Reboots/crashes - RRF ≤3.5.0-rc1

[Exerqtor]

@NeoDue said in Reboots/crashes - RRF 3.5.0-rc1:

@Exerqtor may I ask about the computer you ran Chrome on in that test? Which OS? Notebook or Desktop? Screensaver, sleep or hibernation / energy saving mode enabled or disabled? Unless I overlook something, one of these things probably made the difference here.

It's on a desktop running windows 10 pro x64, hibernation/powersaving has been turned off since i'm running these tests.

So it's eiter chrome thats making the issues OR both. That we will see if it crashes with only Orca Slicer running (as it is now).

---

@dc42 So i just came home, and it's been no crashes since 05:50 this morning at least, this is with only Orca Slicer open. Gonna let it stay idle like this until tomorrow morning and see what happens. But i got a sneaking feeling Orca Slicer (by itself at least) ain't the cause of the crashes.

[dc42]

@Exerqtor have you ever seen this issue when running DuetWiFiServer 1.27? If you haven't, or you are not sure, please try it.

[Exerqtor]

@dc42 Not sure, but i'm pretty sure it came after moving from 1.27. I'll revert to it now, shouldn't be an issue to run 1.27 with 3.5x on everything else?

[T3P3Tony]

@Exerqtor you can use 1.27 with 3.5x

[Exerqtor]

Ok, with that it's now on WiFiServer 1.27, and i'm back to having two tabs with chrome and one Orca Slicer instance (since that seem to be what made it crash most often). #waitinggame

@T3P3Tony & @dc42 Just had a crash on WiFiServer 1. 27 as well:

[NeoDue]

@Exerqtor thanks! Let me add my observations in detail, maybe they do help someone here - I honestly don't know what happens in detail when the browser is open on a "sleeping" computer:

1. Desktop PC running MX Linux or Linux Mint with Vivaldi open and no kind of powersaving except turning the monitor off active: dwc tabs do not crash, Duet does not crash.
2. Notebook (in my case an old MacBook Air) running Windows 10 x64 with the same Vivaldi version active, hibernation turned off, but higher sleep modes active: tabs with DWC frequently do not recover if the computer is woken from sleep. Duet crashes occur (on a Duet 3 6HC running RRF 3.5.0 beta 4 or 3.5.0rc1), but not every time the browser tab crashes. Several browser tab crashes seem to increase the risk for the Duet itself crashing however, as far as I remember.

I still have my old printer here which runs on a Duet 2 Wifi with RRF 3.3 or an early 3.4 version. If it helps anyone, I could try to recreate those crashes in the new board and then check if the old one might be affected as well.

[Exerqtor]

@NeoDue Interested in seeing if you're also able to recreate this on your setup with the same results!

Otherwise it's another crash over the night, same test criteria as the last report:

[T3P3Tony]

@NeoDue thanks for this information. We need the M122 report(s) for when the Duet crashes. The DWC not recovering from sleep modes etc may be related but may also be a different issue so lets leave that aside for now and focus on what happens when RRF crashes.

[NeoDue]

@T3P3Tony @Exerqtor okay. Just to be sure: This means I let the Duet crash and get an M122 afterwards. Anything I need to set on the Duet in advance?

[T3P3Tony]

@NeoDue It does not hurt to grab a M122 before you start but nothing specifically in advance.

[Exerqtor]

Just got back home from work, to another crash on 1.27.

Besides crashing (seemingly just as often as the 2.4 betas), DWC loads sooooo damned slow with 1.27!

Anywho, another report:

@dc42
I was looking at the code and found your ocmment about the failed assert.

// Look at the response
#if SAME5x	//TEMP DEBUG
	CheckStackValue(9, ra);			//***** This is the check that occasionally fails ******
#endif

looking backwards from here it will reset the spi and disable the dma channel. There is a comment about the disabling of the dma channel on SAME5x.

