When removing mono and then reinstalling, you see all kinds of information.
Among that output you must see lines saying it is recompiling something.

Based on wikipedia, Pi1 and Pi zero use the same cpu, so there really should not be problems regarding that detail, because afaik there are several users of pi zero here. Of course there is a small possibility that the problem is related only to the newest builds and we haven’t figured that out yet… but not very likely imho.

That output suggests that it did not recompile anything, unless it is happening on the ”setting up” phase and not shown on screen. So this did not solve your crash? I wonder if the package manager does something stupid when it is reinstalling a package that is already cached on system. You could use

sudo apt purge mono-complete
sudo apt autoclean

before reinstalling and see if there is a difference.

Is this a clue?

Code: Select all

System.OutOfMemoryException:.ctor
(from the log in the previous post - although I had seen it in an earlier post but forgot to comment!)

Only idea I have left is that you could try running a little older build of cumulus. You don’t need a full reinstall, just unzip an older version over the current one.

That could be a good catch. The earliest pi1:s have had only 256MB of memory, and probably that won’t be enough. If it is a 512MB model, I would chevk how much memory is allocated to gpu and tweak it as low as posdible. Also stopping unnecessary services could be worth a try.

Ah... out of memory. Could be yes.
It could also be useful to increase swap space to 2*<physical mem>

Thanks to everyone that has tried to help.

I tried changing the swap file, but still not difference.

I gave up and installed Raspberry PI OS Lite and then followed the instruction in the pinned post for installing cumulusmx and that has worked fine.

I suspect it is me using a very basic pi to try to run it and the image not playing nicely

That would make sense as the 'desktop' version of 'BULLSEYE' would have many other processes running = which aren't needed for running CumulusMX.

Glad to see you got it running !

Other explanation could also be that the image does have some other packages (besides mono), that would need reinstall to work properly on armv6.

I’m also glad that it is sorted now. Just have to remember this if some other user also hits the brick wall with the image on old pi or pi zero. :lol:
