I have downloaded the latest release and flown it with no problems in flight attitude. However, camera stabilization did not work. I attempted to reload the firmware manually through Arduino to insure stabilization was enabled, as I have done before, but this time I keep getting the same message after upload is completed;
avrdude: verification error, first mismatch at byte 0x1e000
0x36 !=ff
avrdud: verification error; content mismatch
The APM fails to initialize when I try to power it up in fly mode. I am using UAV controller V1.0, and I am supplying an additional 5 volts at 1 amp through a DC power supply while uploading. I tried doing the same with the newer controller board V1.4 Atmega 2560 and had no problem. My V1.0 controller board just doesn't seem to want to flash AC2.0.25 manually through Arduino after flashing through the Planner. I am a bit dumbfounded. Any suggestions?

Michaael the bootloader starts aat 0x1F000, there is a batch of APM boards with wrong fuses settings, I had the same problem. The fuses are set for 4kb bootloader instead 2kb.
Christopher you can fix it burning the right fuses as I did, take a look:
