Bug report

Issue details

Hi all , I programmed the drone with firmware 4.5.0-beta2 using these definitions , to remove the items I don't need/interest .
custum_hwdef_build.txt

Loading the firmware , the drone seems to work without problems , but it returns every 2/3 seconds this message :

Loading clean firwmare 4.5.0-beta2 , this problem does not occur . It could be caused by my definitions but without a definition of the error I wouldn't really know where to look . Thanks
