Hi! I’m also relatively new to Yocto and Mender, so this may not be an optimal solution, but it’s working for us.

In my `meta-myproject` layer I created a `recipes-bsp/` directory containing these files:

`./u-boot/u-boot_%.bbappend`:

```auto
FILESEXTRAPATHS_prepend := "${THISDIR}/files:"
SRC_URI_append += "file://no_config_env_is_in_fat.cfg"

```

This is a relatively simple bbappend file that adds the `./files/` directory to the search path, and then tells the recipe to include the new `no_config_env_is_in_fat.cfg` file, which it somehow knows is a config file (maybe it assumes that for `.cfg` files, maybe it parses the file, I’m not sure).

`./u-boot/files/no_config_env_is_in_fat.cfg`:

```auto
CONFIG_ENV_IS_IN_FAT=n

```

This KCONF snippet changes the compilation options for u-boot, to disable support for storing the env in fat.

Hope that helps!
