC may be supplied through the expansion
connector pins 1 and 2. Currently, for the first prototype run, this will not provide power to the miniUSB port. It should be possible to put a diode where R21 is to allow powering the mini-usb from the
expansion +5 VDC input.
POWER OUTPUT
+5 VDC to USB
When powered from the USB connector the current limited +5 VDC is routed to the Expansion header
to provide power for additional circuitry.
+3.3 VDC SUPPLY TO EXPANSION CONNECTOR (3V3_EXP)
There is a 3.3 VDC regulator connected to the +5 VDC signal to create an expansion power supply for
use by the user. This rail is gated by a signal from the iSOM which tells the system that the iSOM is
powered on and ready. This supply rail is limited to 250ma.
USER POWER SUPPLY WARNING
When adding hardware to the interface connector it may be required to create additional power
supply rails or higher current supplies. It is important to not connect any of these voltages to the
Itron Riva Dev Mini before the A8 has its power rails in place and steady. Having a voltage on an I/O
Pin on the A8 before it has its Vdd supply can cause permanent damage to the A8.
If you need to create your own power supplies make sure you gate them with 3V3_EXP because
3V3_EXP will not rise until the A8 supply rails are ready. This will prevent you from damaging the A8
processor or other circuitry.

SYS_BOOT CONFIGURATION JUMPERS
The board comes configured to run its preloaded Linux on delivery. It is rarely necessary to change
the configuration jumper or switches.
The A8 can boot from a number of peripherals or memory units. For instance, it can boot from a
UART, USB, I2C, NAND or other sources. Often first stage of booting is used to load a small bootloader
which will then download the full system code. The iSOM module brings two of the system boot
configuration pins out on its connector. The two signals are SYSBOOT0, on J1 pins 1 and 2, and
SYSBOOT4, on J1 pins 3 and 4.
Normally both jumpers will be in the off condition. But occasionally other modes may be required.
For instance, if a download was interrupted leaving bad contents in FLASH the system may appear
dead or not be presenting CCCC. You can configure Sysboot0 jumpered and Sysboot4 unjumpered to
not allow booting from NAND thereby forcing a boot from UART0. This will present CCCC allowing
you to xmodem the SPL file and then ymodem the u-boot program to get a u-boot prompt. Once at
the prompt a “nand erase.chip” will restore the flash to a blank state and a complete reload can be
started.
These two pins are connected to individual mini-jumpers and can be used together to determine the
boot sequence the A8 will use. Typically, the both jumpers are left in the open position.

STARTUP – RIVA ITRON RIVA DEV MINI LINUX FIRST TIME POWER ON
This section covers powering the board on and getting a prompt at the command line. The
information below assumes you are starting with a fresh power-up having had your supply at 0VDC
previously. This is the absolute minimal step to get an operational Linux console.
When shipped from the Itron factory the board is programmed with MLO, u-boot and a valid kernel.
The PIC is also programmed. The two configuration jumpers are also placed in the basic operation
configuration. So on receipt the board should boot into Linux without any changes.
The board can be powered up by using several different methods;
1. Connecting to a solderless breadboard expansion board
2. By direct wiring
3. On a Test Fixture
4. By connecting to another host board.
The following sections explain these methods in detail. Item 4 is not covered because it implies the
user has developed their own host board.
DIRECT WIRING, NO SOLDERLESS BREADBOARD EXPANSION BOARD
Establishing a terminal session is a very simple process. Essentially only +5 VDC is required along
with a console serial port. This is the minimal requirements to boot into a Linux system.
POWER SUPPLIES
Connect +5 VDC through the expansion connector. Leave this turned off for now.
CREATE A CONSOLE PORT
Connect a USB-To-Serial adapter to J4. Some adapters do not require 3.3 VDC so Pin 37 may be
omitted based on the wiring guide provided by the USB adapter manufacturer. More information
about USB-To-Serial adapters is provided later in this document.

