I wanted to give the PX4 flight stack a try, and tried to flash it using QGroundControl, but I couldn't get this to work, whatever I tried.
I do have a pixracer, and within the ArduPilot environment everything just works. That is, for instance, flashing it with an ArduPilot firmware using MissionPlanner works with no issues (ane everything else also works).
I'm on Win7 btw.
I do have QGC installed since a while, but believe to have the latest, it says v3.2.2 in the title.
QGC nicely connects to the pixracer, with ArduPilot flashed, i.e. I do see the parameters, the HUD is working, and all that. So, this looks all OK to me.
When I'm going to the Firmware tab, and either do as advised and unplug the usb, or go there with the usb having been unpluged before calling QGC, and then plug in the usb, as told in the tab, just exactly nothing happens ... absolutely no change or anything in the display, for however long I wait. The pixracer in the meantime boots and gives the buzzer and led signals I'm used to get when it boots.
It probably is just a tiny silliness of mine I'm overlooking, but I have no idea what it could be. Any suggestion/help would be much appreciated. Wrong bootloader? Dirver? No idea.
THX, and cheers, Olli
