Im having issues trying to install firmware onto my autopilot computer. i followed the instructions on planner2.ardupilot.com/wiki/install-firmware/ and I’m getting a error message saying unable to open COM port.
Below is the output message I’m getting. Im using a macbook pro with the latest APM Planner v2.0.15.
Any help would be awesome.
Thank You.

You can check that your system is seeing the APM2.6 HW (I assume that is what you are using) by running System Information Application and browsing the connected USB device to see if it there. See image below
(It will look slightly different as my APM2.x was connected via a USB hub)
If you have tried it on other computers and you made sure the correct device drivers where installed if it was a Windows box. The issue is probably HW failure
As I sated here viewtopic.php?p=26981#p26981 It’s probably the APM2.x HW you are using has failed. Look-up 3.3V regulator posts as that may have broken.
