J-link v8 works with NRF51822 ?

Hello everyone,

Do you know if the J-link v8 is valid for programming and debugging the NRF51822 ?

Thank you

  • Hi,

    If you read the comments:

    Pros: Well, it does work, IF you use the older DLL and don't need SWD messages (but everyone needs these!)

    Cons: These are clones, and Segger's firmware blacklists the serial number in the hardware. So you can't install the firmware after 4.42a. If you have the DLL after 4.42a installed, then the IDE won't be able to talk to it. I couldn't get the Serial Wire Debug- which is responsible for the ITM printf/getc in code to interface with your IDE window. That's unfortunate as that's a really useful feature.

    This, and due to the price it sells for indicate that it is a Segger clone. We do not encourage purchasing clones/counterfeit equipment.

    I would recommend that you look into getting a nRF51-DK instead, these have an on-board debugger with "DEBUG OUT" connector. This will guarantee that you get a Segger certified debugger.

    Cheers, Håkon
