I've been playing around with one of our prototype boards coding up some of our peripherals. Everything has been progressing well for a month or so. I was playing around with the different clocks, and I think I locked up the LPC. I think my code got my clocks in some 'not so good' configuraton. Now, my JTAG says ULINK - Cortex-M Error, Device could not be powered up. I've never seen this before, so I think I screwed up one of the clock registers. Is there a way to reset the LPC back to some factory default, so I can get the chip unlocked? Or any one have other ideas?
