3.5b1 Reset reason: StuckInSpinLoop?

[Diamondback]

@dc42 Will se if I can get something to happen without all the dotstar LEDs and stuff. If I can, I will also test 3.4.5, but since the main work here is related to an 8x8 dotstar display, I can't easily run that without the custom array stuff.
I will see what happens.

[dc42]

@Diamondback no need to test 3.4.5.

The odd thing is that the M122 report indicates that the MAIN task is running, but the stack trace reports that the IDLE task is running. These two are not consistent.

[Diamondback]

@dc42 So, when I increase the frequency of the endless loop iterations, the issue certainly happens quicker. It also only appears to happen when I use my 8x8 dotstar grid code, but not when I directly control the dotstars with just very simple code.

I'll try to minimize the needed code as much as possible, but my guess atm would be something to do with the arrays I use.

[dc42]

@Diamondback a few more M122 reports after unexpected resets may be useful too.

You could also test whether reducing the DWC polling interval provokes the problem more quickly.

[Diamondback]

@dc42 Alright, so far I have not been successful at replicating it at will, sometimes it happens five times in a row just seconds after starting the board, sometimes things work fine seemingly forever.
Will continue to test and get more M122.

[dc42]

@Diamondback in that case it's probably an interaction between different tasks that's provoking the problem. Try reducing the DWC polling interval and/or having several instances of DWC attached.

[Diamondback]

@dc42 some more M122, I think I figured out why it didn't want to crash anymore yesterday (removed too much code from daemon), trying to reduce the code less now.

Ok, so here's the most minimalistic version I can create:

daemon.g

while global.daemonActive == true
	set global.deactivateToolAfterFilamentChange = false

	while iterations < #global.displayChar0
		var lineIndex = iterations ;cache iterations value here since we have a 2D array and need this line counter later again
		while iterations < #(global.displayChar0[var.lineIndex])
			M150 R{global.RGBWhite[0]} U{global.RGBWhite[1]} B{global.RGBWhite[2]} P{global.displayChar0[var.lineIndex][iterations] > 0 ? global.displayDefaultBrightness : 0} S1 F1
		
	M150 R0 U0 B0 P0 S1 F0 ;announce last LED with a dummy
	
	G4 P500

Most notably, if I remove the set global.deactivateToolAfterFilamentChange = false line, things work fine... However, that piece of code has been running for months just fine, this issue only started appearing with my use of LEDs and/or custom arrays.

And the globals (these are created inside a macro that is called from config.g)

if !exists(global.displayChar0)
	global displayChar0 = {{0,1,1,1,1,1,1,0},{1,1,1,1,1,1,1,1},{1,1,1,0,0,1,1,1},{1,1,1,0,0,1,1,1},{1,1,1,0,0,1,1,1},{1,1,1,0,0,1,1,1},{1,1,1,1,1,1,1,1},{0,1,1,1,1,1,1,0}}
	global displayChar1 = {{0,0,1,1,1,0,0,0},{0,0,1,1,1,1,0,0},{0,0,1,1,1,1,1,0},{0,0,1,1,1,0,0,0},{0,0,1,1,1,0,0,0},{0,0,1,1,1,0,0,0},{0,0,1,1,1,0,0,0},{0,0,1,1,1,0,0,0}}	
	global displayChar2 = {{0,1,1,1,1,1,1,0},{1,1,1,1,1,1,1,1},{1,1,1,0,0,1,1,1},{0,1,1,1,0,0,0,0},{0,0,0,1,1,1,0,0},{0,0,0,0,0,1,1,1},{1,1,1,1,1,1,1,1},{1,1,1,1,1,1,1,1}}
	global displayChar3 = {{0,1,1,1,1,1,1,1},{1,1,1,1,1,1,1,1},{1,1,1,0,0,0,0,0},{0,1,1,1,1,1,1,1},{0,1,1,1,1,1,1,1},{1,1,1,0,0,0,0,0},{1,1,1,1,1,1,1,1},{0,1,1,1,1,1,1,1}}
	
	global RGBRed = {255,0,0}
	global RGBGreen = {0,255,0}
	global RGBBlue = {0,0,255}
	global RGBWhite = {255,255,255}

All of the above code has been copied together from various macros, it's usually a lot more generic and this is just the smallest version of the overall stuff that I can produce.

