" JLinkARM DLL reported an error" On NRF52832, J-Link V9 Programmer

[HoweXu]

Hello,

Our custom board (nrf52832, S132) seem enter to the read back protection, J-Link could not connect to the target in any ways.

We tried the command "nrfjprog --recover" to fix it. However, the " JLinkARM DLL reported an error" still happened.

Here is my information and error log:

Is your customer the person in this ticket?

https://devzone.nordicsemi.com/f/nordic-q-a/70492/how-to-erase-the-data-in-nrf52832

If not, please try the same suggestion. Let me know if that doesn't work.

Best regards,

Waitting your reply, thank you

[Edvin]

Did you try to add the nrfjprog --recover command to the loop .bat scripts as I suggested. In fact, let me write it for you, so you can run it from your command line. Download and run the attached file:

Fullscreen recover_loop_script.bat Download

:loop 
nrfjprog --recover -f nrf52 
goto loop 

Use the key combination "ctrl + C" to exit the script if it worked.

Important: When the script is running, power cycle the DK a few times until the scripts manages to hook onto the nRF.

Best regards,

Edvin

Hello,

Of course! We tried your suggestion first time, and the .bat continuing in looping almost 60 times! The cmd always showed the same result as "Recovering device. This operation might take 30s.
ERROR: Recover failed. Please make sure that the correct device family is given
ERROR: and try again."

[Edvin]

It shouldn't take 30 seconds when you power off the device. Can you please disconnect all other nRF devices connected to that computer? When no devices are connected, the script should run through several times per second, giving an error:

ERROR: There is no debugger connected to the PC.

The idea is that you then power on the DK, and then maybe the debugger can catch on to it before it locks down. If it doesn't work, it will start the 30 seconds. Don't wait for this to finish, just power it off again immediately, and try again. Basically, leave the  script running, and spam the power switch quickly on and off.

BR,
Edvin

Hello,

A new day! We tried your suggestion: keep no nRF devices connection to the computer, and yes the ERROR "There is no debugger connected to the PC" appeared, and then we connect the locked board and JLink to the computer. The script keeping running, and we powered off and on the board immediately when the "30s" started. However, the probleam still exist.

[HoweXu]

We compared a normal board with the locked board excuting the recover command, here is the log comparison:

It looks like the normal board could access the AP reg after DP reg, however the locked board always hooked by the DP reg accessing.
