after that i hvae jtaged 2 xenons i went over to jtag a falcon
the prob is that no matter what setup i try it never dumps or fully dumps
tried with all types of wires, connectors, dioeds, each time its a different problem
no flashconfig, or after it dumps halfway it has an eror in every block
im just loosing it
i think i tried everything
spent over 11 ohurs on this s**t ..
so m question is:
if i will try to dump it via the olimex usb header board
would it work better?
cuz i think it this stupid lpt protocol that giving me problems

no thats not normal. check your wires. I find that my setup which is pretty "rat nessy" like. You will get Tx errors if you use Lpt method. think about it. Old tech and longer it's transmitting more likely for data corruption. You have to redump and move the wires around and make sure ground is still connected.

When I got 70 + errors its because my gnd was partly loose.

A little history of what led up to it.
It(gnd) got unsoldered from countless bends and wiggles. I disconnected and connected my lpt plug from the back of computer like 5 times. I flashed nand and went to my living room to test it. Each time I plugged it back to my computer to go for another round of flashing the wires were misaligned again. You gotta iwggle it.

It worked for me so that's what I tell everyone from now. Check your ground if getting unreasonable errors. If you're using USB method then you might want to look for other areas of fault. I don't know about the USB method. But generally the first step is the physical...so look for that.

so what should i basiclly do?
and what do you exactly mean by ground?
i resoldered everything like a million times
so the question is what do you mean by ground?
which soldering point?
a picture would be nice

thanks

so does anyoe know if the olimex usb headerboard will work better?
and do i need to install anything else with it?
like the resustors and the diodes?
and how long should the cable be?
