Fan runs on full on startup

Note that jetpack packages are not installed. You may try installing these.

Do you see any service having failed to start ?

sudo systemctl --failed

You may also try to reinstall bootloader with:

sudo dpkg-reconfigure nvidia-l4t-bootloader

If not enough, you may post the output of:

cat /etc/nv_boot_control.conf

That does sound like a problem.

Some packages could not be installed. This may mean that you have
requested an impossible situation or if you are using the unstable
distribution that some required packages have not yet been created

The following information may help to resolve the situation:

The following packages have unmet dependencies:

E: Unable to correct problems, you have held broken packages.

Upgrading the 9 packages does not solve anything, nor does running sudo apt install --fix-broken, or disc-upgrade, or any other command found in How to Install JetPack :: NVIDIA JetPack Documentation. Perhaps this is interesting:

I notice that the two final entries look like they should (“r35.1” rather than “35.1”), but what about the first two?

Edit: Haha, forgot to reply to everything except your first line. Here are the outputs.

Apparently installing Nvidia-container before installing jetpack makes jetpack weird. I fixed it, so now

 apt list  | grep jetpack

WARNING: apt does not have a stable CLI interface. Use with caution in scripts.

libnvidia-container0/stable,now 0.11.0+jetpack arm64 [installed]

Issue, however, remains, and above post is still correct (ie unable to reconfigure boot loader, no failed services, nv_boot_control.conf unchanged)

hello per.edwardsson,

Jetpack components should be included. could you please also share your full steps to flash AGX Orin. for example, we’re using SDK Manager for setting up development environment and flashing JetPack release image to the target.

Download the files secureboot_R35.1.0_aarch64.tbz2, Jetson_Linux_R35.1.0_aarch64.tbz2, Tegra_Linux_Sample-Root-Filesystem_R351.0_aarch64.tbz2. Untar them in the same folder, in my case ~/nvidia_flash. Since I have an SSD connected on the M2 connector, I would like to utilise that space. I am not sure I have done this step correctly, so feel free to feedback. I find the size of my M2 disk and enter that into the file ./tools/kernel_flash/flash_lft_nvme.xml, in row 2, setting sector_size and num_sectors to match my disk. I then do sudo ./apply_binaries.sh. I also did sudo ./tools/l4t_create_default_user.sh to create a user. I then perform the flashing in two steps. First, I run sudo ./tools/kernel_flash/l4t_initrd_flash.sh --no-flash -c tools/kernel_flash/flash_l4t_nvme.xml --external_device nvme0n1p1 --showlogs -S 450GiB jetson-agx-orin-devkit nvme0n1p1. After that completes, I replace --no-flash with --flash-only. Sometimes I have to retry once or twice before succeeding, which is why I split it up.

From now, fan is on. Any advice?
