I am having problems with my new APM2.
After waiting for a month I finally received my new AMP2 board April 9th. I have managed to hook it up and install the firmware and do the initial setup. The problem is that when I try to boot up with the battery it fails to start. Just sits there with a Blinking 3DFIX and a green power LED. I have power coming in on #1 of the output rail.
If I hook up the computer first the unit boots then attach the battery and remove the USB cord it stays running. I am able to arm and disarm the motors. When I power down and retry it with the battery nothing.
If I pull the sd card it will boot. I have tried to erase the SD card through the console but the same problem after the erase.
This board came to me assembled and tested. Why should it have a problem like this if it was tested first. Unless the testing was only done with the USB cord attached.
