Thank you for your reply,

The problem was, that i used external voltage supply,
but only 5V. Board needs 9 VDC.

I have another problem.

Now, when i try to launch OpenOCD,
ARM-USB-OCD starts blinking green-orange
and in output console appear:

on first run, after start eclipse

I downloaded crossworks compiler, installed LPC2378 libraries
and when I try to connect, ARM-USB-OCD very shortly blinks and
remains shine orange.
Message "Target not responding" appear.

I have no idea what should i do or what im doing wrong.

Thanks for help.

I had the same kind of problems with the jlink adapter.
For me, upgrading openocd solved the problem.
Check if you can find a new version of the tools you are using or try
compiling a new one yourself.

Hi all,

I bought KIT LPC2378-STK

http://www.olimex.com/dev/lpc-p2378.html

and OLIMEX ARM-USB-OCD

http://www.olimex.com/dev/arm-usb-ocd.html

I installed enclosed Software pack with
Eclipse, OCD and YAGARTO,
and then installed drivers.

Now, when i open lpc2378 project in eclipse, build it
and try to run OpenOCD, this message appear:

And ARM-USB-OCD Led goes from green to orange.

Knows anybody, what does it means?

I am new in ARMs and I need help.

Thanks.
