Reset during print Part 2 - Duet 3.1.1 / 3.2beta3 - Duet3+SBC

Via

@dc42 Thank you.

Config attached, not been changed from assertation failure (or from 3.1.1). No filament monitors.

Via

@dc42 any update on this?

dc42

I wasn't able to pin this down, except to say that it looks like random memory failure or corruption. Please upgrade to 3.4beta4. If it happens again, please post the print file and config.g if you haven't already (I'm using a tablet, so I can't tell), also daemon.g if you are using it.

@dc42 Failed again on beta4 (M122 at bottom) they are posted already but will group together here.

Thanks for your new report. I am fairly certain that the memory protection fault was caused by a hardware error, because there is no way that the instruction at that address should fault, nor any way that the faulting address should be zero. So I suggest we swap your board. Who did you purchase it from?

Via

@dc42 thanks for your time looking into this. Purchase was from E3D but I have just gone over the 6 months now (purchased 13th May), will you be able to authorise warranty replacement as reported prior?

dc42

Yes I approve a warranty replacement.

Via

@dc42 Thank you, will get in touch with E3D. Many thanks for your help.

dc42

@Via, two more things to try:

Try the new binary at https://www.dropbox.com/sh/tehhdvunh0pgr7q/AADgJ4Qj7W18MYaRRNNDdhpwa?dl=0, although I think it likely that it won't make any difference.
Your MCU temperature may be a little high, depending on how accurate the 39.4C reading is. 40C is well within limits, but the actual temperature could be higher. Please try powering up the board when it is cold and immediately run M122 to check the temperature reading. That will allow you to calibrate the MCU temperature sensor. See https://duet3d.dozuki.com/Wiki/Calibrating_the_CPU_temperature.

@dc42 MCU was over reading by ~2C so adjusted to compensate and showing ~35C now.

Installed new firmware and...

30/11/2020, 13:26:02	Finished printing file 0:/gcodes/[PLA] CFFFP_Top - ReRender - zero temps.gcode, print time was 1h 41m

So looked promising so without changing anything I reran print to make sure it was not a fluke and sure enough it was ...

Thanks, please go ahead with the warranty exchange.

@dc42 received replacement board from E3D today and working as expected in standalone, will get round to putting SBC back in this week but happy there shouldn't be any further issues.

Thank's again to yourself and @chrishamm for the help

@dc42 is there a way to properly "flush" the memory on thoses boards ?
I have been working on that issue for couples of weeks now on different setups and boards configuration and it seem to happen more and more often on most of them. I wonder if it could be caused by a bad sector or a bug and because of that spot it just happen more and more. (Sorry for my english here, Im french .. trying to explain clairly..)

Everytime I update/flash the firmware it seem to crash faster too.

At the moment Im down to testing different sd cards, maybe I got some fakes/cheaper cards causing the issue too.

Also important point: the setups I have who never been updated (some benchmarks and extruders tester) dont have that issue. Yet..
