What we know so far:

This issue only affects Duet 3 Mini WiFi and only in standalone mode with WiFi enabled
The symptom is that the machine resets. This can happen either during a print or when the machine is idle.
A subsequent M122 report shows the reset reason as Hard Fault and that the Network task was active at the time. The fault is usually reported as imprecise unless a particular configuration command has been used to disable write buffering (see later).
It only occurs when there is are least one instance of Duet Web Control communicating with the Duet
A number of users have now reported it, however none of us at Duet3D have been able to reproduce it. So it likely depends on machine configuration, or network configuration, or browser or DWC configuration, or processor silicon revision.
My previous investigations aided by a one user (thanks Exequtor!), strongly suggest that it is not caused by a firmware bug, but likely caused by a chip-level issue with the DMA controller. Therefore I need to find a workaround to the issue rather than just find a software bug.

If any of you experience this issue and would like to help me to find a solution, please do the following:

Make sure you are running firmware 3.5.3 or 3.6.0-beta.1. These are the only firmware versions I will be working with.
Add the following command to your config.g file:

M122 P500 S0

This command disables write buffering in the CPU. It has the effect of making the Hard Fault precise so that the diagnostic data is more useful, at the cost of reducing performance slightly.

After performing #2 above and rebooting, any time the fault appears run M122 afterwards and post the result in this thread. Also post your config.g file.
Perform the following - note that comments starting with <---- are instructions to help you, not part of the command to be entered.

Send M122 P106. Example response:

m122p106
Platform 2001d138-2001e737
SbcInterface 2001e740-2001ea70
Network 2001ea80-2001eb67      <--------------- take the first of these two values, in this case 2001ea80
GCodes 2001eb70-2001ff6f
Move 20023ff8-20024d33
Heat 20025110-20025237
PrintMonitor 20025240-2002544f
FansManager 20025458-200254d7
PortControl 200254e0-2002550f
Display 20025518-20025533
ExpansionManager 20025540-200282f7

Send M122 P1007 A{0x########+8} where ######## is the first hex value in the Network line of the previous response. Example response:

m122p1007 a{0x2001ea80+8}      <----------- put the value from the previous response between the 0x and the +8}
2001ea88: 2002c420             <----------- take the second value reported here, in this case 2002c420 (your value may be different)

Send M122 P1007 A{0x########+136} where ######## is the second number in that response. Example response:

m122p1007 a{0x2002c420+136}    <----------- put the value from the previous response between the 0x and the +138}
2002c4a8: 20032dd0             <----------- the second value reported here is the value I need, in this case 20032dd0

Copy the transcript of this sequence from DWC and post it here along with your M122 report showing the Hard Fault.

@dc42 In one of the earlier threads I reported having this issue on RRF 3.5.3.
I now temporarily swapped my Mini5+ WiFi for a 6HC since I have a project due.
I'd be happy to lend out my Mini WiFi if that would help you to eg. reproduce the issue and find a solution?

dc42

@Maurits that may help if you include the SD card so that I can boot it with exactly the same configuration. Which country are you in?

Maurits

@dc42 I'm located in the Netherlands and of course I'll provide the board including SD card. Please contac met via email or other non-public way to make futher arrangements.

@dc42 Thanks for investigating this further. It's really the last couple of days there was no error. Today I started to print and wanted to turn WiFi of, just to be sure. I encountered this error:

If anyone who experiences this issue would like to help track down this issue, I have put a build of RRR 3.5.3 for the Duet 3 Mini with extra debugging info at https://www.dropbox.com/scl/fo/vp24fllwuua9yejr8pej1/ANRHyUhbMU5DRTJBNeF1sKg?rlkey=97mm1rpm4h0m22bjalgxmrrwq&dl=0. Please install this, connect a PC running a terminal emulator to the USB port, and leave it running with at least one DWC session connected to it. If you see any "Memory difference" messages on the terminal then please report them here, and if you get any resets then please post a M122 report.

omtek

@dc42 Build installed and running.

and I've logged a message in the console already:

*** Memory difference at offset 24: was a5a5a5a5 now 00000000

That was the final message in the console before the reset. The printer was idle. DWC was open in Chrome.

