ULINK for nRF51822

Julian

I posted this on the Keil website, but got no answers! I would like to use one of my ULINK 2 pods to develop my application. However the Keil interface defines a reset connection. As we all know, the nRF51822 does not have a dedicated reset pin - it shares reset with the SWDIO. Can I use my ULINK 2 by simply ignoring the reset connection and if so - will it be compatible with either the DEV or EVAL boards with either the nordic or Keil toolchains?

    Hi Julian,

    I have not tried to program the devices with that specific debugger, but I've tried the Ulink ME. The problem with unsupported debuggers are these:

    • Flashing the softdevice
    • Erasing the chip using command ERASEALL (re-flash new softdevice for instance).

    Doing application development is not an issue, but there's no good solution to the above bullet points. To answer your question, I believe that the pin assessment is done by selecting NRF51x22 as flash algorithm (however, i've not tested this with that specific debugger).

    Best regards Håkon
