 To program the Bitstream use following command:

+$ sudo djtgcfg enum
+$ sudo djtgcfg prog -d Atlys -i 0 -f leon3mp.bit
 
 If you want to create your own Bitstream you need to get Xilinx/AMD ISE 14.7 for Linux.
 For that you also need a free License from Xilinx/AMD.
 
 To upload a Linux Kernel (f.e. with NFSRoot enabled) you need to convert the
