custom board not have 32.768khz crystal

 Have you tried setting the LFCLK source to RC?

Kind regards,

Please add it just below the cmake_minimum_required() line.

Yes, It works,

Thanks Håkon.

I have last question.

DFU is working with

Open bootloader

Secure Bootloader

i have tried without the key it means open bootloader isn't .

Is there any secure bootloader example . and how dual bank concept is working .

for dfu how to config dual bank or single bank concept

[Håkon Alseth]

Hi,

 

If you have specific issues with bootloaders, please create a dedicated case on this matter. My colleagues have better knowledge about bootloaders, especially if you're referring to nRF5 SDK DFU.

 

Kind regards,

Håkon

Hi,

I have enabled DFU in project after that function "Go to definition"

is not working
