Hi all,

I hope this is the right place to ask...

Since flashing a new build yesterday, my OVMS doesn't boot normally
anymore. What I see in the USB console are 5 early crashes (reason 12
for both CPUs), then the module falls back to running without auto init.

What I have tried: switching to previously working ota, flashing &
booting factory images 3.2.15 and 3.2.14 from dexter. Removed SD card
since reason 12 may point to a vfs problem.

What else can I try? In my understanding it doesn't make sense to do a
full reflash incl. boot loader, since booting as such works... or am I

Is any other information necessary to tell what's wrong?

Thank you!
