6/21 3 HW requirements Since the NANO USB stick has no I/O connections or LEDs for user interface it is recommended to use a standard CC2531 USB dongle for SW development and prototyping before loading the code onto the NANO USB stick. The NANO USB stick is compatible with regards to USB interface and radio interface to the standard CC2531 USB dongle.

Hence it is recommended to use the USB bootloader code programmed into the device for loading application code onto the device. All unused I/Os should be configured as input pull-down at the beginning of your application to reduce current consumption. 4 NANO USB Stick Serial Boot Loader This section will guide you through the steps needed to build a Serial Boot Loader (SBL) for a Z-stack and for an RF4CE application and will explain you how to modify such an application to be compatible with the SBL. The SBL is provided as a value-enhancing sample solution that enables the updating of code in devices without the cost of maintaining any download-related code in the user application other than ensuring a compatible flash memory mapping of the final output. SBL is effected as a managed client-server mechanism which requires a serial master to drive the process (i.e. a PC GUI application with access to the serial connection to the CC2531.) Since the NANO USB stick has no human interface such as keys, the boot loader will always automatically start before the application, wait for a potential application downloading during ~15sec, and then automatically jump to the application if any valid image is already loaded in flash. If not, it will wait for an application downloading forever. Therefore, when the SBL will be loaded into flash memory, each time you connect your NANO USB stick into a USB port you will have around 15 seconds to download your new application. Then the SBL will jump to the existing application and you won’t be able to download your new application anymore. The following sections will walk you through the steps needed to build and download the SBL, then build and download an SBL compatible application using IAR to finally load your application on the NANO USB stick using SBDemo tool. 4.1 Software required File name Description Link Bootloader_xxx.hex Bootloader hex file Wiki ZIP archive : File:NANO-USB package.zip SBDemo Serial Bootloader PC interface demo application, used to load binary files with the bootloader znp.bat, znp.js, sim2bin.exe for a Z-stack application pp_cc2531f256sb.bat, oadbbin.exe for a RemoTI stack application scripts and executable files performing file conversion

These linker files are automatically installed with the Z-stack and the RemoTI stack under, respectively, \Projects\zstack\Tools\CC2530DB and \Projects\RemoTI\common\cc2530 - USB Drivers (usb_cdc_driver_cc2531_PID16B2.inf and usb_cdc_driver_cc2531_PID16A8.inf) 4.2 SBL Boot Code Image If the SBL is already loaded on your target, skip this section. This section will guide you through the steps needed to program the Bootloader image into flash using Texas Instrument SmartRF Programmer. The project for the boot image already exists, so all you need to do here is open the project, rebuild it and download the output .hex file with SmartRF Programmer. But before downloading the SBL, you may want to tune the period during which the SBL waits for an application to be downloaded (it happens after powercycling the device, the default setting is around 15 sec). To do that, just modify the SBL_WAIT_PERIOD value defined in the Constants section in the main file of the SBL project, called either sb_main.c for the Z-stack bootloader, or main_cc2531.c for the RemoTI stack. This waiting period is not implemented with timers, it simply uses a while loop statement decrementing the SBL_WAIT_PERIOD value. This value is initialized to a non-zero value, and when it reaches zero the SBL jumps to the application. Therefore the conversion between the variable value and corresponding time is approached by the relation: For Z-stack SBL : SBL_WAIT_PERIOD = 21 845 * X, where X is the waiting period in seconds. For RemoTI SBL : SBL_WAIT_PERIOD = 23 130 * X, where X is the waiting period in seconds. Modify the value and rebuild the project. Then you can download the SBL on the target. 4.3 Download the Serial Bootloader 1. Open Texas Instruments SmartRF Programmer 2. SelectProgram CCxxxx SoC or MSP430 under What do you want to program ? 3. Select System-on-chip tab 4. Browse the Flash image field to the .hex object file of the SBL
9/21 5. First Erase the flash by selecting Erase in Actions and then click Perform Actions 6. Then program the flash by selececting Erase and Program or Erase, program and verify, then click Perform actions. 4.4 SBL Compatible Application Code Image In this section you will be guided through the steps needed to convert an already existing Z-Stack 2.4.0 or RemoTI 1.2.1 application (in this case the RemoTI RNP application and, in parallel, the Z-stack ZNP application) into one that is compatible with the SBL. The application needs to be modified such that it does not overwrite the SBL that has been programmed into flash in the previous section. After the project has been modified to be SBL compatible the final steps in this section will program the SBL compatible application into flash using SBDemo. 4.5 Generating a Binary file: The project must be modified to produce a binary file that can be downloaded by the SBL PC Application “SBDemo.exe”. This will be used in later sections. In IAR, open your project, here we will use RNP and ZNP projects: 1. File->Open->Open workspace 2. Browse to and open a. for the Z-Stack: " Projects\zstack\ZNP\CC253x\ znp.eww " b. for the RemoTI stack: “Projects\RemoTI\RNP\CC2530EB\ rnp_cc2530.eww” 3. From the project view in Left panel click on the drop down box at the top 4. Select a. For the Z-stack: “CC2531 – ProdSBL” b. For the RemoTI stack: “CC2531F256_SB” 5. Project->Options 6. Select "Build Actions" category in left panel 7. Depending on the stack you will use, different tools will be used to generate a binary file:
