Supported features are : - - - Serial terminal support - - Onboard NOR Flash - - Ethernet via the seperate debug board - - Tested on Rev4 and Rev5 boards - - It has also been tested to work correctly when built with a 'standard' GCC -3.2.1 cross-compiler as well as Montavista Linux CEE 3.1's toolchain. - - -Hardware Configuration : - - The main dips on the P2 board should be set to 2,3,7 and 9 on with all -others off. On the debug board, dips 1 and 7 should be on with the rest off. -The serial console has been set up to run from the DB9 connector on the -P2 board at 115200 baud, 8 data bits, no stop bits, 1 parity bit. - - It should be noted that the P2 board has NOR flash that is addressable via -either CS0 or CS3. This mode can be changed via DIP9 on the P2 board. - - -Installing u-boot for the P2 : - - You can simply build u-boot for the Perseus by following the instructions -in the main readme file. The target configuration is "omap730p2_config". -Once u-boot has been built, you should strip the executable so it can be -loaded via CCS (which cant cope with the symbols in the ELF binary) : - $ cp u-boot u-boot.out - $ arm-linux-strip u-boot.out - - The method we've used for installing u-boot the first time on a P2 is -as follows : - -1) Configure TI Code Composer Studio to connect to the P2 board via JTAG - as described in the Users Guide. - -2) Set up the P2 to boot from CS3, and connect with CCS. Reset the CPU - and run the "init_mmu" GEL script. - -3) Use the "Load Program" option to send the u-boot.out file to the P2 and - run. - - At this point, u-boot should run and you will see the boot menu on your -serial terminal. You can then load the u-boot image to memory : - - # loadb 0x10000000 - - Send the "u-boot.bin" binary via the serial using Kermit. Once loaded -you can self-flash u-boot : - - # protect off 1:0 - # erase 1:0 - # cp.b 0x10000000 0x0 0x20000 - - You should now be able to reset the board and run u-boot from flash. - - -Alternative flash option : - - Sometimes, if you've been silly, you can get the board into a state where -whats in flash has upset the board so much that you can no longer connect -to the P2 via JTAG. However, you can set DIP9 to off to swap the boot mode -of the P2 so that you boot from RAM instead of NOR flash. This moves NOR -flash up to 0x0C000000. You can build a special version of u-boot to -utilise this by the following config : - - $ make omap730p2_cs0boot_config - - If you load this up via CCS it will detect flash at its alternate location -and allow you to programme your u-boot image (which, remember must be built -for CS3 boot!) Once you do this, you can revert to CS3 boot and it will work -fine again. - - -Errata : - -1) It's been observed that sometimes the tftp transfer of kernels to the - board can have checksum errors or stall. This appears to be an issue - with the lan91c96.c driver, and can normally be worked around by - resetting the board and trying again. |