SOLDERLESS BREADBOARD EXPANSION BOARD
The easiest way to connect and power the board is to use the solderless breadboard expansion board.
This board breaks the pins out spaced properly to allow the device to be plugged into a solderless
breadboard. Even if not being used with an actual breadboard it provides the typical +5 barrel
connector and 4-pin UART0 connection used on our development kits.
Figure 6 - ACT NIC on Solderless Breadboard Expansion Board
When inserting the Itron Riva Dev Mini/NIC into the expansion board be very careful of orientation.
Note that the mating connector on the expansion board has a label in each side noting which shield
should be visible and power orientation. The “iSOM side” is the side with a single square shield with
the large Itron logo printed on it and the 57088-027 part number. The last 3 digits of the part number
may vary depending on the iSOM configuration.
Simply plug the board into the expansion board, connect a +5 VDC power supply to the barrel
connector (center +) and a serial port to the 4-pin connector. The system is now ready to boot.

ITRON RIVA DEV MINI/NIC TEST FIXTURE
A test fixture has been designed to support programming and testing of the Itron Riva Dev Mini/NIC.
Typically this will be an Itron factory item or an Itron development base. At this time, I do not know
if it will be made available to customers.
This fixture provides the following capabilities:
1. A8 UART0 breakout and Other UARTs
a. JM4 Breakout (40 Pin Expansion Connector) to LEDs and headers
2. A8 JTAG
3. DSP JTAG
4. USB1 Breakout and connector
5. +5 VDC Supply Connector
6. Miscellaneous test point breakout
There is a separate manual that describes this fixture in detail.

POGO-PIN AND SOCKET INFORMATION (SPRING TEST PINS)
Pogo-pins are used for reliable temporary connection between the fixture and the Itron Riva Dev
Mini Under test.
Do not turn the fixture upside down without something to hold the pins in. By their nature the pins
slide in and out of the sockets easily. If you do turn a fixture upside down many, if not all, of the pogo
pins may fall out.
Note that it is nearly impossible to clamp a board onto the fixture with all pins inserted. We
recommend that you only insert the pins that are required for the particular function you are
performing. For instance, it is not necessary to insert all pins for DSP or A8 programming. Pin usage
is shown in the
following section including a map of pins by usage group for each function.
SOCKET
Sockets are used to hold the pogo-pins into the test fixture. They are soldered in but can be replaced.
Different types of pins may be inserted into the sockets as needed.
The pogo-pin socket is QA Technology Company art number 100-SDN2502 a “100 Socket, Sgl PR,
WireWrap”. This socket is press fit into the alignment block and then goes into a PCB hole. The pin is
soldered into the PCB. Because of the way these are mounted it is very difficult to remove or replace
a socket.
The best method is remove a socket is to heat the respective pin at the PCB until the solder melts.
Then pull the socket from the top of the alignment board through the alignment board.
PINS
Three types of pogo-pins are used for this fixture and one type of socket. Pins just slide into and out
of the sockets with no force needed.
SPEAR PIN
This spear pin type used to mate to test points on the Itron Riva Dev Mini PCB. Many useful signals
are brought out on test pins for diagnostics and programming. For instance, all usable GPIO are
brought out to LEDs so they can be flashed for testing. The QA Technology part number for the spear
pin compatible with this fixture is “100-PRN2541L”.
CHISEL TRIAD PIN
The Chisel Triad pin type used to mate to holes in the Itron Riva Dev Mini PCB. Often the fixture will
be used with a Itron Riva Dev Mini that does not have the 40 pin expansion connector populated. The
QA Technology part number for the chisel Triad pin compatible with this fixture is “100-PRN2518L”.
CUP PIN
This Cup pin type used to mate to through hole connectors on the Itron Riva Dev Mini PCB such as an
expansion connector has been soldered onto a board. Cup pins mate to the bottom of the connector
that protrudes through the bottom of the board. The QA Technology part number for the spear pin
compatible with this fixture is “100-PRN2522L”.

