@Paul - Would you be able to take a close up picture of the backside solder points of the serial debug connector (3 pin next to USB C)?
My AI was overheating too until it stopped booting all together. I was looking to monitor serial as I applied power and that is when I noticed what appeared to be an unclean solder point...its not shorted there is a 99kOhm resistance between the two points. https://drive.google.com/file/d/19pRcHcP9APTcQ6nWiU708ca8ID9PtNXH/view?usp=sharing Mike On Wednesday, September 25, 2019 at 7:51:41 PM UTC-4, Paul Richards wrote: > > I got 2 BeagleBone AI's from Mouser and started working with them today. > > Both of my boards boot and run with the 08-03 build. > > I haven't done anything to modify the contents of the filesystem, I merely > booted and connected via Cloud9. > > On both boards, the main CPU heat sink and the Kingston RAM module > immediately > heat up and run incredibly hot.
