Part Number: PROCESSOR-SDK-AM64X
Hi
May I have question about processor-sdk's U-boot?
I used u-boot-spl/bl31/bl32 prebuilt image for make linux.appimage.
And boot from eMMC.
So I shoud change U-boot environment variable (ex. mmcdev/bootpart) from U-boot.
But I cannot use "saveenv" command, So I can not save and must change environment variables each time the processor booting.
Is there any way to enable "saveenv" command?
Or Is there any way to change environment variable from u-boot?
