Hi All...

I have a device with an ARM Cortex M3 processor sealed in plastic, and its firmware is stuck in an infinite loop. There is no way to reset it without breaking it open, which will destroy it. Any ideas on how to stop it so when it comes back on it can restart? Maybe freeze spray? The battery will eventually run dead, but tis going to be a while...

Just thinking of the obvious - remove the power (Battery..)..?

Place in freezer for 24 hours then rewarm to room temperature.  May work, may not.

Put a cellphone right next to it and dial somebody.
No, I don't answer questions sent in private messages (but I do accept thank-you notes...)

Only if the seal is not metal. Faraday cage :)

Cycle power. Give it couple seconds between off and on.
