OpenOCD 0.2.0 Win and LPC2148

I have some problems getting openocd 0.2.0 to work under windows with my olimex LPC-P2148 board (http://www.olimex.com/dev/lpc-p2148.html). I am using a Olimex ARM-USB-TINY JTAG interface. I first have this problem:

C:\PROGRA~1\OpenOCD\02225D~1.0>openocd -f interface\olimex-jtag-tiny.cfg -f targ
et\lpc2148.cfg
Open On-Chip Debugger 0.2.0 (2009-07-18-09:50) Release

jtag_speed: 3
RCLK - adaptive
jtag_nsrst_delay: 200
jtag_ntrst_delay: 200

Error: JTAG tap: lpc2148.cpu              got: 0x9f3f1f1f (mfg: 0x78f, part: 0xf

Error: JTAG tap: lpc2148.cpu  expected 1 of 1: 0x4f1f0f0f (mfg: 0x787, part: 0xf
1f0, ver: 0x4)
Error: trying to validate configured JTAG chain anyway...
Error: unknown EmbeddedICE version (comms ctrl: 0x80000000)

When i change lpc2148.cfg (“set _CPUTAPID 0x9f3f1f1f”) i get:

C:\PROGRA~1\OpenOCD\02225D~1.0>openocd -f interface\olimex-jtag-tiny.cfg -f targ
et\lpc2148.cfg
<cut>
Info : JTAG tap: lpc2148.cpu tap/device found: 0x9f3f1f1f (mfg: 0x78f, part: 0xf
3f1, ver: 0x9)
Info : JTAG Tap/device matched
Error: unknown EmbeddedICE version (comms ctrl: 0x80000000)

Right, to the device is now correctly detected, but: The EmbeddedICE version is unknown. When i do a telnet localhost 4444, the following happens:

Open On-Chip Debugger
> init

JTAG tap: lpc2148.cpu tap/device found: 0x9f3f1f1f (mfg: 0x78f, part: 0xf3f1, ver: 0x9)

What can this problem be? Thank you very much

Actually, I think the id should be 0x4f1f0f0f but because the comms is faulty it is returning the wrong id. Changing the id won’t fix the comms…

I would change your config to remove rclk setting, and set jtag speed to no more than 1000 khz.

You appear to be running 0.2.0 version of Openocd but are using 0.1.0 scripts?
