Use nrfjprog 🙂

It was an IC issue after that, using the nrfjprog i was able to reprogram the device.

jlink -device nRF51822_XXAA -if SWD -speed auto

works for me with version 5.12g

@jorgemunozags : Have you been able to solve this issue?

Try using the GUI version not the command line and make sure you select the correct template

Try using the older version of JLink (5.02g) it seems to work

Strangely, I can't connect if I manually type commands but if I make a script file just containing

loadbin r q

and start jlink like this

jlink -device nRF51822_XXAA -CommanderScript cmdfile.jlink

it works fine I have windows bat file that creates the bat file, so I can do drag and drop upload of files, I also use the Arduino IDE sometimes to program the nRF51822 and it uploads via a bat file as well

I tried this but the reply back is still the same:

I think JFlash gives this error if the device is read protected.

Try connecting then issuing these commands

w4 4001e504 2
w4 4001e50c 1
w4 4001e514 1

It should remove read protection and also erase the device (though you many want to erase again just to be sure after issuing those commands

Have you tried using nrfjprog to erase the device?

Using JFlasher Portable with tektronix PS. Using JFlash 5.12, also already tried with JFlash Lite. I have been able to program like 5 different types of ARMs using the same programmer so i don't think is related with the programmer itself.

The same issue has already been reported on this post. Do you use a custom hardware ? Which programmer and which version of the Segger tools do you use ?
