Prints stopping mid print and duet rebooting.
-
That's the first time I've ever seen a software reset code of 0x70xx reported. Which firmware version are you running? Please upgrade to 1.18.1 if you are running an older version
-
Could we get firmware version in the M122 code? Would help for these M122 dumps.
-
I am already on 1.18.1, Is it worth reinstalling this version,? Is there anything else I can do? I initially thought it was a heat issue but these last 2 resets have happened within minutes of turning on the Printer and starting preheat of the bed so the CPU temp got to no more than 35c or so.
-
I suggest you reinstall 1.18.1 just in case a flash cell is not fully programmed.
Reset code 0x70xx indicates that a debug exception, SVCall or PendSV exception occurred. None of those should happen unless the firmware is corrupt, or the return stack has been corrupted. If the problem persists then I will change the firmware to give a stack dump for those exceptions like some other exceptions do. [Actually, I will probably do that anyway.]
-
Ok thanks I'll do that tonight.
-
Well I flashed the firmware but it is still resetting.

Do you think it might make a difference if I flash the firmware using Bossac rather than the web interface?
-
Well I have erased and reinstalled using Bossac and so far so good, Hope I don't jinx the print but it is halfway through a 2 hour print and is still going which is more than it has done for a while.
-
Well the print finished but when I went to upload a new file to print the Duet reset again.

That software reset code indicates that the firmware was stuck in a spin loop for too long, and although it was executing Move module code at the time, the network lock was active and the firmware was trying to do USB output. Have you accidentally enabled debugging? To check, run M111 with no parameters. It should report that debugging is off.
