Hello everyone,
I am currently struggeling with mender-convert on a beaglebone green wireless (which is mostly identical to a beaglebone black)
When I use the stock image bone-debian-10.3-iot-armhf-2020-04-06-4gb.img.xz and convert it with mender-convert everything works as expected.
Then I installed a newer kernel with the script provided in the original image:
debian@beaglebone:/opt/scripts$ git pull
debian@beaglebone:/opt/scripts$ sudo tools/update_kernel.sh --lts-5_10
The update works flawless and the device is still bootable and correctly boots using the new kernel.
Afterwards I get an image of the sd card and use it with mender-convert. I flash the resulting *.img file to another sd card and try to boot my BB from that SD card there are two scenarios:
Scenario 1: Don’t push the boot button on the Board.
In that case the Boot process fails and runs in an infinte loop:

Please note, that there is absolutely no issue when NOT updating the kernel. But since the “non-mender” image runs with a newer kernel flawless I am wondering where things go wrong.
I have seen this topic with a similar problem, but it was abandonned without a solution.
Does anyone have an idea of what’s happening, or give me some pointers in the right direction how to track down the issue?
Any ideas are appreciated.
