RAK 811 tracker need some help please

Hi I have a RAK 811 Tracker board and trying to make it work. I’m using the RAK (somewhat) documented method. I have a Segger Jlink working and can program the board, however I’m stuggling with what exactly and how it has to be updated. I would appreciate if some one could help. Maybe someone has a commented main.h file explaining what needs to be changed a where including what is big and little endian.

Regards
