Hi @ScruffR,

Yes double post but with i think two different question for same issue. Sorry for that :slight_smile:

Our product is about to release and got this issue so we both are searching for solution.

Don’t we have anything like HardFault_Handler in particle simillar to STM32?

Thanks.

The SOS panic handler is exactly such a thing and the scheme I proposed in the other thread would build onto that in on a higher level.

To make use of the scheme outlined in your link above, you should be proficient in using OpenOCD and have a JTAG/SWD debugging hardware (e.g. Particle Programmer Shield).
But since I’m not aware of your individual experience with getting that low into the HW I tried to approach your issue from the higher level down.

This is where/how this is implemented in device OS
