- u-boot for the TI OMAP730 Perseus2
-
- Dave Peverley, MPC-Data Limited
- http://www.mpc-data.co.uk
-
-
-Overview :
-
- As the OMAP730 is similar to the OMAP1610 in many ways, this port was based
-on the u-boot port to the OMAP1610 Innovator. 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.
