SBC Freezing at RRF 3.2
-
What is the best way to find out why my Pi4 freezes after the 3.2 update? This did not happen during printing (there were only small prints).

What exactly freezes and when?
-
In terms of time, I cannot answer that when. The touch from the HDMI LCD no longer reacts and the SBC is also no longer in the WiFi.
Until now the printer has only been idle. -
If the screen just freezes and WiFi stops working, it could be the SD card. I'd try to replace it, preferrably with a new A1 or even A2 microSD card.
-
But when I use Firmware 3.1.1 on this sd card All ok and when I Upgrade to 3.2 freeze it.
But this night doun't freeze the SBC.

You could try setting up some logging.

I have exactly the same issues after upgrade to RRF 3.2. The unofficial 3.3 Beta works.
-
@gruen Are you saying 3.3 beta 2 resolves it?
-
@Phaedrux
I used unofficila-3.3beta from 2021.02.01 and "upgrade" to RRF3.2. Now I have sometimes this freezes. -
@gruen Try this release: https://github.com/Duet3D/RepRapFirmware/releases/tag/3.3beta2
