imx7d pico pi, Invalid vbmeta image about cookers HOT 7 CLOSED

I think the root cause is in gen_virtual_images command.
Please use this command on host PC side, don't in the container because container cannot access hardware relate nodes.

If still doesn't works, please provide gen_virtual_images output log to me, thanks.

When you say host pc side, you mean not in the docker container right? Not outside of the virtual box I am running it on.

Right, only compile source code in the docker container, and make image outside the container, still doesn’t works?

Unsure, I am going to try it but I am a bit sceptical about this gen_virtual_images function.
Like why does it make the partitions twice, once after it has detached the loop device.

Edit:
I did try fixing that function previously but that didn't work either. However if you want I could try that again but running outside of the docker container.

So I made some changes to the gen_virtual_images function and now it works.

I essentially added some syncs, made sure to run loop_dev=$(losetup | grep "test.img" | awk '{print $1}') after each kpartx -av in case it gets assigned to a different loop device, and then I probably went a bit overboard with kpartx -d for both the loop device and img to make absolutely certain that the device is detached before attaching it again.

If you want I can make it into a merge request?

That strange, I remember I tested before.
Anyway, thanks for your test, you can make a PR to this repo of course.

I created a pull request. Thank you very much for the help.