GET INTO A TERMINAL
Establish a terminal using a terminal emulator application. This can be done from Windows with
something like Hyperterm or from Linux using minicom. In either case make sure you are connected
to the proper serial port (the USB-To-Serial converter) and have set your configuration to 115200bps
and N81.
GETTING A PROMPT, AND WHAT TO DO WITH IT
It is now time to power-on your board. Once power is applied you should get a prompt after the board
finishes booting. Typically, as shipped from the factory, the system will load u-boot then Linux and
after about a minute will stop at a Linux Prompt. Depending on the state of the firmware in the
module you will get one of the following:
Seen Onscreen
Linux Prompt
u-boot prompt
“C” character stream
Nothing
Description
Meaning
System is up and ready to use
Linux must be loaded
Continuous “C”s The PIC is loaded but MLO, u-boot and the kernel are
about 1 second not
apart
This is an undefined state. It is possible that power is
not being applied, the PIC is not loaded or the system
is bad.
LINUX PROMPT
This verifies that the PIC, MLO, u-boot and a valid kernel are all loaded and have operated
successfully. At this point you can operate the system as any other Linux system.
U-BOOT PROMPT
This means that the PIC, MLO, u-boot are loaded but the kernel is not loaded. This could mean a kernel
is not present in the file system or the kernel image is bad. Reload a kernel image using u-boot and
restart the system.
“C” STREAM (CONTINUOUS “C”S ABOUT 1 SECOND APART)
This means that PIC is loaded but MLO, u-boot and the kernel are not or have bad images. Reload the
firmware starting with MLO and u-boot and verify you can boot with u-boot. Then reload the kernel.
NO PROMPT AT ALL
This is an undefined state. It is possible that power is not being applied, a signal is not tied, the PIC is
not loaded, the kernel or u-boot are not loaded or corrupted. It can also mean that J1 is not placed
correctly.

PIN CONFIGURATION AND USAGE
The A8 is extremely configurable including peripheral to pin assignments. Table 2-7 from TI
document SPRS717B provides the list showing which peripherals can be assigned to which ball (pin)
on the processor package. This table also lists other information about the signal such as its reset
state, drive current, power domain and if there is an internal pull down or pull up resistor.
Most A8 GPIO pins can take the form of up to one of 7 different peripheral functions. Typically,6, at
least in Linux configuration code, the pin is referred to using the name from the PIN name column of
Table 2-7 from TI document SPRS717B. The signal you wish to put onto that pin is chosen by setting
the mode of the port. So to use this pin as a general purpose IO you would set the GPMC_A8 port to
mode 7.
This versatility can make layout easier but it can also produce mutually exclusive situations. For
instance, peripheral A may not be available if you are using peripheral B or if you require peripheral
B to use a particular pin. TI provides a software application that allows you to define your pin usage
and shows any conflicts. It will also export C code that can be used in u-boot or Linux to configure the
pins according to what you have defined.
Typically, IO pin selection is done through u-boot or on kernel setup. At times the kernel definition
may prevent certain pins from being changed from user space commands. But typically, it is possible
to set the port type and direction through the console. Once set the console can be used to control the
pins in some modes. For instance, you can raise and lower GPIO1_24 if GPMC_A8 is set to mode 7 as
shown in the table below.
The following table is a copied section from the A8 Product Preview Document (SPRS717B.PDF). For
detailed pin information and muxing information see that document.
Pin Name Signal Name

GPMC_A8 GPMC_A8

RGMII2_RD3
MMC2_DATA6
IO
GPMC_A24
PR1_MII_RXD0

IO
GPIO1_24
IO
In some cases, Linux requires a pin for its usage or the pin may be used for a dedicated function based
on the platform hardware design. This may make a particular pin unavailable for usage by the
product motherboard designer
I say typically here because a programmer can define a new name and use that in their code. Also some names
are slightly different than the default @defines for some pins.

