I am currently working on custom firmware hosted by the nrf52832 SoC on a custom PCB. The project is built with a makefile and armgcc, using the "nRF5_SDK_15.0.0_a53641a". When building the .hex file of my firmware i receive a an error from the boards.c file in the sdk....."boards is not defined". I would like to know how to fix the error and build my .hex file.
