This is not the right way to fix it. Yes your device has booted but it is missing a Mender integration in the bootloader. So this would need to be resolved first before moving on trying things out in user-space.

I guess best resource we have on U-boot integrations are:

- [Mender from scratch](https://hub.mender.io/t/mender-from-scratch/391)
- [Manual U-Boot integration | Mender documentation](https://docs.mender.io/2.1/devices/yocto-project/bootloader-support/u-boot/manual-u-boot-integration)