P4 PIN DESCRIPTIONS
This section describes the pins on P8 that are not connected directly to the A8 processor. For those
connected directly to the A8 processor please refer to the TI AM33xA8ProductPreview document for
details of pin usage. Note that the Linux Device table will specify which pin peripheral is used for each
pin at power up.
P4-1 AND 2 +5.0 VDC
See the earlier section called “Itron Riva Dev Mini Power Supply Handling”
P4-18 HV_CMP
This pin is an input to the PMIC power supply chip on the iSOM module. Its purpose is to notify the
iSOM that power is failing and that it needs to shut down all of its power supply rails as fast as
possible. This is not a graceful shutdown.
A default voltage divider (100k and 28k resistors) holds this pin above 1VDC until the +5VDC supply
drops below 4.6 VDC. If it goes below 1 VDC it will cause a non-graceful shutdown. This input can be
driven below 1 VDC by user circuitry if a forced shutdown is required.
ITRON PROPRIETARY & CONFIDENTIAL INFORMATION
For Reference Only, Printed: 3/6/2018

Riva Edge Mini HW Design and User Guide
Rev 1.01
There is another pin called EPF_IN* that provides a way of letting the system know of an Early Power
Fail condition to permit a graceful shutdown in hardware. Typically, enough capacitance would be
provided on the main (+5V) power supply line to allow the system to run long enough for the power
rails to be cycled down in the appropriate order with the appropriate delays before the HV_CPM
signal is applied through this pin. This signal is an over-ride of the EPF process.
P4-20 EPF_IN* (THIS SECTION REQUIRES WORK)
EPF* is the Early Power Fail input and is an active low. In other words, when EPF* is high there is no
presence of a power failure. EPF* is effectively an input to both the PIC and the A8. EPF* is mainly
used to allow the product motherboard to alert the module that power is about to be lost. It is
typically the first signal to go low when a shutdown is required.
EPF* can be provided to this pin or from circuitry on the board. The on-board circuitry will trigger
EPF* when the +5 VDC rail falls to 4.4 VDC. If you require another voltage, then R45 must be removed
from the board to use this pin.
EPF* is a required part of the power-on sequence and is required before the PIC will activate the
power rails for the A8. Therefor EPF* must be raised after, or simultaneously, when 5VDC is initially
applied. Typically, if there are hold-up capacitors on the main supply rail and EPF* is held low until
they are sufficiently charged to provide enough hold-up power for the system to shut down
gracefully.
If it is not high the PMIC will partially power the module (LDOs) but NOT power the A8 until it goes
high.
During normal operations this pin is used as part of the Early Power Fail system. PON_WAKEUP is
generated as a result of an EPF* signal and some timing delays.
EPF* (Early Power Fail) is created on the motherboard and sent to the module. It informs the A8 that
it must shut down as soon as possible. EPF* also goes to the communications module telling it that it
must send PON (Power Outage Notification) packets. After EPF* occurs the communications module
and the A8 are operating asynchronously with the A8s only job being to get shut down to conserve
power.
While the A8 is shutting down the communications module will put 3 timer values into the PIC via
the I2C bus. The communications module will also then enter a low power mode waiting for the PIC.
PON_WAKEUP is generated when the first timer expires in the PIC causing a PIC internal interrupt.
PON_WAKEUP is a normally low signal that is active high with a programmable high pulse. The
communications module sees PON_WAKEUP as an interrupt and exits low power mode to send a
message packet indicating that there has been a power loss.

Once the PIC generates PON_WAKEUP the next timer value is loaded and the process is repeated a
total of three times. After the communications module has sent its three PON messages it then shuts
down.
P4-26 BATTERY
This is an input to the PCF8546A RTC chip. Its purpose is to provide a method of keeping the RTC
time accurate when there is no main power. The battery voltage can be between .9 and 5.0 VDC and
switchover thresholds can be set by software. Please see the PCF8563A RTC chip datasheet for
configuration and usage of this pin.