~~No reset to report.~~

@omtek thanks for your feedback. Please continue to report any instances of this message and resets (whether associated with a debug message or not).

Please note, if you are using YAT on a PC as the terminal emulator, then after any reset of the Duet you need to tell YAT to disconnect and then reconnect. Older versions of YAT used to reconnect automatically, but sadly the current version does not.

FWIW I have been running this and similar debug builds since the start of this week, and I have seen messages giving memory differences at offsets 32, 24 and 16 although in most cases they did not result in a reset.

omtek

@dc42 Logged another message. Printer was idle at the time, and this was the first memory difference message since my last post. There haven't been any resets since my last post, either.

*** Memory difference at offset 20: was 2001ea80 now 00000000

omtek

Had another reset this morning. I didn't record any additional memory difference messages. The printer was sitting idle, cooling down after completing a print about 35-40 minutes prior.

@omtek thanks again. Based on your results and some messages from my own system, I have built up a picture of what is happening.

@omtek @Exerqtor @wschadow @Maurits @Inlinebrother please install the new 3.5.3 debug firmware that I have just put at https://www.dropbox.com/scl/fo/vp24fllwuua9yejr8pej1/ANRHyUhbMU5DRTJBNeF1sKg?rlkey=97mm1rpm4h0m22bjalgxmrrwq&dl=0. Like the previous version, this will print a debug message to USB when it detects that something is amiss. This build also attempts to recover from the situation in order to avoid a reset.

As before, please leave this running on your machine with a PC running a terminal emulator connected to the Duet USB port, and at least one instance of DWC connected to it via WiFi. Please report any "Memory difference" messages appearing on that terminal, also the M122 report if you are unlucky enough to have a reset.

Based on your reports and any further messages that my own system produces, I will evaluate whether this code with the debug removed can form the basis of a solution to this annoying issue.

omtek

@dc42 Logged a memory difference message with the new build. Printer was idle. No reset as of yet.

*** Memory difference at line 2228 offset 12: original 0d0a0d39 copy 20032958, original changed, copy ok, fix=yes

Logged another memory difference message. Still no reset.

*** Memory difference at line 2228 offset 60: original 2001882c copy 0d0a0d39, original ok, copy changed, fix=no

Exerqtor

@dc42 Haven't had time to look at this before now (like I mentioned in the email), but do you have a debug version based on 3.6 as well?

dc42

@Exerqtor I'll prepare a 3.6 version with the debug in it today.

dc42

@Exerqtor I've put a 3.6.0-beta.1+debug build for the Duet 3 Mini at https://www.dropbox.com/scl/fo/01s6pikmcusa2e3vu0rkh/APdYxDkXDSIWqeQl0R__Gag?rlkey=iwd3zb2dk3ggjw7ihcy2whg5h&dl=0. The instructions are slightly different from the 3.5.3 version:

Install it
Preferably, connect a PC running a terminal emulator to the USB port, check it is communicating with the Duet, and execute M111 P8 S1 to enable debug messages
Leave it running with at least one DWC session connected
Report any "Mem diff" messages that are displayed on the terminal emulator
If you get any unexpected resets, post a M122 report

If you don't wish to connect a terminal emulator, then don't run M111 P8 S1 and it won't attempt to output the debug messages to USB. It will still log up to 4 memory difference reports internally, but only if the board doesn't reset. Running M122 will report these messages just before the "Storage" section of the report, and clear them.

dc42

@omtek thanks, that's useful information. The first memory difference would likely have resulted in a reset in previous firmware versions, but the memory check detected and fixed it. The second memory difference was harmless.

Exerqtor

@omtek said in Random Hard Fault resets on Duet 3 Mini WiFi:

@dc42 Logged a memory difference message with the new build. Printer was idle. No reset as of yet.

Out of curiosity, how long had you had the logging going before it threw these messages?
