[3.5.0-rc.3] M122 causing Lost connection to Duet (Timeout

timschneider · 30 Jan 2024, 11:21

Duet MB6HC in SBC mode with 3.5.0-rc.3.

When sending M122 it sometimes triggers a bug, which is causing a Error: A task was canceled or StuckInSpinLoop, Gcodes spinning - don't know what's first.

How to reproduce:
Send consecutive M122 until the connection is pending ( it is sometimes triggered with the first M122, sometimes it takes 10 - 15 times)

Output of M122

@droftarts this is maybe for @dc42 as I guess it will stop in the output of the tasks list.

the Output of M122 in the eventlog will stop with the following:

ok now I'm pretty sure that this is the dead lock

 				const Mutex *m = Mutex::GetMutexList();
				while (m != nullptr)
				{
					if ((const void *)m == taskDetails.pvResource)
					{
						str.catf(" %s", m->GetName());
						break;
					}
				}

as there is a

 m = m->GetNext();

missing.

@timschneider Unsure whether or not this helps track anything down, but whilst debugging some networking issues I was having whilst using 3.5.0-rc.2 I noticed that I've got StuckInSpinLoop being reported by M122. Having not looked at the git diff between rc.2 and rc.3, I'm unsure whether the section you mention has had any changes that would also be present in rc.2. If not, disregard my comment as irrelevant.

@dc42 /@chrishamm

I can confirm this in SBC mode as well.

The First M122 i got had a "normal" response, the machine has been up for a while:

From the second M122 I got no response initially, then a system reset:

Note it appears to have lost two connectivity to two 1HCLs

this is the M122 response I got when i sent it after the system recovered from the reset

Also note how the reply looks like parts of 2 M122 replies mixed together at the start.

I did it again after a full board reboot and M122 did not report at all this time:

note i have a G0 S2 in config.g and normally do not get the errors on startup about boards 50 and 51

I've added corresponding issue and pull request on Github.
https://github.com/Duet3D/RepRapFirmware/pull/955

The Binary for MB6HC
Duet3Firmware_MB6HC.bin

That solved the problem for me.
