TDA4AL-Q1: How to build the fw_printenv into rootfs?

Hello, 

I need to check internally if we are supporting this out of the box. 

Which version of SDK are you using? Is this a custom board or the TI EVM that you are using? 

Best regards,

Keerthy 

Hi Keerthy:

      I used custom board. And use eMMC boot.

Below is bike build export variable.

export TI_TARGET_PROJECT=tisdk-default-image
export MACHINE="j721s2-evm"

Check my repo manifest file show 10.00.00. 

<default remote="MD" revision="TI/TDA4AL/10.00.00" sync-j="4"/>

Hi Keerthy:

In the u-boot, I have enable to saveenv. Modified the config file j721s2_evm_a72_defconfig.

CONFIG_ENV_SIZE=0x20000
CONFIG_ENV_OFFSET=0x00680000

# CONFIG_SYS_REDUNDAND_ENVIRONMENT is not set

CONFIG_ENV_IS_IN_MMC=y
CONFIG_CMD_SAVEENV=y
CONFIG_CMD_ERASEENV=y
CONFIG_SYS_MMC_ENV_DEV=0
CONFIG_SYS_MMC_ENV_PART=1
CONFIG_CMD_NVEDIT_INFO=y

Hi Keerthy:

       Our SDK version is 10.00.00.08
