MPC837xE-RDS, Rev. 1.010 Freescale Semiconductor Preliminary, Subject to Change without NoticeMPC837xE-RDS Board2.1 Board-Level FunctionsThe board-level functions discussed in this section are reset, interrupts, clock distribution, and interface specification.2.1.1 Reset and Reset ConfigurationsThe MPC837xE-RDS reset module generates a single reset to reset the MPC837xE and other peripherals on the board. The reset unit provides power-on reset, hard reset, and soft reset signals in compliance with the MPC837xE hardware specification. Figure 2 shows the reset circuitry.Figure 2. Reset Circuitry of the MPC837xE• The COP/JTAG port or the MPC837xE generates the signal for hard reset.• The Maxim MAX6829 device generates the power-on reset. When MR is de-asserted and 3.3 V is ready, the MAX6829 internal timeout guarantees a minimum reset active time of 140 ms before PORESET is de-asserted. This circuitry guarantees a 140 ms PORESET pulse width after 3.3 V reaches the right voltage level, and this meets the specification of the PORESET input of MPC837xE.• The COP/JTAG port reset provides convenient hard-reset capability for a COP/JTAG controller. The RESET line is available at the COP/JTAG port connector. The COP/JTAG controller can directly generate the hard-reset signal by asserting this line low.• The pushbutton reset interfaces the MR signal with a debounce capability to produce a manual master reset of the processor.MAX68293.3 V Push ButtonHRESET from COPSRESET from COPTRST from COPSRESET to MPC837xEPORESET to MPC837xEFLASH10/100/1000 PHYMPC837xETRST to MPC837xEGND1.0 VMRWatchdog Input from MPC837xEPCI-E & Mini PCI-E

MPC837xE-RDS BoardMPC837xE-RDS, Rev. 1.0Freescale Semiconductor 11 Preliminary, Subject to Change without Notice• The COP/JTAG port also generates the soft reset for the system. Assertion of SRESET causes the MPC837xE to abort all current internal and external transactions and set most registers to their default values.2.1.2 External InterruptsFigure 3 shows the external interrupt circuitry to the MPC837xE.Figure 3. MPC837xE Interrupt CircuitryThe following items describe the interrupt signals shown in Figure 3:• PHY interrupt (TSEC1_IRQ, TSEC2_IRQ). Two RTL8211B GBE PHY interrupts are connected to IRQ1 and IRQ2 of the MPC837xE. The system software can detect the status of the Ethernet link and the PHY internal status. • SD Card Write Protect interrupt (SD_WP). The SD card socket has a mechanical pin that can indicate whether the SD card inserted is write-protected or not. It is connected to IRQ4 of the MPC837xE.• PCI interrupt (PCI_INTA, PCI_INTB).

The DDR2 interface uses the SSTL2 driver/receiver and 1.8 V power. A Vref 1.8V/2 is needed for all SSTL2 receivers in the DDR2 interface. For details on DDR timing design and termination, refer to the Freescale application note entitled Hardware and Layout Design Considerations for DDR Memory Interfaces (AN2582). Figure 5 shows the DDR SDRAM controller connection.Table 1. Clock DistributionClock Frequency Module Generated by Description66.666 MHz MPC837xE CLKIN 66.666 MHz oscillator The MPC837xE uses CLKIN to generate the PCI_SYNC_OUT clock signal, which is fed back to the internal system PLL through the PCI_SYNC_IN signal. From the power-on reset configuration, the internal PLL generates the CSB clock, which is fed to the e300 core PLL for generating the e300 core clock. The PCI M66EN pin is inverted for CFG_CLKIN_DIV configuration input, which selects whether the PCI_SYNC_OUT signal is CLKIN or CLkIN/2.125 MHz MPC837xE eTSEC RTL8211B The gigabit Ethernet PHY (RTL8211B) provides a 125-MHZ clock for eTSEC operation.)200 MHz DDR2 SDRAM MPC837xE The DDR memory controller is configured to use the 1:1 mode CSB to DDR clock for the DDR interface.

DDR2 SDRAM Connection2.1.5 Local Bus ControllerThe MPC837xE local bus controller has a 32-bit LAD[0–31] address that consists of data multiplex bus and control signals. The local bus speed is up to 133 MHz. To interface with the standard memory device, an address latch must provide the address signals. The LALE is used as the latching signal. To reduce the load of the high speed 32-bit local bus interface, there is a data buffer for all low-speed devices attached to the memory controller.

