Howdy!
I have an early-unit DM42 I'm seeing some odd behavior with.
If I leave it on my desk overnight, when I turn it on the next morning it's at the boot loader screen; pressing EXIT causes it to verify the QSPI flash, and then launches Free42, although it's wiped memory ("MEMORY LOST").
Has anyone else seen this?
I've tried charging it overnight, but I don't think it's a battery issue; the charge indicator shows a full charge.

Re: DM42 spontaneously rebooting to boot loader
The DM42 does not have a rechargeable battery. I operates on a 2032 lithium coin cell. Have you tried changing the battery for a fresh one?

I may have a problem!

Re: DM42 spontaneously rebooting to boot loader
Oh, good point! I'd totally forgotten that, because it just lasts _forever_. I think I was confusing it with the Prime, my other go-to.
I'll throw some new batteries in it tomorrow and see how it does. That may be it, but if that's the case I've got some distrust over the battery gauge, because it's not reporting a low battery.
Thanks!!
I'll report back here with results for anyone else that's curious.

Thirty-six hours and it's still running!
Interestingly, the battery gauge was only one bar down from full. I think I should be trusting the voltmeter or just looking for this behavior in the future.
Thanks again for pointing me straight on the no-rechargable-battery thing! I feel pretty stupid!
