Flash Nordic sample using Segger or PlatformIO via SWD into puckjs

Hello,
I am trying to flash blinky sample from Nordic SDK into my puckjs v2 via SWD.
I have tried both Segger and PlatformIO. The download seems to be successful but when I run it in debug it stops executing in reset.S line: bl z_platform_init.

Do I need to modify the sample code in any way to run it in puckjs?

Thanks
Adam

Hi Adam,

The Puck just has a completely standard nRF52832 chip in it, so the samples should work.

However are you completely erasing the device first and also flashing a matching softdevice? Because if you're not using a matching SDK (Puck uses SDK12) then you'll hit problems

Hi Gordon,
I added MCUBoot and it does stop at a breakpoint in main.c now.

Thanks
Adam
