Hard to say. Let us know if you figure it out or stumble into more issues.

I tried a third chip and it worked. Still cannot figure out what the original problem was other than that the chips were damaged.

Pull-ups shouldn't be necessary. But I just noticed that you are using an old version of nrfjprog. The current version is 9.6.0. Can you try that, and also make sure that you have the latest JLink drivers?

I have checked the connections and changed the chip. Nothing yet. I read somewhere else that the SWDIO pin might need a pull up resistor. Is this the case with nRF52832? If I understand correctly nRF52832 has an internal pull up.

That's precisely why I asked for a photo in the very first place, to check the wire connections visually :)

I get about the same nRFgo Studio messages and JLinkARM DLL errors if I only connect VTG to VDD, but leave the SWD lines unconnected. Is it possible that you have bad connections between the Segger MCU on the DK kit and your prototype? Is it possible to use a Multimeter to check that you have proper contacts between the two devices? Are you absolutely sure that you haven't reversed SWDIO and SWDCLK?

I used Pin 9 to power up the custom board. I have also tried P1 to no avail. I am gonna try and replace the chip with a new one and try to program it from a Jlink Adapter instead of the test board. Will share the results.

Which VDD pin on the PCA10040 you use to power up your target board? The VTG (pin 8) of P20 is only for sensing purpose and cannot be used to power up external boards. How about using the VDD from P1 to power up your target board (you still need to connect VTG pin 8 of P20 to the VDD in your target board for sensing purpose).

No. Its not a production board. It is a prototype and I do connect it manually to P20 on the developement kit. This is the first time I am programming this board.

The board is powered from the PCA10040. Through the VDD pin and GND.

Do you have a breakout kit for your custom board so that you can manually connect it to the PCA10040? When you said "part of a cable input to the board" it almost sounds like you have a production board so does that mean the programming used to work before and now it is not working?

And one dumb question: you custom board is powered up separately, correct?

You cannot see where the wires are connected in the custom board because it is a part of a cable input to the board. But I rechecked a few times that they are connected to the correct pins.

I get the message No device detected or readback protection may be set when I start the nRFgo studio with the custom board connected. When I choose recover I ger Jlink ARM dll reported an error.

When opened without the board connected, it displays the DK.

Wait... with nRFgo Studio if the remote target is not found it should display your DK (eg. PCA10040) info instead. And that "JLink ARM dll not found..." message seems to indicate something wrong with your pc and not the target h/w?

What do you mean by "not make sense because of the housing"???

Posting a picture will not make sense because of the housing. But the conection is made like in this Question.

I tried nRFGoStudio too. It also says JLink ARM dll not found or no device found.

Can you take a picture of the connections between these boards and show it here? Have you tried the nRFgo Studio for programming and check the error messages there?
