PCA10040 DebugOut to nrf52832 breakout w/ 4 SWD signals

[yf13]

Hi,

I have a PCA10040 board (nRF52-DK) which has a P20 debug out interface. I've got another nRF52832 breakout board which has VCC/SWIO/SWCLK/GND wires for debug/programming.

My question is how can I use the pins of P20 with that other breakout board so that I can at least program it through the P20 interface? I can connect the SWIO/SWCLK wires easily, but how to wire the other pins?

Regards,

Thanks! will try and report if there are still issues.

Yet another problem I have is regarding the relationship between nrfjprog and JLinkExe. I got an old JLink-OB programmer from friend which seems to support JLinkExe 5.x but not JLinkExe 6.x. How can I use that programmer with nrfjprog tool? I found even if the oldest available nrf command line tools (v9.7) contains JLinkExe 6.2 ... does this mean that there is no way to use that old programmer?

I'm not sure if 5.x had device support for the nRF52, but you can try to use it with JLinkExe instead of nrfjprog. It has the same functionality.

Thank you Vidar Berg for the information on P20 debugger out usage. I tried it and it works.

The other Jlink-OB might be too old thus I won't spend time on it any more since the nRF52DK can do the job.
