Hi,

I am also using a MBN52832DK, and I am unable to get started on developing on it using the nRF5 SDK. After reading the docs, I think I should create my own custom_board.h file, but I am not sure how to do that. I am a beginner, can you help me out here. Thanks in advance.

Hi,

We are using the J-Link base from Segger.

In a closer look we detected that a different LDO voltage regulator from the original specification was soldiered on the board. So we are waiting for the correct LDO to replace it and continue with the tests.

I'll update this ticket as soon as we have more info.

Thanks,

Hi,

[quote user="neves"]Meanwhile I notice that the target voltage on our board is 2.7V in contrast to DK board that is 3.30V. Can this have any influence?[/quote]

This depends on your programmer used. If you use a programmer that has a "set voltage" (like the nRF5x-DK or the J-Link Lite), normally 3.3V, then it is expected that you might lose the debugger connection, especially if the supply voltage gets a dip. In this case, I recommend powering your board with the exact same voltage as the programmer expects.

What debugger are you using?

Best regards,

Håkon

Yes we have the 32kHz crystal on board. However we did try with the RC with same result!

Does the module have a 32 kHz crystal and your board not? Of so, you must use the RC oscillator instead.
