Backtrace show always same address. I tried older version of firmware but FluidNC crashed at same address
All files longer then 20 minutes of working
I think what you really mean is "all files longer than 20 minutes of working that I have tried". It would be nice to have an example of one such file so I don't have to guess.
As an example of what I mean by not knowing, I though of trying a single line like "G1 X250 F10" which would take 25 minutes. That might trigger the problem, but it seems unlikely. Nevertheless I am trying it.
The one-line command that takes 25 minutes did not crash. Please supply an example GCode program that does crash.
I have similar issues here with a Makerbase MKS DLC32 board. It crashes randomly. I would say, it started to happen since 3.8.0, maybe 3.8.1. Never had this issue with 3.7.x.
Can confirm, sadly no logs as I did downgrade and not saved them.
Playing gcode files -> random crash after 0-4 Hours (This could be caused by network environment, scans or unintended access)
Run gcode files and reload webui -> crash immediate (Lost SD-Card or full crash)
Have a simple move without running gcode and reload webui -> crash immediate (Lost SD-Card or full crash)
Can confirm this for 3.8.0 and 3.8.2
Not happens with 3.7.x as long as I can say, random crashes are hard to reproduce ^^
I made a lot of experiments and now can crash ESP with same "Backtrace: 0x40081bf4:0x3ffbf85c |<-CORRUPTED". For this I open FluidNC web ui then go to "FluidNC Settings" tab, then start any g code file from UGS and press "Manage local files". ESP always crash at 0x40081bf4:0x3ffbf85c.
Why its randomly? Possible FireFox try update some cashed pages even if tab closed.
With "Manage local files", the browser asks FluidNC for a list of FLASH files. That causes accesses to the FLASH filesystem, which interfere with the interrupt service routines (ISRs) that occur during GCode execution. We have tried and tried to ensure that all the code that can run from ISRs is "FLASH safe", but it is difficult to maintain that because the system, compiler, and the various third party libraries are so complex. We often think that we have found all the problem areas, but then a seemingly-unrelated change will cause a bit of unsafe code to creep back in to an ISR routine. I need to do another deep search. I have been putting it off because it is very tedious, boring work and there is other fun work that I have been doing instead.
