Jetson Orin Nano serial console errors

[Lander0606]

I created an image for the Jetson Orin Nano (devkit) but in the serial console (debug) of the Jetson I'm stuck in a login loop. I get numerous amounts of login prompts until the maximum amount of login attempts is exceeded:

Also, when inserting an ethernet cable, I see no ip address being assigned to the board. Any idea how to solve these errors?

The firmware of the board is updated to version 36.4.2 be compatible with Jetpack 6.2 and the board is flashed with my image using initrd-flash. No errors occurred while flashing.

Build target: core-image-base
Yocto version: scarthgap
Storage device: SD card with rootfs device mmcblk0p1

Sounds like you're using stock poky... could you try building with INIT_MANAGER = "systemd" in your configuration? The L4T stuff is all produced by NVIDIA for systemd-based distros, and while we try to retrofit them for compatibility with sysvinit, it doesn't get tested very frequently.

Alternatively, you could try using our demo distro to get started. We build and test that regularly, using the demo-image-* recipes there.

I added systemd to the DISTRO_FEATURES in my local.conf (adding it in core-image-base didn't change anything), but now I get the following error when building:

ERROR: Nothing RPROVIDES 'udev' (but /home/landervl/yocto-tegra/poky/meta/recipes-core/packagegroups/packagegroup-core-boot.bb RDEPENDS on or otherwise requires it)
eudev RPROVIDES udev but was skipped: conflicting distro feature 'systemd' (in DISTRO_FEATURES)
systemd RPROVIDES udev but was skipped: missing required distro feature 'usrmerge' (not in DISTRO_FEATURES)

I followed the tutorial from RidgeRun to create a custom Linux distribution for the Jetson boards, so I just cloned poky and meta-tegra in a folder with the following local.conf additions:

MACHINE ?= "jetson-orin-nano-devkit"

DISTRO_FEATURES = "x11 opengl systemd"

IMAGE_CLASSES += "image_types_tegra"
IMAGE_FSTYPES = "tegraflash"

I then chose the core-image-base build target, but I'm starting to think that this tutorial isn't up to date anymore or things changed for the Jetson Orin Nano...

Do I need some extra layers in Yocto or other changes in my local.conf? Or are there maybe other (new) documentation pages to consult? I'm going to make a Linux operating system for the Jetson Orin Nano in the context of a master's thesis "Linux OS in Space", so this will involve stripping the current distribution and customizing the kernel.

but I'm starting to think that this tutorial isn't up to date anymore

I do think the page at https://developer.ridgerun.com/wiki/index.php/Yocto_Support_for_NVIDIA_Jetson_Platforms_-_Setting_up_Yocto is possibly out of date, but they did add a link there to tegra-demo-distro which is what I'd recommend for getting started (as Matt suggested) along with demo-image-base or similar image.

Once you have a working image there you can strip things out and/or compare to the base poky setup more easily.