DOWNLOADING, IF NECESSARY (LINUX)
The board firmware, and Linux in general, is made up of several images broken into multiple files.
Each file performs a different set of operations at different times. For details of what each file contains
please see a Linux Reference.
You will need the following files:
u-boot-spl.bin
u-boot.bin
MLO
u-boot.img
uImage
For the descriptions below it is assumed that the images are in a folder named images at the root of
your Linux system on your PC. It is also assumed your terminal is connected on /dev/ttyUSB0.
Enter a terminal program such as minicom. Connect to the main terminal port (UART0 by default) at
115800, N-8-1. Power on the board and it will begin outputting a continuous stream of “C” characters
at about 1-2 second intervals if it is an erased board or has the jumpers set as described in an earlier
section,
C:\Users\jbean\Documents\ItronProducts\CTO
Design
Kit\LinuxTestApps\LinuxStuff\TestBuilds\register_hwtest_isom.config_images\bootloader
Wait until you see the “CCC” pattern and then exit the terminal. Now we put small version of u-boot
in RAM that can be used to FLASH the rest of the firmware. On the Linux host command line execute
the following:
sx -k /images/u-boot-spl.bin > /dev/ttyUSB0 < /dev/ttyUSB0
sx -k /images/u-boot.bin > /dev/ttyUSB0 < /dev/ttyUSB0
Once these programs complete re-enter the terminal application with the same settings as before.
Now you are executing the RAM version of u-boot and we can FLASH the rest of the code.
Run loady of MLO (ymodem)
When it completes do the following two commands:
nand erase 0x0 0x20000
nand write.i 0x82000000 0x0 0x20000
Run loady of u-boot.img (ymodem)
When it completes do the following two commands:
nand erase 0x80000 0x60000
nand write.i 0x82000000 0x80000 0x60000
Run loady of uImage (note may take 10 minutes or more depending on kernel size)
When it completes do the following two commands:
nand erase 0x5A0000 0xCE0000
nand write.i 0x82000000 0x5A0000 0xCE0000

Riva Edge Mini HW Design and User Guide
Rev 1.01
All of the code is now Flashed and ready to run. We need to reboot from the new FLASH image. Cycling
power works better but corrupts the RTC when there is no battery. So you may run bootm instead as
follows:
bootm ${loadaddr}
The system should now reboot from the FLASH image. Depending on the image you loaded you may
be given a chance to break the boot process when u-boot completes before getting into Linux.
ERASING FLASH IMAGE
If you need to erase the chip totally killing Linux and u-boot it can be done from u-boot or Linux.
ERASING FLASH IMAGE FROM U-BOOT
From the command line type:
nand erase.chip
ERASING FLASH IMAGE FROM LINUX
From the command line type:
flash_erase /dev/mtd4 0 0
And then:
flash_erase /dev/mtd8 0 0

ITRON RIVA DEV MINI TEST PROCEDURE
This section of the document explains how to perform a basic hardware test on the Riva Edge Mini
using a test fixture, a solderless breadboard adapter or point-to-point wiring.
The tests are described as single item step-by-step actions allowing testing of a single piece of
hardware. For instance, if you are not sure a GPIO is working look up its test below and run its
respective test.
EQUIPMENT REQUIRED:
1.
2.
3.
4.
5.
Itron Riva Dev Mini
Test Fixture (Optional)
Solderless Breadboard Adapter
Bench Power Supply capable of 5 VDC at 1.5 AMPs or greater with Ammeter
USB-To-Serial adapter cable with 4-pin connector or individual pins
a. 3.3 VDC Powered
b. Self Powered
i. Leave Pin 3.3 VDC pin disconnected
6. Oscilloscope or logic analyzer or at a minimum a logic probe.7
7. Multi-meter
MINIMAL OPERATIONAL CONNECTIONS
This section describes how to connect power for each type of fixture or adapter. It also includes
connecting UART0. With these minimal connections you can operate the Linux system from a
terminal as console.
Note when making these connections power should be removed from the system.
We will describe all tests as though you are using a solderless breadboard adapter. Although a little
more complicated than using the test fixture is more likely that a user will have it. There is a
document that describes the test fixture usage on the google drive.
MINI DK TEST FIXTURE
1. Clamp Mini DK onto Test Fixture using spring clamps
2. Ensure that proper pins are inserted in test fixture for
a. +5 VDC to J4 Pin 1
b. Ground to J4 Pin 40
c. RX Pin to J4 Pin 33
d. TX Pin to J4 Pin 35
e. 3.3 VDC Input Pin to J4 Pin 37
i. If this USB-To-Serial adapter creates an output voltage do not connect this pin
Running the test scripts produces slow toggling signals for GPIO pins. Other pins such as I2C and SPI use much
faster signals that may require a scope.

