Jun 09, 2006 9 Replies

hello i built on myself a cable 3 interface,following the xilinx drawing,i checked in all the possible ways,ohmically,injecting square waves,and then once connected tho the parallel port i used the option in the Jtag programmer utility that allows to force level on tdi,sending n clock pulses and so on,these signals are present on the pins of the fpga and the cable is connected to the supply(5V),but the pc doesn't see the cable at all please,anyone can help me?thanks!


checked

Try the different BIOS setup options on your computer for the port in question. It worked wonders for me, but that was a Parallel IV cable. When it was set to ECP-mode, everything worked so much better.

despite here in italy are 1:45 a.m. i want to follow your hint,stay tuned and thank you

Well, try to change the port. My Cable IV would not work at all on my "expansion bord" LPT, but it worked on my mainboard LPT. Maybe the opposite is the case for you ?

looks like you have a choice in Italy. More than we have in the UK.

Digilent sells a clone of the Cable III quite cheaply. I got one with their Spartan 3 kit.
