Homncruse:
The warnings and errors when OpenOCD starts up concern me, but I can’t find anywhere in the documentation that actually says how to resolve situations like that.
Generally, it won’t work after the first error/warning, so don’t ignore them!
In this case I think you need to specify a target config file for the LPC2368. There doesn’t appear to be one in the openocd library, so you will need to find or create one. I guess one of the other LPC devices will be a good starting point.
