Part Number: AM3351

Tool/software: Linux

We are using am335x based custom board with 256MB RAM and 4GB eMMC and SPI EEPROM.

We want to enable POST(power on self test) from SPL. (version: U-Boot-2017.01).

We are mainly interested in DDR test and SPI eeprom test, is it possible to use POST, if yes how ?

When I try to enable POST i am getting following error

../include/post.h:60:2: error: #error "_POST_WORD_ADDR currently not implemented for this platform!"
 #error "_POST_WORD_ADDR currently not implemented for this platform!"

Thanks,

Regards,

Hi Ankur
in uboot can you try the following

mtest - simple RAM read/write test

thanks

And to add to Mohsen's post, we do not enable CONFIG_POST in the SDK so none of the POST routines that would run are not there. If you want to add POST, see the u-boot doc/README.POST file. mtest is a memory tester in u-boot.
