Hello Guys, im new in the forum, but flying with Pixhawk for two years with several platforms both fixed and rotary wing.
Im very used to in the setup, but now i have a hardware problem that i now can be solved with a customized firmware, unluck i dont have program skills.
My gps port is bad, and need to connect the gps to serial 4/5 port. so i need to modify the firmware in order to pixhawk recognize the serial port 4/5 as main.
Some one could help me to do that? mmi firmware using is APM plane 3.1.1
uart b is main gps
uart e is 2nd gps
in the AP_serialmanager line need to be modify UART B for E
