unintended flash erase

gorazd

Hi,

we have a nrf51 mounted inside an AC motor housing which we assume is causing an unintended flash erase from time to time (checked with nrfjprog --readcode).

Is this a valid assumption? Are there any solutions for this problem? E.g. shielding the flash chip etc.

    Really looks nicely erased... to do such mass erase it would probably need to write into UICR and then reset the chip. Not sure how probable this is in case you have the chip in strong magnetic field. But it would be more probable that some corruptions happen already before so it would be interesting to dump the chip while it is still working and compare against the original HEX image.
