Mike,
You should now have access rights to upload a file to one of my Dropbox folders - a link has been emailed to you from Dropbox. You can use that until the issue with openrcforums has been resolved, if you wish - it might be easier and more reliable than email attachments.
regards,
ozphoenix

OK, that's useful. It has pinpointed a loop that doesn't have a timeout, which is why the watchdog occurs. Now to work out why the loop is not terminating. It is related to painting the background of the status line at the bottom of the screen, suggesting something has gone wrong with accessing the display. The processor has special hardware that fills an area of the display, and should generate an interrupt when it has finished, but this isn't happening.
It seems something to do with clearing the display, ready for updating with the new image, is going wrong.
I'll work through possibilities tomorrow.

Of course, or more :) There are more moderators on the forums, and we should report problems when we see them.
Last night the forum was offline due to maintenance, as far as I understood. Perhaps that's the reason we can't upload files at the moment..

Rob has fixed the problem with posting test versions, so I've now posted a new one.
This has timeouts in two places where it was waiting for the hardware to finish filling an area of the screen. If I now get a timeout on those it resets the hardware, adds one to an error count, and now continues execution.
The error count is the single number on the 5th line of the debug menu.
This may not stop the problem from happening, but may recover from it.
I have a 32Gb SD card on order.

Hi Mike,
Good to be able to work with the normal mechanisms again :)

Got the new version - also still get the restart/blank screen when scrolling (not sure if that was meant to happen):

Some more timeouts on the display hardware added, new test version posted. It seems something is causing this hadrware to fail to complete. Let's see if adding these timeouts gets it working, then I can look to find what is happening.

New test version posted. The error count on the 5th line (you say yes zero) wasn't being preserved through the watchdog restart. I was talking this problem through with my wife and realised this.
There is now a second number on the line that is the preserved value.

Hi Mike,
Ok, thanks - understood.
This time, the screen went to a bright orange colour (not grey) during the first time I got a restart(!), but then grey on the retry (not sure if this is relevant, but point it out, anyway)
BOOT REASON WATCHDOG
01E2 020B 01EF
8103 0002 0204

0000 0000 0000 0000 0000 0000 0000 0102

All details and reports verified with a second time.

Maybe not what you were hoping for, but even that might be forward progress :)

As I still can't work out what is happening, I've added a "execution trace", test version posted. Various parts of the code store the fact they have executed, so it gives me the sequence of execution. I'm storing the last 4000 entries, and writing them to the SD card when a watchdog reboot occurs. They are stored in a file called "pos.txt" in the root of the card.
Please try this test version and post the pos.txt file (zipped) for me to inspect. This should either give me a good idea where to look, or where to add more reporting.

No prob - see attached - 3 tries, in one zip file.
pos1 and pos2 were 'normal' crashes (flash to black, show grey screen, restart)
pos3 went to 'snow lines'-corrupted display first, then continued to 'normal' crash/restart after about 1-2 seconds

All stopping in the same place, just about to update the status line.
How "grey" is the grey screen, is it the same "grey" as the status line background?

No -- both my wife's eyes and mine believe that the 'grey' of the 'flash once' screen is more 'blue' (like my selected background colour -- red:0, Green:15, Blue: 30) than the steady grey of the status line - if you can guess what we mean. BTW - and, only as a reminder - sometimes the screen that 'flashes' during the 3-4 seconds of the restart is orange, not blue/grey - not sure if that's relevant.

I found a bug where I only waited for the background to clear every other "pass". If the menu operation took too long (lots of SD card reads!), then I could try to use the hardware before it finished. This may be the problem. Normally the background clearing finishes anyway, and the code doesn't need to wait, but when scrolling a long list of files, I can see a wait being needed, and this could be missed. It seems my radio/SD card is just fast enough not to fall over this.

New test version posted with the fix in.

Hi Mike!

That sounds hopeful - if that is the case, I'm glad you could find it before a lot of X12S move on to Ersky9x.

I'm away from my house for about an hour - I'll try the new version as soon as I return and report. Does the new version have any remaining debug code in it that will report anything - do you need a 'dump' returned to you, whether or not I get a failure?

Regards,
Peter M.

Yes, all the debug code is still in. You only get a dump (pos.txt) if you get a failure, although you may cause a watchdog reboot by pressing the T6 switch down, which is how I was checking the dump works.
I only really need a dump if you get a failure.

BINGO!

I do believe you have solved it :)

Unable to cause a restart, though scrolled for about two minutes - the longest time prior seemed to be about 30 seconds or less.

And, so far, no occurrence of screen 'snow lines' - not sure if it was related, but that one only appeared infrequently and not on every restart - will hopefully not see that appear again, either. I will, obviously, report back if either issue shows it's head again, but hopefully not.

Congratulations, Mike - thanks for the persistence and effort.

I'll leave it for you to decide when to post a version with the debug code taken out - I have still a number of things I want to do with the X12S before I formally 'use' it, so no hurry yet.

Also, I'd like to discuss moving to the next steps in the UI, if I may, when you're ready to take input on this one. I know that this restart issue has been bogging you down a bit, so let me know when you are recovered enough for separate matters.

I have no idea why I had code in that only waited for the background to clear every other pass, look like it was something to do with timing how long the clear took.
I'll post a version without the debug tomorrow. Most of it is already removed as it was conditionally compiled so just needed turning off.
Please do make suggestions for the UI, I can look into them.

Hi Mike,
Ok, thanks - will get it and install it and move on :)
Have had to be continually charging mine during the recent testing - so much so that I ordered the LiPo upgrade kit, but it will not even ship from China until sometime after March 30th, I believe :(
Once again, thanks for your sterling efforts in resolving this most recent problem - it sure was a doozy!
Will come back to you in the coming days with UI discussion points - looking into it further now.
