I had a similar issue. I found that connecting an FTDI directly to the GND, VCC, TX, RX pins and then I was able to get serial IO.
I have to say, it took a bit of time to get this working, but I finally was able to.
Some issues I had: when using the Beefy3 FTDI board, I was only able to see serial output using the Arduino serial monitor. In order to use other terminal programs, I had to connect a UART to VCC, GND, RX, TX and then I could get serial out.
Also, I found the LED builtin pin was #2.
No public wish lists :(
