Hi Drew

Thank you for the quick reply. Its really appreciated 🙂

I manged to build the image, though I didn’t have to make any changes to u-boot-imx.bbappend nor to u-boot-variscite.bbappend. I just enabled “mender-uboot” feature in the local.conf file (MENDER\_FEATURES\_ENABLE\_append = " mender-image-sd mender-uboot" ). For other Linux distributions (Sumo) I did not have to add this, and the integration was successful, so its a bit strange I had to do it this time.

Nevertheless, even though the image was built successfully, it is not booting. Serial boot messages show this error message: “Bad Linux ARM64 Image magic!”

Here are the full boot messages:

After going though posts from people facing similar error:

[https://hub.mender.io/t/issue-with-variscite-var-som-mx8m-nano/2840/11](https://hub.mender.io/t/issue-with-variscite-var-som-mx8m-nano/2840/11)

I made a couple of changes to the local.conf according to those posts, but I am still getting the same error message.

local.conf:

Do have any suggestions to how I can fix this problem? Thank you
