T-Watch-v2 continously rebooting after uploading new version

[Jan-NiklasB]

Hey there,
I uploaded the actual version (cloned on 2021-12-11, Stamp: f1a3344) on my factory new T-Watch V2.
After flashing the watch continously reboots.

I had to pull lvgl 7.11 instead of 7.8 bvecaouse the 7.8 isn't available.

Some help would be appreciated.

Having the same issue here on TWatch 2020 v1: "... gui" -> screen dims -> hedgehog.
This watch has been successfully running an older version (from march?) before being updated.

[MoorPoor]

hei
Are you uploading with platformIO / visual studio or with arduino IDE?

[pruttelherrie]

I'm using VSCode + PIO on Linux.

[MoorPoor]

same setup here.
strange... You added the lvgl lib like mentioned here?

if that is not helping for now, try watchface-ng or another older brench. they should work

[pruttelherrie]

No, I had lvgl/lvgl@^7.7.2 in Platformio.ini, which pulled lvgl 7.11

I tried to add the lvgl lib like mentioned in the other issue, still rebooting.
Serial terminal shows:

Rebooting...

[Jan-NiklasB]

Sorry, for some reason I wasn't notified about the new posts....

@MoorPoor I for my part used PlatformIO as suggested (tested under Win7 & Linux Mint)

[pruttelherrie]

Ok, while trying to re-build (which takes some time on my laptop ;) I connected the watch again and after a couple of reboots it started to act normal?!?
For now it seems to work ok. (please note that I did copy the lvgl lib to .pio/libdeps/t-watch2020-v1)

Weird.

[Jan-NiklasB]

I didn't copied the lvgl but pulled it by PaltformIO...
The watch kept restarting for 10 mins or so.... so in consequence I disconnected the battery.... Also the version flashed by factory was unstable and rebooted after a short while, which was the reason for me to flash the newest version....
