Pixhawk locked up, wont boot, no tones with upgrade

My Pixhawk has been working working well, and has been flown successfully using 3.1.1rc1…

problem:
When downloading 3.1.1rc2 FW the pixhawk in MP 1.2.93, I saw the “erase” message, then went into the unplug-plug in sequence. Then got the error message “error: timed out”.
now I am not able to get musical tones, the switch light is constantly blinking red, B/E and Act leds are constantly blinking and the multicolored LED never comes on… I can’t get any response with usb nor onboard battery… I can’t connect just dead…

How do i get this fantastic controller working again?

With repeated attempts reloading 3.1 FW, I didn’t get the timeout error and got a successful load with the yellow blinks and musical tones again…

" If at first you don’t succeed, try again"

It sounds like the planner did not see the com port. Enable the console window in the Help screen.

Are you using MP in a virtual machine? Some times the com port is slow to be recognized.

Hi Craig,

Yes I am using windows as virtual machine in parallels… I will watch the console window next time…

thanks for the input.
