How to store the u-boot-env on mmc so that fw_printenv can access it.

[Hammy]

The default configuration for the trusted defconfig has CONFIG_ENV_IS_NOWHERE=y . How can I store the u-boot-env on mmc such that fw_printenv can read it. When I took out CONFIG_ENV_IS_NOWHERE I am unable to get the boot process to u-boot. The last thing I get is

and then a watchdog timer. My gpt image looks like this.

Hi,

do you got this while trying to flash the image?

[Hammy]

Yes

[SMich.1]

Your problem not with u-boot env .

You cannot flash with mender compiled fsbl and fip . I mean that the first two files:

#Opt Id Name Type IP Offset Binary

- 0x01 fsbl-boot Binary none 0x0 arm-trusted-firmware/tf-a-stm32mp153a-mx-usb.stm32

- 0x03 fip-boot FIP none 0x0 fip/fip-stm32mp153a-mx-trusted.bin

you need to build one time without mender layer save this files a side and then to make image with mender.