// Disable a channel. Also clears its status and disables its interrupts.
// On the SAME5x it is sometimes impossible to disable a channel. So we now return true if disabling it succeeded, false it it is still enabled.
bool DmacManager::DisableChannel(const uint8_t channel) noexcept
{

but the return value is not checked in the function:

static inline void spi_rx_dma_disable() noexcept

From here I've looked in the datasheet of the chip to check the dma function and found the following:

So it is possible that a DMA transfer is already scheduled but not processed and this will block/prevent the gracefull disable from taking place.

#endif

looking backwards from here it will reset the spi and disable the dma channel. There is a comment about the disabling of the dma channel on SAME5x.

// Disable a channel. Also clears its status and disables its interrupts.
// On the SAME5x it is sometimes impossible to disable a channel. So we now return true if disabling it succeeded, false it it is still enabled.
bool DmacManager::DisableChannel(const uint8_t channel) noexcept
{

but the return value is not checked in the function:

static inline void spi_rx_dma_disable() noexcept

From here I've looked in the datasheet of the chip to check the dma function and found the following:

So it is possible that a DMA transfer is already scheduled but not processed and this will block/prevent the gracefull disable from taking place.

Woah, great catch! Hope you're on to something there!

@T3P3Tony thanks! Test is running now. One thing I found due to the browser updating itself soon after start: when the browser was closed for update with Duet tabs open, there is a brief "incomplete transfer" message on the PanelDue - and then the Duet resets the wifi connection (3.5.0rc1 with wifi module firmware 2.1b6 - at least reconnection seems reliable now with that firmware version). After that, one of the Duet tabs was dead. The only thing that differed in the log was the amount of reconnections.

I will ignore that for now as you suggested and wait for a crash to happen. The printer is set to write an m122 log into a file afer every reboot - let's see what I find tomorrow.

[Exerqtor]

@NeoDue
Looking forrward to seeing how this turns out for you, and if we have the same root cause for the crashes!

---

Other than that i'm moving over to WiFiServer 2.1b4 again, 1.27 is pretty much useless at this point. It flip out on reboot/crash and won't connect to the LAN with the only means i've found to connect it when that happens is to power toggle the printer til it manages to connect. And once it's finally able to connect, connecting to the printer/DWC is a total shitstorm, 90% of the times it just yields a white/blank screen. And once you're finally able to get a connection it's soooooo slow.

Here is the last crash report from 1.27 and a snipet from the debug log so you can see how it behaves when not being able to connect to the LAN (attached as a mega.nz file since it's a shit ton of data).

The debug log file.

[NeoDue]

@Exerqtor so far no crashes here. They happened less often than they seemed to do at your place, so I will leave the test running.

I would however suggest you try to switch to Wifi firmware 2.1b6 instead of b4 - apart from debugging my config and macro files, that was the only thing I did with my printer since RC1 came out, and at least for me, that one solved some issues (albeit seemingly unrelated ones, but who knows...)

That's good to hear, on your behalf i mean

Oh is there a 2.1b6? And where is that bugger hiding out?

Otherwise it's been two crashes while on 2.1b4, and here is a report:

@NeoDue said in Reboots/crashes - RRF 3.5.0-rc1:

Duet crashes occur (on a Duet 3 6HC running RRF 3.5.0 beta 4 or 3.5.0rc1)

Is this when using the optional WiFi module for the 6HC, or using Ethernet? Do you have any M122 reports from the 6HC taken after the Duet has reset?

[NeoDue]

@dc42 That was all with the optional Wifi module active, I used that one from the very start with the 3 6HC.
Sorry, but I did not keep any M122 logs of that since I did not make the connection you and Exerqtor dug out here and simply thought: "random crashs... well, still beta - the Duet team will surely work an that already - and until you can find some trigger, there is no use in reporting anything".

@Exerqtor beta 6 is in the corresponding Github archive from the Duet team: https://github.com/Duet3D/WiFiSocketServerRTOS/releases
