Error uploading to Mintduino

Hi all. I built myself a Mintduino and I'm getting error: "avrdude: stk500_getsync(): not in sync: resp=0x00" when trying to upload a sketch with a USB/FTDI board.

Here are the details...
Mintduino:

  1. The default "blinky" program works just fine.
  2. I was able to upload a new sketch using my Uno as a USB bridge using this method: arduino_clones:serial_adapter [Paper-PCBs] . This sketch operates just fine on the Mintduino both on breadboard and on my custom prototyping board I transferred the Mintduino to.
  3. Was originally thinking it was my custom circuit board that was the problem, so I rebuilt the Mintduino on a breadboard and I still get the same error. Again, program I was able to upload via the Uno worked just fine.
  4. I ordered some new 328P chips with bootloader and they won't take an upload either.

Other hardware/IDE:

  1. Windows 7 64-bit.
  2. FTDI board (this one: http://www.oddwires.com/ftdi-ft232rl-usb-to-serial-adapter-module-usb-to-rs232-for-arduino/
  3. IDE/device is set to COM6 and the same board as the other method I used that worked. Tried all the other boards too.
  4. I tried all manners of pressing the reset button before and during compile/upload.

I am stumped and getting frustrated!

Thanks for reading!

Problem solved...

It was the drivers for the FTDI board. Apparently the latest and greatest version 2.08.28 does not work. Downloading ver 2.08.24 from www.ftdichip.com fixed it right up!
