Describe your issue:

…Hello everyone, sorry I’m bad at English. So my Voron is in canbus with an EBB SB2240. Until version 12.6 of Debian I had no problem. Since version 12.7 no more connection with mainsail. If I place the RPI 5 SD card which is under Debian 12.7 on an RPI 4, everything works. In fact, if I am under version 12.6 it works but not in version 12.7. Sorry if I’m not in the right place to ask my question…

This is absolutely the right place.
Unfortunately, an answer is not so straight forward: someone with the right knowledge would need to analyze exactly this setup to determine where things are going wrong.

If I got you right, the problem arises only in the combination of a RPi 5 and Debian 12.7, correct?

Hello and thank you for answering me. Yes absolutely, the problem only occurs on the RPI 5. and debian 12.7