10/21 a. For the Z-stack: Add the following line to the "Post-build command line": "$PROJ_DIR$\tools\znp.bat" "$PROJ_DIR$\tools" "CC2531-ProdSBL" b. For the RemoTI stack:Add the following line to the "Post-build command line": "$PROJ_DIR$\pp_cc2531f256sb.bat" "$PROJ_DIR$" 8. Now select "Linker" category in the left panel a. For the Z-stack : in the Ouput tab, in the Format section, select Other, then Output Format: simple-code and Format variant: None
11/21 b.1) For the RemoTI stack : in the Output tab, in the Fornat Section, select Debug information for C-SPY, and check "With runtime control modules" and "Allow C-SPY - specific extra ouput file" b.2) in the Extra Ouput tab, check Generate extra ouput file and in the Format section select Ouput format : raw-binary and Format variant : None
12/21 9. For the Z-stack-based ZNP project only: a. Select "C/C++ Compiler" category in left panel b. Select "Preprocessor" tab in right panel c. At the bottom of the "Defined Symbols: (one per line)" list add (on a new line) MAKE_CRC_SHD (it resets the CRC located at 0x2092-0x2093 in CODE to 0xFFFF value)
13/21 4.5.1 Note on the batch files: znp.bat and pp_cc2531f256sb.bat use tools located in different directories, therefore be careful to respect the proper location of your files: znp.bat : calls znp.js which shall be located in "$PROJ_DIR$\tools" (1st option of znp.bat) where $PROJ_DIR$ refers to your project directory containing znp.eww. znp.js usessim2bin.exe wich actually converts a .sim file into a .bin file. The .sim file is an output of IAR, sim2bin.exe fetches it in the "CC2531-ProdSBL" (2nd option of znp.bat) directory located in the project directory. Ensure that all the files and directories are properly located and named. pp_cc2531f256sb.bat : calls oadbbin.exe located in "$PROJ_DIR$\..\..\common\cc2530\”, where one “..\” means one on-directory. oadbbin.exe uses rnp_cc2531.a51 (ouput of IAR) located in "$PROJ_DIR$\CC2531F256_SB\Exe\” and creates rnp_cc2531.bin located in "$PROJ_DIR$\CC2531F256_SB\Exe\”. Ensure that all the files and directories are properly located and named. This remark holds for the linker file location, cf. below. 4.5.2 Modify the code placement: The SBL resides in the beginning of flash. So the linker command file needs to place the application image in an area of memory that does not overlap the SBL (and further more at a start address expected by the SBL). 1. On the left pannel select Linker 2. Select "Config" tab. 3. Change the linker command file to: a. For the Z-stack: $PROJ_DIR$\..\..\Tools\CC2530DB\cc2530-sb.xcl b. For the RemoTI stack: $PROJ_DIR$\..\..\common\cc2530\ti_51ew_cc2531f256_sb.xcl 4. Rebuild your project.
14/21 4.6 Download a New Application Image via SBL Once an SBL compatible binary file has been generated, you can download it on the NANO USB stick using the SBDemo tool. 4.6.1 Serially boot the new Application Image (binary file): 1. Connect the NANO USB stick into a USB port 2. Open SBDemo.exe 3. Click on the “...” button and browse to your application image, ex: a. For the Z-stack: “Projects\zstack\ZNP\CC253x\dev\ CC2531ZNP-Prod.bin” b. For the RemoTI stack: “Projects\RemoTI\RNP\CC2530EB\CC2531F256_SB\Exe\ rnp_cc2531.bin” 4. Click on the Open button. 5. Enter the COM Port of the SBL (cf. Device Manager) 6. Click on the "Load Image" button to send the file. 7. The file will take a couple of seconds to download and verify. 8. Power cycle the NANO USB stick
15/21 4.6.2 Remark about the Application The NANO USB stick dongle has almost* all of its pins connected to ground; therefore you should set these pins to be input pull-down at the beginning of your application to reduce current consumption. After a reset the default state is input pullup for all GPIOs. * Port0, Port1 and I/O 2.0, 2,3, 2.4 4.7 Common Issues 4.7.1 SmartRF Programmer bug: Sometimes the SmartRF Programmer window gets out of the screen so you can’t see it anymore but it is still present in the task bar. Therefore you just need to move the window back into the screen: 1. Left click on the application in the task bar to select it 2. Right click on the application in the task bar 3. Click on Move 4. Hit any array button (up/down/left right) on your keyboard to enable the Move command 5. Move your mouse until you see the smart RF window appear on your screen. 4.7.2 USB Driver issues: When you connect a NANO USB stick for the first time in a USB port, Microsoft Windows may automatically install the corect driver. If it does, you should then see your NANO USB stick appear in the Ports (COM & LPT) list in the Device Manager, labeled either RemoTI Network Processor or TI CC2531 Low Power RF to USB CDC Serial Port. If Windows does not install the correct driver, or does not install anything, find your NANO USB stick in the Ports list (check under Universal Serial Bus Controller as an Unknown device or under Cebal controlled devices) and do the following: 1. Right click on the label in the Port list 2. Click on Update Driver… 3. Select No, not this time and click Next 4. Select Install from a list or specific location (Advanced) and click Next 5. Select Don’t search. I will choose the driver to install. And click Next 6. Click on Have Disk 7. Browse to either usb_cdc_driver_cc2531_PID16A8.inf or usb_cdc_driver_cc2531_PID16B2.inf.Try both of them, if the first one does not work, the second one should. 5 Schematic and Layout The complete design files including schematic and layout for the NANO USB stick is available upon request from lpwsupport@ti.com 6 Document history Revision Date Description/Changes - 2011-06-03 First revision. 1.0 2011-08-15 Updated with safety information EVALUATION BOARD/KIT/MODULE (EVM) ADDITIONAL TERMS
