Ok, I've been working on this for 2 days now and I'm officially stumped. This is what I'm working with:
Arduino Pro Mini 5V 16Mhz w/ ATMega328 + FTDI Basic
I've tried to upload a sketch to it from 2 different computers, using 4 different USB cables. I have reloaded drivers twice. When I try to upload, the green LED on the Arduino flashes a few times and the red TX led on the FTDI flashes, but the RX LED on the FTDI board doesn't do anything and I get this error message: avrdude: stk500_getsync(): not in sync: resp=0x00
I tried the loopback test and got nothing, so I'm guessing this is a communications problem between the computer and the board somewhere, but I don't know how to narrow it down or fix it. Any suggestions? I've gone through all the troubleshooting steps and suggestions in other threads where this error message popped up and I don't know what else to try.
