It seems that I have a chronic problem getting the GPS to lock in. Often when powering up with the PIxhawk, I get hdop 100 and 0 satellites. After waiting anywhere from 3 to 10 minutes, It may or may not begin working and I get a 3D fix. sometimes I just give up because It seems to be totally dead other than seeing the the red LED is lit.
I have tried another Compas/GPS module, but the same thing happens. I am using 1.58GB video, 1000 mw. Could it be overdriving the GPS?
I am using the Compass/GPS ordered with the PIXHAWK.
I also am unable to write the new beta firmware to the board. I am using the USB serial, and it usually will do the erase, then will begin writing but at some point the progress bar is showing that it is writing, but randomly will stop progress and then give a timeout error.
So it leaves the board dead, but I can then load and write the 3.1 current flying firmware and bring it back to life.. I have tried different USB cables, any ideas for me to try?
