Unable to save uboot environment to eMMC in STM32MP157F-DK2

[ThinhNguyen]

I use default uboot in openSTLinux. I use the command below to save uboot environment.

$ env save

 but it showed an error, and the environement did not save. please see the picture below.

How to fix it?

[ThinhNguyen · Accepted solution]

To Fix it modify uboot configuration. Below is an example:

CONFIG_ENV_OFFSET=0x884400

CONFIG_ENV_SIZE=0x4000

CONFIG_ENV_OFFSET_REDUND=0x8C4200

CONFIG_ENV_SIZE_REDUND=0x4000

CONFIG_SYS_MMC_ENV_DEV=0

For the Environment offset, please prefer to Flash layout to find the corect value.
