I have "Pixhawk 2.4.7 PX4", when I go to "Mission Planner 1.3.74" then I see there are two option to Install Hardware
1) Install Firmware
-It has all Firmware Named as "Copter..."
When I select "Copter 4.0.5 Official" then It ask for Platform,Version and Firmware.
2) Install Firmware Legacy
- It has all Firmware Named as "ArduCopter..."
I am confused how to proceed to setup my "Pixhawk 2.4.7 PX4".
Please help.
