Maslow Firmware not uploading -using arduinoIDE- Need help fast!

Troubleshooting

What does your Device Manager show under COM & LPT?

Run devmgmt.msc

Edit: If you see the COM port associated with the Arduino, you can right click and uninstall with the check box to uninstall the driver.

There are some helpful tips here too:

so i’ve tried looking and running devmgmt.msc but I am not an administrator on the computers I’m using. Please tell me if you have found any other solutions!

Hi,
It is official! Maslow is on the other side of the pond! I’ve got my kit and I think that my Maslow is first installation in Poland!
But I immediately run into problems ;-((

  1. I have old lenovo with WinXP.
  2. Firmware compiles with no problems
  3. I cannot upload firmware ;-((( with error message:
    Arduino: 1.8.5 (Windows XP), Board: “Arduino/Genuino Mega or Mega 2560, ATmega2560 (Mega 2560)”

  1. When I am attempting to run Ground Controll - cmd widow flashes couple of lines and disapears…
    I am stuck - please help. I do not even know where to start debugging. I’ve checked all connections, latest versions etc. etc.

also don’t have ground control open when you upload

Welcome @TomD!

@Solomon_Bodrug is right, the Arduino program and GroundControl fight over the connection. It is best to quit the one then start the other. :+1:t2:

I had a similar issue. I solved it (sort of) by pressing the reset button on the Mega and releasing it just before uploading the firmware.

Google suggests that this issue may be due to FTDI firmware or other drivers. I don’t recall ever having an issue flashing a genuine Arduino or Mega, just the clones.

I think I remember that one when the boot loader gets corrupted by a previous upload. It’s more then a year back but I will dig. I might be totally off here, but I am often.