Here's another M122 from that minimal code:

@dc42
Hm, i think I might have created a macro that causes this all on its own without daemon.g ( I just call this macro as is without any params for this test)

var brightness = global.displayDefaultBrightness
if exists(param.B)
	set var.brightness = param.B

var activeLEDs = 0
if exists(param.S)
	set var.activeLEDs = floor(param.S * global.displayLEDCount)
	
var displayContent = "progress" ^ var.activeLEDs
if global.lastDisplayContent != var.displayContent
	set global.lastDisplayContent = var.displayContent
	while iterations < global.displayLEDCount
		;M150 R{param.C[0]} U{param.C[1]} B{param.C[2]} P{iterations < var.activeLEDs ? var.brightness : 0} S1 F1 ;3.5+
		var isFrame = iterations < 8 || iterations > 55
		var isProgress = false ;todo
		var isActive = var.isFrame || var.isProgress
		M150 R255 U0 B0 P{var.isActive ? var.brightness : 0} S1 F1

	M150 R0 U0 B0 P0 S1 F0 ;announce last LED with a dummy

This immediately makes the board crash every time, here's an M122 for this:

@dc42
It looks like this line is the culprit: var isActive = var.isFrame || var.isProgress, when I remove it (and directly use that expression below), it works fine...

Disregard, now that line works fine, so probably some random component to it again...

[Diamondback]

@dc42 Now I prevented it from crashing by moving a global set to a later place...

if global.lastDisplayContent != var.displayContent
	set global.lastDisplayContent = var.displayContent
	while iterations < global.displayLEDCount
		;M150 R{param.C[0]} U{param.C[1]} B{param.C[2]} P{iterations < var.activeLEDs ? var.brightness : 0} S1 F1 ;3.5+
		var isFrame = iterations < 8 || iterations > 55
		var isProgress = false ;todo
		var isActive = var.isFrame || var.isProgress
		M150 R255 U0 B0 P{var.isActive ? var.brightness : 0} S1 F1
 
	M150 R0 U0 B0 P0 S1 F0 ;announce last LED with a dummy

becomes:

if global.lastDisplayContent != var.displayContent
	while iterations < global.displayLEDCount
		;M150 R{param.C[0]} U{param.C[1]} B{param.C[2]} P{iterations < var.activeLEDs ? var.brightness : 0} S1 F1 ;3.5+
		var isFrame = iterations < 8 || iterations > 55
		var isProgress = false ;todo
		var isActive = var.isFrame || var.isProgress
		M150 R255 U0 B0 P{var.isActive ? var.brightness : 0} S1 F1
 
	M150 R0 U0 B0 P0 S1 F0 ;announce last LED with a dummy
        set global.lastDisplayContent = var.displayContent

Note how line #2 moved. This somewhat aligns with the crash in daemon.g where a global set also had critical impact on it...

[dc42]

@Diamondback what values do you set for the global variables before running this macro? I tried the following values, but it doesn't crash.

global displayLEDCount=20
global lastDisplayContent="none"
global displayDefaultBrightness=10

[Diamondback]

@dc42

global displayLEDCount = 64
global displayDefaultBrightness = 10
global lastDisplayContent = ""

The more I play around with it, the more I think it's a timing issue... Sometimes I can do things fine by updating the 64 dotstar pixels with 500ms delay between them but not with 100ms etc.

[dc42]

@Diamondback said in 3.5b1 Reset reason: StuckInSpinLoop?:

global displayLEDCount = 64
global displayDefaultBrightness = 10
global lastDisplayContent = ""

It still doesn't crash for me. Perhaps it depends on what global variables you have created already? Can you share your whole config.g file and any macros that it calls?

@Diamondback thanks.

I still couldn't make it crash with your files, but I eventually got a crash with a similar M122 report to yours after running this macro several times:

var activeLEDs=10
while iterations < 1000
	var displayContent = "progress" ^ var.activeLEDs
	set global.lastDisplayContent = var.displayContent
echo "Done"

[Diamondback]

@dc42 Yea it seems quite random what exactly triggers it, the only things in common for me seem to be some of interaction with custom variables/arrays and possibly the dotstar LEDs, ofc, either one could be a coincidence...

[dc42]

@Diamondback I suspect it's an interaction between DWC polling the object model (which involves reading some values from the heap) and garbage collection of the heap taking place because string or array variables are being reassigned.

[Diamondback]

@dc42 I played around with the DWC polling time this morning but didn't get any immediate results, I'll play around with it some more and see if I can maybe make it go away by setting it much higher?

[dc42]

@Diamondback my next step will be to disconnect DWC completely and then see if I can provoke the reset by sending the command to run the macro over USB.
