Problems to use and program a nRF52832 custom board.

[nemunoz]

hi to everyone!

I am using nRF52832DK with Keil5 and nRFgo Studio to program SoftDevice.

Now I want to program my first custom board, but it looks like I can't connect to it.

When I use the nRFgo Studio I get the next error in bold: "No device detected, or readback protection may be set"

And If I press the Recover button, to remove the readback protection, I get an unknown error.

If I use Keil5, when I press Flash->Download I get: "No Cortex-M SW Device Found" and "Error: Flash Download failed - Target DLL has been cancelled".

And the output terminal:

Is there a way to debug the communication between these programs and the custom board or a way to find where could be the problem?

Thanks in advance!

In this case I have this custom board connected through P19, but I also have another connected to P20.

In the P20, I just tried what you told me and I have half success. A lot of time (about 80%) the connection fails but, at least, I finally can connect to one of them. I think the problem are the wires and I had to braid them very well to have this little success.

And yes, I am programming from a nRF52832DK board.
