Thanks for the responses! I think the Matt guessing is a good starting point, also in page 26 of the schematics says that to debug the ppc you need the halt signal, my jtag programmer has it but I am going to take a closer look there.
I had seen the binging up doc, but I had the feeling that it suppose that you have the uboot running, they even configure the eth so they have access to the os. Like I erased the uboot, the USB doesn't have a loopback so I don't see any response there :( Anyway the ftdi should still work and I should be able to run the scripts (crossed fingers) I also found some info about the xmd connection of the ppc in the edk reference manual, and it says that for certain configurations the jtag doesnt recognize the ppc as a xilinx device, so the user has to explicitly define it to be recognized. So maybe I am in that case.
