imx6qsabresd saveenv not working

rakesh3 — Mon, 28 Aug 2023 13:37:24 GMT

HI team,

I am using the imx6sabresd board and trying to save the local uboot environment variable persistent across reboot. But its not able to save the variable after reboot .

example:

>setenv demo 100

> saveenv
Saving Environment to MMC... Writing to MMC(3)... OK

But after reboot when checked ..

> printenv demo
## Error: "demo" not defined

Below is my u-boot configuration .

CONFIG_ENV_SUPPORT=y
CONFIG_SAVEENV=y
CONFIG_CMD_SAVEENV =y

CONFIG_ENV_OFFSET=0xE0000
# CONFIG_CMD_ERASEENV is not set
CONFIG_CMD_TFTPBOOT=y
# CONFIG_ENV_IS_NOWHERE is not set
CONFIG_ENV_IS_IN_MMC=y
CONFIG_SYS_MMC_ENV_DEV=2
CONFIG_SYS_MMC_ENV_PART=0
# CONFIG_SUPPORT_EMMC_BOOT is not set

Please suggest me on this issue what I am missing to make the uboot variable work persistent across reboot .?

I have attached the custom configuration for board. Please have a look for it

Does it compulsory need the fast boot config for it to work ?

You'd better to check the boot log if the env read from mmc 3 correctly.
