Hello Folks I need  Your help,

I started with the new Pixhack, Flashed the AC3.2.1.

After a successful flight I want to flash AC3.3-rc8, unfortunately I clicked OK before the Musik Tone was done. So I want to be sure that everything goes right and want to flash AC3.3.rc8 again. To do this first I had to flash Arduplane. Nearly after the Firmware upload was finished the Pixhawk start with the continuous tone and the USB was suddenly a "Unknown Device".

That´s It. I tried to reconnect the Pix without success!

the IO led toggels blue-red

the FMU led is white

the Buzzer has a continius tone

any idea what I can do?

Is there a chance to reload the IO chip with new firmware?
