Hi,
thanks

Regarding BOOTARGS:
I falsely understood “root=” as part of it . And thought it made sense to have the root device fixed.
I removed that part and have a clean boot.

Regarding dtbo’s:
The “Misaligned operation” message does not seem to be a problem but just information. Even if i tried to make an empty list for dtbo there are still two.

Tomorrow i will try and burn the lock fuse and then set the post to solved - and then go back to my original task with custom modifications :slight_smile:

Regards and thanks
Paul

A little surprice

## U-Boot CLI access is disabled due to Secure Boot

But everything boots OK

Thanks for the feedback, @pfarre !

And I forgot to comment about this. I was informed that although this is just a warning, maybe this is something that should be looked into. So could you please create an issue in meta-toradex-security: https://github.com/toradex/meta-toradex-security/issues

Best regards,
