What steps will reproduce the problem?
1. Version 0.49 r69 firmware
2. Martinez brushless gimbal control board

What is the expected output? What do you see instead?

GUI should be able to read values but instead it gets stuck at PAR:Reading 
Values or something along those lines.

The board can no longer have firmware uploaded to it by arduino, gets the error 
"avrdude: stk500_getsync(): not in sync: resp=0x00"

What version of the product are you using? On what operating system?

Windows 7, 64bit, with driver fix (here 
http://www.rcgroups.com/forums/showthread.php?t=1872416)

Firmware version 0.49 r69

Please provide any additional information below.

Was working fine on 0.49 r45, uploaded to 0.49 r69 without problem, but shortly 
after the board would no longer communicate with the GUI.

Many others are having this issue as well (see posts on these last couple of 
pages http://www.rcgroups.com/forums/showthread.php?t=1829058&page=149)

Reflashing the bootloader and reuploading the firmware fixed this problem. I am 
now running the latest 0.49B r77.
