And broken it is.

I found out I had many SPI CRC2 errors in my kernel logs.
Looking around I found this post

It turns out the stock image 20220412.0 for nodered actually ships with the broken revision 1.108 of the kernel module.
Thanks to @knebb 's instructions I was able to downgrade to v1.106 and my neuron seems to be working fine again.

I hope someone from the customer support gets to see this post and fixes the image quickly.
Guys, you have a terrific product line (I bought two neurons and some accessories over the years and I am a very happy customer), but you should really improve the regression testing before releasing: it is not the first time I have problems when trying to use an official image: see here

I might be able to provide you with some logs in case you need help in troubleshooting on older hardware (S103 S/N 109 from 2017): just contact me in the next couple of days - then I'll have to put the system back on the field.

Quick update:

I repeated the Evok installation as per the instructions above on a clean vanilla raspbian stretch image taken from the official raspberry pi repo (not the UniPi customized one) and everything works fine.

Thus - there seems to be some misconfiguration in the official UniPi image, at least when used with M203: beware.

@tomas_hora Hi,
I did a fresh Rasbian install, got the neuron online, did a
git clone http.....
set the permissions (as per the GIT page)
started it up.
and....

PERFECT!

I have my python monitoring program starting automatically as a service, and I had to put a little sleep command in it on start as it was trying to run before EVOK started. Runs great.

Many thanks.
Merv.
