nrf52832 sparkfun breakout board program with SDK14.0.2

[anomp]

Hello everyone! I am trying to program a nrf52832 sparkfun board through a nRF52DK. I have already gone through the pin connection guide succesfully and I can flash succesfully hex files which however do not seem to work a least with SDK14.0.2. As I have read here and here sparkfun's board comes with pre-programmed bootloader(compatible however with SDK 11) in order to be compatible with arduino IDE? So what procedure should I follow if I want to run code for SDK14.0.2? Should I define a custom_board header only and if yes where should i put this definition? Or for my examples I must create a new directory structure for the new board like those already existing for PCA10040? Do I need to build and flash a new bootloader for current SDK? If yes,can you please provide a guide for that? As you can understand I have turned a bit confused! Any help is appreciated! Thank you in advance!

Hi,

Which examples have you tried? Are no examples working, or only BLE examples? If you tested BLE examples, did you remember to flash the softdevice? If you have erased the entire chip using nrfjprog or nRFgo Studio, the bootloader should be gone. There is no need for a bootloader when using SDK 14, unless you want to do device firmware updates (DFU), etc.

Please have a look at this guide on using the SDK with custom boards.

Hi anomp;

You do not have to do anything. I use the same board with SEGGER ide. Working without problem.
