Hi

I have just bought PCMCIA 2xCOM + 1xLPT Delock, but I can't program 
flash of AT91SAM7S256 - an error occurs:

'C:\Program Files\openocd-2006re82\bin\'openocd-pp.exe -f 'C:\Program 
Files\openocd-2006re82\bin\'at91sam7s256-wiggler-flash-program.cfg 
# program the onchip FLASH here
Info:    openocd.c:82 main(): Open On-Chip Debugger (2006-08-01 12:00 
CEST)
Error:   jtag.c:1122 jtag_validate_chain(): Error validating JTAG scan 
chain, IR mismatch

I used normal PC LPT and everything works fine.

My OpenOCD .cfg file is:

#define our ports
telnet_port 4444
gdb_port 3333

#commands specific to the Amontec JTAGKey

Please for help. Thanks in Advance.

Try increasing jtag_speed (higher values mean a slower rate), set it to 
10 as a start. Also make sure you choose the correct parport_port (check 
in device manager which I/O address your LPT card has).

That said, Cardbus/PCMCIA cards for parallel ports can be tricky. I once 
bought one for another parallel port debugger and never managed to get 
it to work. The safe bet would be to buy a USB JTAG.

The only pcmcia parallel device i ever got to work was one from quatech 
(SPP-100) - however they are not cheap.
It all depends if they emulate  a true parallel port - most do not.

As Andreas said go and but a usb jtag.

Hi

After restarting computer again everything goes good :).
Now it's working. The only change I did, was changing a line
parport_port 0xFFD8. I tried that before but not work.

I have one more question: Do you know how to remap I/O port OxFFD8 to 
Ox378,
becouse in some other programs I can't change addresses manually? I'm 
using WinXp.

Thanks for help.
