How to modify the file system mount partition in uboot

[logic887]

How to modify the file system mount partition in uboot on the IMX8MP platform？I modified CONFIG_MMCROOT but it didn't work. After the system restarted, it became mmcroot /dev/mmcblk2p2 rootwait rw again, but I want to mount the file system on /dev/mmcblk2p3

Hello @logic887 

I hope you are doing very well.

Please refer to this thread and let me know if it is working for you.

Basically, ensure that you have this configuration:

CONFIG_BOARD_LATE_INIT=y
CONFIG_BOARD_EARLY_INIT_F=y
CONFIG_SPL_BOARD_INIT=y

Best regards,

Salas.

I am sure these configurations exist in uboot
