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:
- The default "blinky" program works just fine.
- 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.
- 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.
- I ordered some new 328P chips with bootloader and they won't take an upload either.
Other hardware/IDE:
- Windows 7 64-bit.
- FTDI board (this one: http://www.oddwires.com/ftdi-ft232rl-usb-to-serial-adapter-module-usb-to-rs232-for-arduino/
- IDE/device is set to COM6 and the same board as the other method I used that worked. Tried all the other boards too.
- I tried all manners of pressing the reset button before and during compile/upload.
I am stumped and getting frustrated!
Thanks for reading!
