Hi,

Hi Igor,Danny, Luke,  and all.
Have you run Hello World (from the software tutorial) on a Xilinx 
board/FPGA ? I have now switched to jp2, after downloading new debug 
interface and jtag module and that seems to work fine but the gdb gets 
stuck after I try to download the code. This is the message I get on the 
jtag window

JTAG ID = c388a928
Dropping root privileges.
JTAG Proxy server started on port 9999
Press CTRL+c to exit.

After I  set the target to JTAG in gdb I see the following messages

set_chain 1
set_chain 4
rr 4
wr 4
rr 4
rr 4
wr 4
set_chain 1
rr 1
set_chain 1
rr 1
set_chain 1
rr 1
repeats several times

Now, when I try to load the program.... the JTAG window starts
giving message 

JTAG ID = c388a928
RETRY
RETRY
RETRY
RETRY

and while the gdb window gives the message loading and gets stuck 
there . Any idea whats going on ? Any tips would be appreciated.

Thanks again

Farhan
