thank you very much to all of you for your help. From the start i
thought that kind of connection would never work hehe, but i always
say that is better to ask, now i'm getting a JTAG USB device.
Thank you :D

Those who wish to stay with legacy technology will have to get a hardware
parallel port.
On laptops with a PCcard/PCMCIA port can use on of these:
Instead of wishing for a legacy solution, just get a USB jtag now and not fool
with it any more.

Even if you get a parallel port (for example through a PCMCIA add in card) for
your laptop you won’t be happy with the reliability of parallel port JTAG
wigglers. I have a drawer full of parallel port JTAG wigglers from a variety of
manufacturers and none have worked consistently. For a modern system, get one
of the many USB-to-JTAG adapters:
These range from $30 to $105. I have personally used the Olimex and Amontec
USB-to-JTAG interfaces successfully with OpenOCD on Atmel AT91SAM7 parts. In
production where there is one static script that programs my boards I use
Amontec (a mix of tinys, JTAGS, and JTAG-2s). On my desk for development I use
an Atmel SAM-ICE because the SAM-BA GUI works well for the variety of different
things that I might do on any given day. For other options Google “usb
jtag arm”.
I like the idea of the Open JTAG units (such as the ecrater unit above) because
it has a serial port integrated into the dongle that you probably want for your
console as well.
Enjoy,
Bill.

The USB to serial cable you have will not work. The wiggler is designed to work
with a PC parallel printer port, not a serial port.

Docking stations for laptops often have the necessary, but are
incredibly inconvenient - IMHO.

This is the biggest problem about the latest laptops which are running around
now a days, most of the cheaper or even mostly expensive one's will never
provide a PC parallel port. You either have to get an older model laptop or a
different type which provides parallel port, but this could then cost you !

What you have setup will never work. Its like you are trying to hook up a Car to
a railway carrige and then expecting it to work, It never will.
1. Jtag wigglers, use a 25pin parallel centronics printer port, a USB centronics
printer almost certainly not port will not work becuase it will not replicate a
centronics printer port fully. The Jtag wigler uses some pins as inputs etc
which the USB adapters can't do.
2. You have used a 25 pin to 9 pin adapter, this is for serial ports which is a
completely different type of interface
3. You are using a USB serial adapter which is a completely different type of
interface. A serial port is NOT a parallel port.
You should look at using a USB Jtag adapter, of which there are many types. As
you want to use OpenOCD choose one which is supported by it maybe one of the
Olimax devices http://www.olimex.com/dev/arm-usb-tiny-h.html

I doubt that it will work. The USB<->DB25 adapters do not provide the
flexibility the old Centronix port gave.
It is often just the USB printer-profile.

If anything, then this option.

I think, you need a USB wiggler or if you have a PC, get a card with a
real Centronix port.
