Has anyone succeeded to make OTA's on a BBG eMMC with mender-convert?

Hey everyone.

I’m going to boot BBG from eMMC.

I recently has opened this this topic, but going to make my question easier.

I feel that I’m not the first who trying to use mender-convert on BBB (BBG).
I have tried all images for the last year from rcn-ee.com, but neither works.

Either the bootloader is missing the necessary env variables in the runtime or the image has “broken UEFI support” and it just fails to boot after being mender-convert’ed.

Has anyone ever managed to make BBB running on eMMC perform the update ? I mean using mender-convert’ed vanilla images.
