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 the end, it was a wiring problem, more or less. In fact the problem was the nRF52832 chip wasn't welded very well.

A new custom board, with the chip welded again and re-checked, is fully working.

Now I have problems to get the output terminal through SWD, but I'm going to ask it in a new question.

Thanks for your help, Stian and Angus!

Ok, I'm glad it worked out!
