Hi Expert,
Customized board cannot boot
ti-processor-sdk-linux-am335x-evm-08.02.00.24
Could you help to give some suggestions?
Thanks
Daniel
Hi Hong
1/, is it TI reference board or customer board?
customer board
2/. what is SYSBOOT pins configuration on board?
3/. what is intended boot media on board?
SD CARD
Thanks
Daniel
Hi Hong:
Thanks for your response,
This board is working in very old SDK version(ti-processor-sdk-linux-am335x-evm06.00.00.00), but I cannot boot it for ti-processor-sdk-linux-am335x-evm-08.02.00.24
No message showed when I input thoes command.
Please see u-boot-log.txt for full log

Hi Hong:
My dm tree screen is below
I can see "mmc 0 [ + ] omap_hsmmc |-- mmc@48060000",
I also check the "dm tree" for my TI3358_GP board with same sdcard, I got the same result.
what should I check next step?
Thanks

Hi Hong:
My dm tree screen is below
I refer to https://e2e.ti.com/support/processors-group/processors/f/processors-forum/814034/linux-am3358-custom-board-boot-issue
I follow the post to add CONFIG_MMC_BROKEN_CD=y in am335x_evm_defconfig
My board boot successfully, :D
Thanks
