OpenOCD and ARM-USB_TINY JTAG (olimex)

Started by zanakca March 25, 2010
Hello Community !

I'm trying to use a USB-TINY JTAG from Olimex with a custom board I made (lpc2148) using OpenOCD , but I get the message : Error validating JTAG scan chain , IR mismatach, scan returned 0x00.
I tested the same board with the Olimex JTAG WIggler using LPT port and it works well, I can access it using the OCD commander and with IAR workbench,
I tested the USB-TINY with an Olimex lpc2468 and it works well.

Do you have any Idea what is wrong ?

here is my config file :

#daemon configuration
telnet_port 4444
gdb_port 3333

#interface
interface ft2232
ft2232_device_desc "Olimex OpenOCD JTAG TINY A"
ft2232_layout "olimex-jtag"
ft2232_vid_pid 0x15BA 0x0004
jtag_speed 10

#use combined on interfaces or targets that can't set TRST/SRST separately
reset_config trst_and_srst separate
#reset_config srst_pulls_trst separate

#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
run_and_halt_time 0 30

#target_script 0 reset oocd_flash2138.script
working_area 0 0x40000000 0x40000 nobackup

#flash configuration
flash bank lpc2000 0x0 0x40000 0 0 0 lpc2000_v2 20000 calc_checksum

Thank you.

Hi,

have you tried to use the configuration files of OpenOCD?
The interface section is correct for the Olimex ARM-USB-TINY,
but as far as I see ../tcl/target/lpc2148.cfg has some differences to
your configuration.

Kind Regards
