I’m working on a device tree customization with Torizoncore and I need to see why the boot is failing, but I think the “quiet” kernel argument limits the output to the console:

How can I disable or remove the default “quiet” argument?

Hi @hordur ,

Welcome back to the community. :wave:

Probably the easiest way to achieve that would be to stop in U-Boot and enter the following:

setenv tdxargs "loglevel=7 earlycon"

If you want to keep it after reboot you can save the environment with:

saveenv

Hope this helps.

Best Regards
Kevin

Thanks for the very quick reply, that worked.

(however, the problem was not in the device tree, but some systemd unit that failed to start and caused the update to be mark as failed)
