Disabling readback protection (nRF9160)

[konr]

I'm trying to program nrf9160 but getting an error due to readback protection.

I have tried the following commands:

nrfjprog --recover

nrfjprog --recover -f NRF91

nrfjprog --recover -f NRF91 --log (no log messages)

I also created a .bat file which includes the following script,

:loop
nrfjprog --recover -f nrf52
goto loop

that didn't work either.

Any other idea on how to fix this issue?

Thanks in advance.

Hi.

Are you using the development kit or a custom board?

Could you provide the log from nrjfprog by adding the --log argument?:

nrfjprog --recover -f nrf91 --log
