I have included links to 2 videos that show that demonstrate some unsusal behaviour
Start LED and Tones on a Pixhawk loaded with Rover FW 3.2.2
End of FW upgrade tones when uploading FW 3.2.2
The tone “de dar dar” is not noted on the general list of Pixhawk tones.
I am using a genuine 3dr pixhawk 1. The normal tone was being generated by this pixhawk before the upgrade. I have another Pixhawk 1 on FW 3.2.2 and it play the normal tones on start up
Any comments are welcome
If you have a safety switch can you connect it and hold it down as the board boots up? This will force the I/O firmware to load. The other thing to check is that the SD card is inserted correctly.
I tried the safety switch.It did make a different series of sounds. However when I rebooted without pressing the switch it reverted to dee dar dar
I will try the SD Card now
