Hello Kenneth,

Thanks for the information. It looks like I got a very old version of the chip.

Best regards, Marcin

The chip you are using is the 1st hardware revision of the nRF51422, it's not recommened for new development and the pre-programmed firmware was never intended to be re-programmed. It's not possible to write new softdevice to this chip, please refer to nRF51 Series Compatibility Matrix document for details.

Also, do not --chiperase when programmed. After the --recover the device is also erased.

Which version of nrfjprog are you using (nrfjprog -v) ?
Can you run again the command with the extra option --log (or --logeverything if --log gives error) and post the generated log here? Thanks.

Hello Aryan,

Thanks for the answer, but it seems that those splitting is not correct:

nrfjprog --chiperase -f NRF51
ERROR: One or several arguments are missing. Use --help to read about the valid
ERROR: argument combinations.

I tried also:

nrfjprog --eraseall -f NRF51
Erasing addresses 0xA000 to 0x3FFFF.
Erasing UICR flash area.
Applying system reset.
nrfjprog --program test.hex --verify -f NRF51
Parsing hex file.
Reading flash area to program to guarantee it is erased.
ERROR: The area to write is not erased.

Doesn't work. Any more sugestions?

Regards, Marcin

split your last command

nrfjprog --program %MERGE_NAME%  --verify --chiperase -f NRF51

into

nrfjprog --chiperase -f NRF51
nrfjprog --program %MERGE_NAME% --verify -f NRF51

Then --chiperase will ensure to remove the readback protection before --program takes over

The draw back of mixing many commands into one is that IT DOES NOT NECESSARILY EXECUTE IN THE SAME ORDER. If you want to ensure the order of the commands, then do not mix them.
