I used bf533-ezkit as a pattern.
I made /include/configs/bf532-ahrs.h file, /board/bf532-ahrs directory (copied bf533-ezkit and changed) and placed my board to the list in boards.cfg file. Command make bf532-ahrs_config said Configurin for bf532-ahrs board..., it's ok . But make all finished with cc1: error: missing argument to "-mcpu". I think that i did some simple stupid mistake but i ca't find it. I'm the "unfortunate soul stuck in Windows environment" and i'm not familiar with Linux. Can anybody help, please?
