I'm trying to setup OpenOCD 0.3.1 for debugging using an Olimex ARM-USB-TINY JTAG debugger and an Olimex LPC-E2468 development board.

I start OpenOCD (version 0.3.1) with the following command:
C:\Program Files\OpenOCD\0.3.1>openocd -f interface\olimex-jtag-tiny.cfg -f target\lpc2468.cfg

It appears to start successfully and displays:
Open On-Chip Debugger 0.3.1 (2009-11-13-16:13)

Info : Embedded ICE version 7
Error: EmbeddedICE v7 handling might be broken

The behavior is the same if I use a Signalyzer instead of the Olimex JTAG debugger.

The problem is that I can't halt the processor. When I telnet to OpenOCD and issue the halt command it fails:

Open On-Chip Debugger
- init
- reset
JTAG tap: lpc2468.cpu tap/device found: 0x4f1f0f0f (mfg: 0x787, part: 0xf1f0, ver: 0x4)

I have the same problem when trying to halt an LPC2106.

Others have commented on this, but I haven't seen a solution posted. Can anyone help? Start a New Thread

It seems my problem was that my startup code wasn't configuring the PLL properly. With the PLL and various dividers configured correctly, I am able to halt OpenOCD and debug as expected. Start a New Thread
