Linux/PROCESSOR-SDK-AM437X: ID memory check

Zhiwei Wang

Tool/software: Linux

Hi,

For some reason, we might messed up the ID memory content so the board can no longer boot. I would like to know if we can skip the ID memory read from U-Boot? If so, how?

Thanks.

Hello Jerry,

Here in this patch you can see how to skip the ID memory checks by replacing the "am_ep.name" with the correct board name from <Processor SDK>/board-support/u-boot-<version>/board/ti/am43xx/board.h.

Later use these commands to program your EEPROM in U-Boot or these to program it in Linux.

You can find the AM437x GP EVM I2C ID Memory layout here.

Best regards,
Kemal

Hi, Kemal,

Thanks for reply. I have applied the patch (and added more on my own to bypass the eeprom read) and it does not help. My board still not booting and no output on console.

What else could prevent output on console?

Thank.

Please, write down which board do you have and which exact Processor SDK version are you using? Also attach the changes.log generated by this command.
cd <Processor SDK>/board-support/u-boot-<version>/
git diff > changes.log
