JLink cannot connect using nRF82540 DK

stathisv

Hi all,

I have a Raytac MDBT50Q-DB board which I  was programming using an nRF82540-DK. It all used to work fine, but now JLink cannot connect to the Raytac board anymore and Segger Embedded Studio gives me the following error message:

Running the JLink commander (Linux version) produces the following output:

I tried running 'nrfjprog --recover -f nrf52' but that is unsuccessful too.

Is my board bricked? Any help is greatly appreciated.

    I assume you have checked that the device is powered and the connection is ok? Can you test nrfjprog --recover --log (with the log option that is)?

    Thank you for your reply. Yes, the target is powered and and the SWD connections are OK. I run the command 'nrfjprog --recover -f nrf52 --log' twice. Here are the log files, that look somewhat different.

    Did you enable pinreset? Can you try to connect the reset pin to vdd and run the recovery sequence again?

    That did the trick, thank you. I connected P0.18 to Vdd and then J-Link connected to the board. Then I used 'nrfjprog' to erase the UICR, I did not run the full recovery. Now J-Link connects and the board is back working again without having to connect P0.18 to Vdd. Not sure why.

    The board was stuck in reset state. Connecting the reset pin to vdd made sure it could exit the reset state.
