I was going to suggest the same as Jan. It sounds like a connector is probably right on the brink of unplugging so the connection is intermittent.

First real issue I havenāt been able to solve or figure out. Iāve reflashed firmware, tried rebooting, reverting to prior firmware doesnāt work, ectā¦ Havenāt used my board in a few days and it was working perfectly before. But now it just gets stuck at this screen. Any idea what I should try?

Yeah, this has unfortunately been reported a few times. I donāt know why it happens. Must be a micropython bug.
The solution is to use the davega tool and make a full backup. Then erase flash, reinstall the bootloader and restore the backup. I hope that helps. Sorry about this. Hopefully it doesnāt happen too often.

No problem at all dude. Thatās exactly what my next move was going to be. Iāve been trying to use the windows tool and canāt seem to get anything to flash correctly. Well, bootloader flashes fine, but the firmware and backup feature doesnāt and I get this.

And after my literal 42nd attempt switching back and forth from my Linux machine running virtual box with windows and my windows machine I got it to work somehow. Did nothing different haha.

Yeah, export/import is extremely flaky on Windows. I yet have to look into that. I should be able to compile a linux version so that you donāt have to use the virtual box. That should also remove the flakiness. It only happens on Windows. On a Mac, itās working like a charm.
Iām glad you got it working at last!

Perfect. That would be awesome. I havenāt run windows in over a decade. The Linux tool you did have always worked great.

Will do when I get back home in just a bit. Thanks dude.
Got this yesterday while riding, DAVEga X is running through uSplit. Constantly repeating.
That looks as a bad contact on the MOSI pin of the display. DAVEGA thinks the display has restarted and it re-initializes it. This is fixable in software. I can add a preference for disabling the display re-initialization. Will try to do it later on today and will send you the update to test out.
You are still able to access the menu, right?

Yeah it worked fine again after a restart, no hurries.
Oh, so it was just a one-off? I thought you were getting it all the time. If it just happened once, probably the display somehow got into a weird state and didnāt communicate back over SPI as expected. Please let me know if it happens again.

Yeah it happened just once. I will report back if it does it again.
