Ok, So I have my DP
and I am going to upgrade my debian. I have tried
windows - putty
linux 10.04 - gtkterm, putty, minicom, cu
linux 10.10 - still nothing
I have watched a video on it for windows and am certain I have followed the instructions correctly
My jtag lights flash but there hasn't been a single bit of output in any terminal program..
I need help
here is dmesg | grep tty
[ 9461.748846] usb 3-1: FTDI USB Serial Device converter now attached to ttyUSB1
I really want to upgrade and specifically bought the jtag for this and other tinkering purposes
plz help

For PuTTY on Linux your settings need to be as follows :-
Connection type: serial
Serial line: /dev/ttyUSB1
Speed: 115200
That should do the trick. I actually use picocom as its very small and easy to use. Install it on Linux then run it like this :-
picocom -b 115200 /dev/ttyUSB1
Hope this helps.
