i’m facing a problem getting connected to mission planner !
last month i tried PX4 flash then arducopter, it works ! you never know, no it’s not working, installed PX4 again the ardurover, then arducopter, no hope.
Note that i still have another problem once connected, which is :
Orange Cube - Failed to update IO Firmware, fix it and than reboot
no Main PWM outputs !!
this is creating a big delay to me !
pls help.
