Hello everyone!
I've been having problems in loading firmware to pixhawk. I've used apm planner 2.0 as instructed. Pixhawk is connected to the computer via usb connector with peripherals connected to pixhawk which includes GPS with magnetometer, switch, buzzer and telemetry.Everytime I start loading firmware, it instructs me to unplug the pixhawk and plug it again afterwards. Status message will then be "downloading" then, "attempting to find com port" and stops. I checked again the pixhawk port in the device manager and still it is present.
Can somebody tell me what to do please? or is the lacking of peripherals affect it as well? I hope somebody could help and could give a comment. Your comments will be very much appreciated and is a great help for me for sure.
Thanks in advance,
Cherry

Hi Cherry,
How's your Pixhawk so far?
Hello Jay,
For now, I'm still having problems in terms of arming. The peripherals connected were GPS, compass, buzzer, and the safety switch. I still can't do the Radio Calibration since I have problems on the connectors/wires. Have you tried arming it without calibrating? I can't, I just want to ask if you've tried it successfully or not, because apm can do arming without Radio Calibration.
Thanks,
Cherry
I think you need to press the safety switch first before arming. have you do this procedure?
Hello Everyone!
Sorry for the late notice. I've already loaded firmware to the pixhawk successfully! Thank you so much for your comments. :)
I've unplugged the peripherals connected except for the safety switch and the buzzer, as what ItCanOnlyBeJared adviced. I've used apm planner 2.0 at first, but still nothing good happened. I've also tried using QGroundControl 2.0.1 beta version for Windows, that is for upgrading the firmware and it works. It stops until 90% yet the status says upgrading was completed. And so, I've opened again apm planner 2.0 and connect pixhawk on it. Luckily it connects but only at once. Connecting it for the second time, third, and so on doesn't work anymore. So, I again tried loading the firmware by using apm planner 2.0, and fortunately it was successful! :D
After a very long wait hooohh! We just really have to be patient. :D I hope this could help. Problem solved! Another problems are on the queue. Let's just enjoy exploring pixhawk and see you guys on the next discussions!
Kind Regards,
Cherry
You should be able to flash your firmware properly with everything unplugged with the exception of the switch in some situations. Leave the buzzer plugged in too. That shouldn't interfere with anything at all.
On my PX4, I tend to unplug everything since I hate the wires flailing everywhere. So I just leave in the buzzer and the safety switch.
I tell you though.... These things are a pain in the arse.
Thank you so much. Your advice really helps! :)
I have successfully loaded the firmware and I'm using WIndows 7. Thanks for the comment. :)
Hi I have the same issue I recently purchased a PX4 but have been unable to upload its firm ware. I have searched the forums and spent hours trying to get it to connect. I am now using APM2 after MP did not seem to work. The drivers (they say they are working properly), changed the SDHC used the battery to power up. I have the musical tones but it wont connect after I unplug and plug in same thing "attempting to find com port"
I am about to try with out the GPS as this may be draining the USB port too much, other posts seem to have fixed this with the use of a powered USB port.
Any advice here too will be appreciated.
Thanks Gaz
Try unplugging the peripherals except for the buzzer and the safety switch. Loading the firmware on pixhawk is really one of the crucial steps but I know you'll get there! :) God bless you!
Thanks for your comment,
Cherry
