UNO Q - Current sources - running a sketch, then running APP, power off and on - Faults

[KurtE]

Today I synced up to the latest sources and built both on PC and on Q.

I burned bootloader on Q with latest. I ran my Weather 2 app.
Up on github in: https://github.com/KurtE/Arduino_UNO_Q

Stopped the APP.

I then went to PC and uploaded a sketch, in this case test of Events, which I uploaded IDE2 with todays build.

Went back to APP Lab reran Weather2.

Turned off power to Q, turned back on and it faults: (data on Serial D0, D1)

Kurt I am seeing the same thing as you.

UPDATE: Still seeing it periodically:

Also Bridge apps are having issues
