Okay, I'll recheck my design and update accordingly.

Thanks!!

Hi,

It is recommended to have cable length of less than 10 cm for reliable connection.

How long were the wires which caused an issue?

The Long lines from the voltage source were the Problem. After adding decoupling capacitors near the VDD and GND pins of the programming adapter, my Segger J-Link was able to program the chip. Shows again, how importent proper supply stabilisation is. Thanks

Just to be clear, it should not be necessary with any capacitors or resistors on the SWD lines. But you will of course need all the decoupling capacitors, etc. to make the nRF52 run.

I could program a N52832 (BlueNor BC832) over the SWDIO and SWCLK lines, without any capacitors, using the JLink OB from the PCA10040. Are you sure your bare nRF52832 is powered up (at 3.3V) when you try to program it?

Yes, it needs at least some capacitors.
