Reboots/resets randomly - RRF 3.5.0-b4

dc42

@Exerqtor that's interesting, it's not the same crash as before but it is the same task (NETW) and probably the same area of code.

If your machine is not being used, please can you do a couple of things to increase the load on it, in the hope that this will make the problem occur more frequently. In particular, try these:

In the DWC Machine Specific config, reduce the polling interval e.g. to 100ms
Reduce the lengths of G4 delay commands that you have in daemon.g.

Exerqtor

@dc42
Guess that's somewhat positive and it would help narrow down the search a little? wishfull thinking

Ok I've set the "Communication update invervals" to 100ms now (if that's the one you were refering to).
What do you suggest changing the daemon.g delay to? It's currently 1second, so reduce it to 300ms or something maybe?

dc42

@Exerqtor I suggest you try 100ms. If that makes the response to console commands such as M122 excessively slow, increase it.

Exerqtor

@dc42
Ok, then both have been set to 100ms. Now it's just to wait for a crash i guess

Exerqtor

@dc42
Don't look like the added stress we were able to muster up with those changes did much, only had one crash since they were changed:

@dc42 Have you had any more time or luck with this David?

Mine havent had any news crashes sunday, and been sitting idle since then since it quite frankly ain't stable enough to be used for any duration of time

dc42

@Exerqtor unfortunately I haven't been able to reproduce it.

Exerqtor

@dc42
Haven't had any more crashes here either, though the printer has just been sitting idle since last time it happened.

dc42

@Exerqtor I'm wondering whether it could possibly be a hardware issue, because I haven't been able to reproduce it and nobody else has reported it. Which country are you in and which Duet3D reseller do you use?

Exerqtor

@dc42
Might be the case, this perticular board ain't a original duet3 board but a Fysetc "Big Dipper" (killed the processor on my Duet 2 so I needed a subsitute board ASAP, and couldn't justify cashing out for a original duet 3 mini & addon board to the mrs 🤦‍♂️).

It haven't had a single crash since the last one i reportet two weeks ago though. Even with the extra load we added.

Just started a 2.3hr print on it now to see if it wil act up again.

droftarts

@Exerqtor Please be up-front about using clone Duet boards. It would save a lot of time supporting, and trying to resolve issues with, boards who's quality are beyond the scope of what Duet3D can control.

Regarding the Fysetc Big Dipper board, when the TeamGloomy devs took a look at it, they weren't that impressed. When looking at the schematics, it doesn't include as much filtering, and some other corners have been cut, compared to the Duet 3D Mini 5+.

Ian

dc42

@Exerqtor as I haven't been able to reproduce it, and nobody else has reported it, and it's a clone board, I'll park this issue unless/until someone else reports a similar issue.

The SAME54P20A processor we use in the Duet 3 Mini has been almost impossible to purchase for the last two years, so I wouldn't rule out the possibility that the clone boards use reject/remarked chips.

Exerqtor

@droftarts It wasn't like I was actively trying to withold any info in that regard. Since it was a non-issue before the specific FW update I didn't even think about it possibly being and HW issue given the circumstances.

I'm in no way doubtfull of the original duets being of way superior quality all across the board, but the circumstances simply didn't allow for it when I had to replace the board i killed.

@dc42 Yeah I haven't had any more issues myself either (knock on wood) so I have no idea what was happening.

And just to be clear, I didn't mean or try to gasslight anyone with not specifying it being a clone board since I assumed it to "simply" being a FW issue introduced to the beta in question.

Exerqtor

@Exerqtor
Just checked the printer and saw it had crashed again, about 30min after the job from yesterday was finished.

Heres the M122 in case it might shine some new light on it 🤷‍♂️

dc42

@Exerqtor that's a different crash from the previous ones but probably in the same area. Looks like a similar cause: a few stack words have been cleared to zeros during a DMA transfer between the WiFi module and the main processor.

The only thing I can suggest (and it's a long shot) is to try reducing the SPI clock speed of transfers between the WiFi module and the main processor. You can do this by sending:

M589 L{0x3002}

M122 should then display the WiFi clock register as 00003002.

Exerqtor

@dc42
Interesting 😶

I'll try that later, is guess this something that needs to be done on every boot right (so I'll put it in config.g)?

dc42

@Exerqtor it won't work in config.g because the WiFi interface isn't enabled until config.g completes.

Exerqtor

@dc42 noted

droftarts

@Exerqtor if it is WiFi related as @dc42 suggests, I note you’re on WiFi firmware 2.2beta4 . Check you have the later version of this, as I think there was an issue with the early release of this. It might also be worth reverting to 1.27, in the RRF 3.4.5 release.

Ian

Exerqtor

@droftarts I'm pretty sure i installed the newest one once David found and patched the issue, but ofc. I can download and install the newest one avalible on git to make sure.

I'm trying to avoid rolling back, if possible (since i would much rather try to have it fixed). If my memory serves right I had no issues on 3.5b2 either, and these issues was introduced with beta 3.

Otherwise, i did a total of 12hours printing yesterday almost back to back without any issues. The printer however totally lost it's shit during the day today while idle 🤣

The fist of those crashes was with reduced SPI clock speeds, but the subsequent ones should be with default speed.

EDIT:

Just re-downloaded and installed the WifiServer from Release 3.5.0-beta.4 again. Lets see if it's any changes, I'm however 99,9% sure i allready had the latest release of it installed.
