3.4.0 beta4 troubles

PetrKroupa

Two things happened after I uploaded 3.4.0 beta4 today. Previously with beta3 okay.

My config duet3 6HC + 1LC, SBC Pi4

When upgrading, the terminal asks if you want to upgrade the tool board. YES. It went without a error. But after the reboot when I check the M122 b121 the version was still the original (beta3). M997 B121 and then everything is OK.
after about 2 hours of printing, my filament was jamed (90% GCODE done). Magnetic sensor paused print, no problem. I corrected the error on the spool, moved the filament back and forth a few times and pressed the resume. The extruder moved to the place where printing was interrupted and nothing happened for about 5 seconds. Then the printer decided to make it home again, and it looked like GCODE had started from begin. Unfortunately, I couldn't research it anymore because I had to use the emergence button to avoid big crash.

I will try to repeat it and document more.

I tested again and happend again. Same problem. Print will restart from beginnig. It can also be seen in the percentage that is done. It starts from the beginning. Just press pause and resume. It also starts from the beginning. Something is wrong ...

I have just tested this and could not recreate the issue, going from 3.4b3 to 3.4b4. that said I did find that the firmware updates took longer than the apt command gave them to finish which may be the cause of the problem so I have reported it to @chrishamm.

Now looking at the second part of your report.

@petrkroupa Yes i can reproduce an issue with pause on my toolchanger using 3.4b4 in SBC mode. Thanks for reporting this.

@petrkroupa and @leobg This issue should be fixed in b5

@t3p3tony I can confim, in beta5 pause\resume work with no problem. And update from b4 to b5 with no problem. Tool board was updated during update proces. Good work!
