 Bigger Bigger  Smaller Smaller  Reset Reset

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...

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

Replacement for the Arduino IDE: UECIDE - Proper serial terminal, graphing facilities, plugins, overhauled internals.
Java isn't bad in itself, but it has enabled morons to write programs.

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

Examples can be found in your IDE.
