Can only find guides and howtos related to modifying /boot/extlinux.conf, but there is no such file on my xavier nx once flashed. for info I am not working from the sdkmanager but building a Yocto image based on meta-tegra. is this related to JP now flashing an EFI image rather than a cboot based one?
If you are talking about jetpack5, then there is no Cboot. Directly using UEFI.
And it is not /boot/extlinux.conf. It is /boot/extlinux/extlinux.conf
Indeed, have to replace a dtbo file and it’s proving to be a nightmare. Any clue greatly appreciated as yocto don’t deal with binary patches so the usual
devtool extract
git commit
git format-patch
Will not work
So not sure how to replace the content of that dtbo
The dtbo on a rel-35 device won’t take effect by using extlinux.conf.
Dtbo is put inside the board config as field “OVERLAY_DTB_FILE=” and got updated by flashing.
Please see add dtbo file to xavier nx kirkstone branch (efi boot) · OE4T/meta-tegra · Discussion #1635 · GitHub for a more complete description of the entire issue.
