Re: [Xc3sprog-users] Programming the Digilent Genesys 2 board

Thanks for the reply, Uwe.

This it the output from `dmesg` when I plug in the board.

```

xc3sprog's behavior is the same when running as root. This is the output
running as root and specifying the reported serial number for the board. 

```
$ sudo xc3sprog -c ftdi blink.bit -v -s 200300730484

I am able to program the board using the Xilinx tools, so I don't think
that the board is faulty.

Best,
Joe.
