Error validating JTAG scan chain

Development Boards MicroMod
1

Hi guys, I have an ARM-JTAG and an LPC-P2106-B connected to a laptop running Gentoo 64bit kernel 2.6.22.1, using an ExpressCard/34 parallel port adapter. The parallel adapter shows up as /dev/parport0, and I can use it successfully with some completely different program to bit bang a different board I have. This is what I get when I try to run openocd:

Info: openocd.c:92 main(): Open On-Chip Debugger (2007-08-10 22:30 CEST)

Error: jtag.c:1253 jtag_examine_chain(): JTAG communication failure, check connection, JTAG interface, target power etc.

Error: jtag.c:1440 jtag_init(): trying to validate configured JTAG chain anyway…

Error: jtag.c:1346 jtag_validate_chain(): Error validating JTAG scan chain, IR mismatch, scan returned 0x3f

Error: jtag.c:1448 jtag_init(): Could not validate JTAG chain, exit

And here is my config file:

#daemon configuration

telnet_port 4444

gdb_port 3333

#interface

interface parport

parport_port 0

parport_cable wiggler

jtag_speed 2

#use combined on interfaces or targets that can’t set TRST/SRST separately

reset_config trst_and_srst srst_pulls_trst

#jtag scan chain

#format L IRC IRCM IDCODE (Length, IR Capture, IR Capture Mask, IDCODE)

jtag_device 4 0x1 0xf 0xe

#target configuration

daemon_startup reset

#target

#target arm7tdmi

target arm7tdmi little run_and_halt 0 arm7tdmi-s_r4

target_script 0 reset h2294_init.script

run_and_halt_time 0 30

working_area 0 0x40000000 0x40000 nobackup

#flash configuration

flash bank lpc2000 0x0 0x40000 0 0 0 lpc2000_v1 14765 calc_checksum

flash bank cfi 0x80000000 0x400000 2 2 0

I am not sure that this config file is completely correct, but I think it should work to at least get farther than this. Any ideas?