MPC837xE acts as I2C master and it is connected to the M24256 serial EEPROM using I2C1 as shown in Figure 18. Figure 18. I2C EEPROMYou can use the M24256 serial EEPROM to store the reset configuration word of the MPC837xE, as well as store the configuration registers’ values and user program if the boot sequencer of MPC837xE is enabled.For more details about programming the reset configuration word value in I2C EEPROM and the boot sequencer mode, refer to the MPC8379ERM. The I2C address of the M24256 EEPROM on the bus is 0x50.2.5.2 PCI Operating FrequencyAn M66EN input pin determines the AC timing of the PCI interface. On the MPC837xE-RDS board, the PCI agent card—connected to a mini PCI slot—determines the M66EN signal level. If a 33-MHz-only card is inserted, the M66EN signal is driven to 0 by the PCI agent card according to the PCI specification, or it is driven to 1 if it can perform at 66 MHz. A NOT gate inverts the signal and drives the CFG_CLKIN_DIV input pin so the system clock continues at the same frequency. I2C1-SCLI2C EEROMM24256MPC837xESCLSDAI2C1-SDAI2C Address = 0x50

MPC837xE-RDS, Rev. 1.026 Freescale Semiconductor Preliminary, Subject to Change without NoticeMPC837xE-RDS Board2.5.3 Reset Configuration WordThe reset configuration word (RCW) controls the clock ratios and other basic device functions, such as PCI host or agent mode, boot location, TSEC modes, and endian mode. The reset configuration word is divided into reset configuration word lower (RCWL) and reset configuration word higher (RCWH) and is loaded from the local bus during the power-on or hard reset flow. The default RCW low-bit setting is 0x0404_0000. The default RCW high-bit setting is 0xA060_6C02.The RCW is located at the lowest 64 bits of the boot Flash memory, which is 0xFC00_0000 on this board.Figure 19 and Figure 20 show the RCW definitions.Table 5.

If so, simply reset the product to resume normal operation by following the steps in the software user guide. If normal function does not return, please move the product to another location.4 MPC837xE-RDS SoftwareThe MPC837xE-RDS comes with a pre-installed reference design software package. This package consists of a bootloader (u-boot), a generic PPC Linux-based system, and a suite of Wi-Fi router applications. The software all resides in the on-board Flash memory. Upon powerup, the Linux system and the applications run on the MPC837xE-RDS.The MPC837xE-RDS reference software takes advantage of a tool called OpenWRT, a Linux platform for embedded devices. Instead of trying to create a single, static firmware, OpenWrt provides a fully writable file system with package management. This frees you from the application selection and configuration, allowing you to customize the device through the use of packages to suit any application.4.1 Application Features for MPC837xE-RDS reference softwareThe pre-installed reference design software supports the application of the Wi-Fi router, including the following:• 802.11 a/b/g/n• IPv4 and IPv6• DHCP• DNS•VLAN• NAT and PAT• Static routing• RIP v1, v2•VRRP48V Power WAN(Support PoE)LAN eSATA Reset USBSD Card

MPC837xE-RDS Application ConnectionsConfigure the MPC837xE-RDS board by using a web browser. Connect your PC to the LAN port of the board (either directly or through a hub), then use a web browser to configure. TCP/IP settings must be correct. The TCP/IP setting should be on the IP subnet of the MPC837xE-RDS.• Set up the IP Address automatically:— MPC837xE-RDS incorporates a DHCP server. The easiest method is to set your PC to get its IP address automatically and correctly obtain the correct IP address, gateway, and DNS.• Set up the IP Address manually:— The default IP address of MPC837xR-RDS reference board is 192.168.1.1/24. Set the IP address of the PC as 192.168.1.xxx/24, where xxx can be any number between 2 and 254, and the set the default gateway to 192.168.1.1.After setting the IP address, open a web browser and type address http://192.168.1.1. At the login window, type admin for both User name and Password. You will then arrive at the MPC837xR-RDS main page. After that, you can review and modify the configuration as needed. For more information, refer to the software user guide.Besides acting as one Wi-Fi router, MPC837xE-RDS platform can also support other utilities and applications.
