nRF52 preview DK

[pltv]

I have an external board based on nRF51822 QFAC. I have a nRF52 preview DK. Will it be possible to detect my external board if connected via the preview DK. I tried and the external board did not show up. Just wondering if anyone has tried this before.

Can you try to program the nRF51 DK with the nRF52 Preview kit? That way we can see if debug out on your kit works or not. I have tried this with a nRF52 Preview Kit and a nRF51 DK using Segger J-Link driver v5.02f and it works.

And does the on-board nRF52 get programmed when you try to program an off-board nRF? In that case it might be that the external voltage is not detected properly.
