Hi I probably have done multiple or bad inicialization of flash memory in code and my MiniBeacon (www.alibaba.com/.../Nordic-bluetooth-nRF51822-logo-customizable-minibeacon_60408141084.html) doesn't work now. It was debugging by nRF51 DK. I see debugger nRF51 DK in nRF Studio and in Keil, but chip of custom board doesn't see anyone.
- Can bad inicialization of flash damage chip ?
- Can I recover it somehow ?
UPDATE 30.3.2017: I figured out somehow, but this issue occurs again. Log: *
