Part Number: AM5718

Hi,

i'm using processor-sdk-u-boot-2019.01

Some commands fail when u-boot is booted with eMMC

"saveenv"

I booted into eMMC without an SD card, but the environment variables seem to be stored in the SDcard area.

I found similar e2e content, but I can't apply it because the U-boot version is different.

Is it possible to set FAT_ENV_DEVICE_AND_PART in u-boot-2019.01 version?

Please help to set ENV in emmc area

Thank you

Hi Minsun,

Please git am the attached patch on u-boot tree and try saveenv. I have tried saveenv with card removed
and i was successful in saving environment. Basically removed saving into SD and saving it in eMMC instead.

Thanks,
Keerthy
