Any idea why this RasPi does not get any WU?

I'd suggest you check the messages in the Event Log to see what responses it's getting when contacting the Scheduler.

Any idea why this RasPi does not get any WU?

Do you have the 32 bit libraries installed?

---

A proud member of the OFA (Old Farts Association)

I would have liked to get my Jetson SoC's running on Universe but alas there are no 32 bit libraries available in the Nvidia L4T distros. I could change them over to a normal Linux distro like Ubuntu but I would lose the standard Nvidia CUDA development installation that allows me to use the Nvidia gpus at Einstein where they are quite productive.

Both my Jetsons crunch Universe and run L4T (the 4GB model upgraded to 20.04.6 LTS with Glibc 2.31). I got some warnings installing 32-bit libraries, but it is workable.
The 2GB model even has a both OpenCL and CUDA capable GPU, but still runs on 18.04.6 LTS and has Glibc 2.27

Where did you find the 32bit libraries in L4T?
I have a Nano 4GB original and a 4GB TX2-NX both running the L4T based on 18.04.6 LTS and I just get messages that any 32bit library is unavailable in the distro.

Have you in the cc_config.xml :

<options>
<alt_platform>arm-unknown-linux-gnueabihf</alt_platform>
</options>

My guess is that when you check your sources list (/etc/apt/sources.list.d/nvidia-l4t-apt-source.list) that you see

deb https://repo.download.nvidia.com/jetson/common r32.4 main
deb https://repo.download.nvidia.com/jetson/t210 r32.4 main

edit that (as super user/with root access) so it looks like

deb https://repo.download.nvidia.com/jetson/common r32.4 main contrib non-free
deb https://repo.download.nvidia.com/jetson/t210 r32.4 main contrib non-free

then do a

sudo apt update --fix-missing
sudo apt dist-upgrade

then do a

sudo dpkg --add-architecture armhf
sudo apt update --fix-missing
sudo apt install libc6:armhf libstdc++6:armhf zlib1g:armhf libfuse2:armhf libgomp1:armhf libboinc7:armhf

to be really sure you get all 32-bit apps from all projects, edit you cc_config.xml to have both these lines

<cc_config>
    <options>
        <alt_platform>arm-unknown-linux-gnueabihf</alt_platform>
        <alt_platform>armv7l-unknown-linux-gnueabihf</alt_platform>
    </options>
</cc_config>

If you want work for projects that have real old apps, you can also add a third line:
<alt_platform>armv6l-unknown-linux-gnueabihf</alt_platform>

Still no luck with your suggestions.

Bizar. I have my Jetson Xavier NX working now too with the exact same approach -and the exact same error messages in the beginning. Try rebooting between the steps.

Your link points to a host with 0.10 RAC. You are surely confused about ARM performance

The errors point to having just 'main' is the sources. Either you haven't edited those two lines, or you edited 'starred-out' lines -having no effect.
Do all as I suggested, verbatim, and in the right sequence.

If you don't trust it: take out your SD card, put in a new one with the latest jetpack image for the Jetson Nano or TX and try with that.
If all works well, think about running the Jetson straight from SSD via USB 3.0

No it doesn't work here.

Moot point now that Universe is shut down for 3 months. May never come back.

First things first!

First step 1: sudo dpkg --add-architecture armfh

Then step 2: sudo apt update --fix-missing

only thereafter can you do

Step 3: sudo apt install libc6:armhf libstdc++6:armhf zlib1g:armhf libfuse2:armhf libgomp1:armhf libboinc7:armhf

I myself am presently re-doing these steps as my fallback project -SiDock@Home- has stiffer requirements and my 4GB Nano seems to be missing libgomp1:armhf.

My 2GB model can't even run SiDock: its 18.04 L4T has glibc 2.27, too low for SiDock

/lib/arm-linux-gnueabihf/libc.so.6: version `GLIBC_2.28' not found (required by ../../projects/www.sidock.si_sidock/cmdock-s_wrapper_2.02_arm-unknown-linux-gnueabihf)

Instead of 'contrib' and 'non-free' you can better use 'restricted' and 'universe' in case of L4T...I have the 4GB model working now at SiDock, but it was quite a struggle to get all 32-bit libraries.

BTW: I received Universe WUs for the 4GB model over the last three days (1, 2 and 3 February 2024). Not many but it might be a sign that the 'dry spell' will not last forever.

In the news they announced no new work for 2-3 months. The only work coming out now are resends- it will take about 1.5-2 months for all existing work to finally be completed.

I followed your post https://universeathome.pl/universe/forum_thread.php?id=680&postid=6394 verbatim
Adding the architecture right off the bat produces the errors. That is before I tried to add the armhf libraries which produce further errors.

Tried with restricted and universe. Same difference. No luck.

Skipping acquire of configured file 'main/binary-armhf/Packages' as repository 'https://repo.download.nvidia.com/jetson/common r32.7 InRelease' doesn't support architecture 'armhf'
W: Skipping acquire of configured file 'restricted/binary-arm64/Packages' as repository 'https://repo.download.nvidia.com/jetson/common r32.7 InRelease' doesn't have the component 'restricted' (component misspelt in sources.list?)