SMOKE/BOOT TEST
1. Perform a visual inspection
a. Watch for shorts, solder blobs or other manufacturing issues
2. Make sure Power Supply is turned off
3. Connect Power Supply and UART as described above
4. Establish a terminal session at 115200, N, 8, 1
5. Prepare to monitor Ammeter
a. If exceeds 200ma immediately remove power
6. Turn on Power8
a. If exceeds 500ma immediately remove power
b. If about 260ma the iSOM (A8) is programmed but DSP isn’t.
c. If about 460ma the iSOM (A8) and DSP are programmed.
7. Watch Terminal for data from Itron Riva Dev Mini
a. If “cccc”, repeating “c”s, then the board is minimally operational as far as hardware
but requires loading of MLO and u-boot and kernel if a kernel is required.
b. If u-boot starts but ends at a u-boot prompt without launching kernel, then the board
is minimally operational as far as hardware but the board requires loading of kernel
if a kernel is required.
c. If Linux Kernel starts and ends with a prompt the board is operational as far as the
Linux System.9
8. Proceed to specific hardware tests described below as needed. All scripts are located at on
the google drive.
Note the currents specified are for Board Revision 2 and may be different for other revisions. It is also possible
that there will be variances board to board depending on software revisions.
9 In this case you can tell if the DSP is programmed and running by looking at the total current draw on the
system. But that does not tell you it is capable of transmitting or receiving.

USB-TO-SERIAL ADAPTERS
Since most PCs no longer have serial ports it is customary to use a USB-to-serial TTL converter cable.
We typically use cables made by FTDI (Future Technology Devices International LTD). It is possible
to use cables from other manufacturers that meet the same specifications. Use the datasheet for the
particular cable you have to identify the 4 required signals (Rx, Tx, Gnd, +3.3VDC In) along with
drawing below to connect your board.
We typically use a USB-to-Serial 11 converter to bring UART0 out as our terminal port. This port
operates in 115kbps N81 format. The adapter is powered by 3.3VDC from the Itron Riva Dev Mini
board.
One cable is the TTL-232R-RPI from FTDI sold by Digi-Key as part number 768-1024-ND. This
cable has 3 wires with connectors designed to be individually placed on individual pins. Because
there are only 3 pins the 3.3 VDC supplies are not connected together.
Figure 8 - FTDI TTL-232R-RPI
Another cable is the TTL-232R-3V3-WE from FTDI sold by Digi-Key as part number 768-1016-ND.
This cable has 6 unterminated wires of which only 4 are used. The image below shows the two ends
of this cable using a 4-pin female connector.

USB CABLES
The board can act as a USB host or a USB peripheral depending on the cable chosen. How the board
acts is determined by using one of the following cables select USB Host or USB peripheral.
AE1450-ND
Board looks like USB 2.0 Cable A Male to Mini B Male 3.28'

powered by Host
10-00003-ND
Board looks like USB 2.0 Cable A Female to Mini A Male
Host, and Powers 0.33' (100.0mm) Shielded
device
To use the ACT board as an USB host the ACT board must be powered by the expansion connector +5
V pins. The white cable with a Mini-A to Type-A Receptacle would be used. The peripheral being
hosted, for instance a thumb drive, would be plugged into Type-Receptacle and Mini-A plug into the
Mini-AB Jack on the board.
To use the ACT board as a USB peripheral the board must be powered by the USB cable12. For this
mode the black cable with a Mini-B to Type-A Plug would be used. The Mini-B would plug into the
ACT board and the Type-A plug would plug into the PC or other host.
This may change. It may be possible to power the board by the expansion connector while it is serving as a
peripheral to allow more power.
