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
interface parport

Please for help. Thanks in Advance.
