Nvidia Jetson Orin Nano Super Flash

[SuperElectron]

ISSUE

I run the installation instruction for kairos on a Nvidia Jetson Orin Nano Super and it fails.

• https://kairos.io/docs/installation/nvidia_agx_orin/

This is where the error comes from:

IMAGE=quay.io/kairos/ubuntu:22.04-core-arm64-nvidia-jetson-agx-orin-master
docker run --privileged \
        -e container_image=$IMAGE \
        -e STATE_SIZE="25500" \
        -e RECOVERY_SIZE="21000" \
        -e DEFAULT_ACTIVE_SIZE="7000" \
        -v $PWD/bootloader:/bootloader --entrypoint /prepare_nvidia_orin_images.sh -ti --rm quay.io/kairos/auroraboot:v0.6.4


mv: cannot stat '/tmp/arm-builder.1GeWgiEsAO/tmpefi/EFI/BOOT/*pf2': No such file or directory

And I traced the error back to this script:

• https://github.com/kairos-io/AuroraBoot/blob/main/image-assets/prepare_nvidia_orin_images.sh#L43

Script to Replicate the Issue

I have created a script from the docs

• note I am using "personal" not "business" which means I use quay.io/kairos/auroraboot:v0.6.4 below

The Error happens at # >>>>>>>>>>>>>>> ERRORS OUT in the script below.

I am happy to help with a little bit of direction, if needed.

@SuperElectron mh that's weird but maybe there is a bug as we moved some grub settings across packages.

@SuperElectron can you try to edit the jetson nano script to cp -rf /arm/raw/grubartifacts/grub2/*.pf2 $WORKDIR/tmpefi/EFI/BOOT/fonts instead of mv $WORKDIR/tmpefi/EFI/BOOT/*pf2 $WORKDIR/tmpefi/EFI/BOOT/fonts , re-build the auroraboot image and report back ? Thanks!
