Found a trouble with read back protect

[jasonbu]

using nrfjprog --rbp all and got a success

and using nrfjprog --readuicr got unavaible

but if using j-flash and read whole chip, it's able to be readback...

it only happens in

N52832

QFAAB0

1636CQ

tried 5 chips and all got this trouble... quite confuzed

I recommend you look up the register map for the read protection and write directly to that address, JLink commander can definitely do that.

BTW. There is another current thread where someone accidently locked their nRF52 by writing data to it in the wrong format.

I have locked an nRF51 by writing zero's to the memory mapped hardware registers, so I imagine the nRF52 is the same and writing zero to one memory address will set the read protection.

If you see this thread,

devzone.nordicsemi.com/.../

it tells you have to lock by writing to memory.

I would do that to confirm its not an issue with nrfgo
