programming issue about brushless-gimbal HOT 13 OPEN

I have the same or similiar issue.  I can't get the GUI software to work on v48 
and Arduino wont upload any of the firmware or a bootloader.  HELP!

Its' possible you may have v46 flashed to your controller card. I found that 
the new USB driver from FTDI is not compatible with some v46 flashed cards on 
some Windows XP systems. Delete the FTDI Driver version 2.08.28 on your 
computer. Load previous version 2.08.24 from 
http://www.ftdichip.com/Drivers/VCP.htm website on to your computer. They have 
an executable file if you need. Now open Arduino, with the v48.ino and flash 
the new firmware to you card. You are now ready to program with the latest v48 
GUI.  

I have same issue , I have changed FTDI driver to previous version 2.08.24 , 
can't solve the issue. HELP!! Thanks....

I haven't solved it yet, but will report the problem asap!

I assembled 3 pcs of the board ,all of the board are same issue . please help !!

Any body can help me !! I still can't download firmware from USB. 

I'm using FTDI Driver 2.08.24.0. FTDI Driver 2.08.28.0 does not work for 
Arduino or GUI on my XP laptop.  Had v48 loaded and and able to change PID 
parameters, etc. and saved to board. Downloaded and loaded v49 to board. Now 
when I try and change any parameters PID, max PWM, RC-Min, RC- Max for both 
Pitch and Roll and click save values from gui into board parameters are not 
saved to board, however I do sometimes get the ERROR: error flushing 
"filef77a58": permission denied when triying to save GUI setting to board.

PLEAS HELP ME!!!

To anyone who has issues with connecting to the board, the FTDI driver version 
that you should use is 2.8.14.0. You can find it in the windows update archive:

good luck

I have just successfully changed the Arduino code and flashed the card...I have 
also managed to download the GUI and made that work with the card...founf -46 
to be Fully functional whereas some components of v -49 failed to 
work....Gimbal is working fine...with some exceptions that the motors do not 
hold DURING flight./....works fine on ground...have tied shock mounting the 
gnbal ut it just constantly drives the tilt .... Question...DOES the BOARD have 
part of the IMU on it and DOES the bard have to be Horizontal and in Line with 
the gimbal... 

I just manage to download firmware
choose from arduino "Arduino mini w/ ATmega 328" no 5V version
programmer "AVRRISP mkII"

I have programmed but if I remove the board from my computer.
board does not work and the green light flashes quickly
