can i use j-link debug probes to program and debug evaluation kit?

recently i bought J-Link debugger from the segger, i tried to find the pinout of the SWD of the eval board and connected and tried to program, its not working properly, is it possible to work like this or we have to design our own board for programming and designing purposes, if it is possible to use the evaluation kit or development kit for external programming from the j-link debugger probes? how to achieve it?

hope i can get some info regarding this one!

regards, rangineni balu

    If you absolutely want to do this, I'd recommend you to take a close look on the schematics for the correct version of your Evaluation Kit. You'd most likely have to make sure that the on-board Segger chip is disconnected from the nRF51822, and then connect the SWDIO, SWDCLK, GND and VCC lines from the nRF51822 to your external J-Link.

    Depending on the version of your kit, the SWD lines will either be available on the header P8 (version 1.0), or will only be accessible by soldering (version 2.0). Take a look at the hardware files for your version from here for details.
