How to debug a power off issue with multilink?

[huangda1982]

Processor: MK64FN1M0

Debuger: multilink universal fx

Problem: When power off --> on my device, a range of flash ROM corrupted, access these address will cause a hard exception. Then attach to the processor whit multilink and see memory, that range of flash keep changing (while refresh button click).

I think it caused by what happened at the moment power went off. How do I debug this?

Thank you.

Hi,

When power off, the flash is also shut down. It is impossible to debug at that mode.
