Did I brick my LPC1768?

I’m using Yagarto/Eclipse/Flash Magic.

I have a LPC1768 Blueboard. When I first got it, it had some kind of code on there that flashed the LED. I loaded my own code to do the same, and it now doesn’t seem to be able to vector off and run.

I talk to it through Flash Magic. I can talk to it through a serial terminal and issue the Synchronized and crystal commands, however I’m not seeing anything on the scope at the crystal, and the LED doesn’t blink. In fact both LEDs seem to go to an intermediate state and I’m reading 1.7V.

I haven’t hooked anything up to the board that I would consider to have caused this. I tapped into the USB power (That is how I’m powering it, through USB) to get ~5V over to my level converter.

I’ve uploaded another hex file I found on the web and it does the same thing.

Is it how I’m using Flash Magic maybe? Is there another program I should try? It has worked for me in the past with the LPC2138. My experience with that chip was that when I fryed it, it was truly fryed and I couldn’t load code or anything else.

I’m getting a fresh board delivered today, but I don’t want a repeat.

On the new board use Flash Magic to capture the image on the board before you try to program it yourself.

The fact that you get Synchronized back, is a good sign, at least the ISP is still running. In fact take that file you captured and try downloading it to the old board.

There are lots of ways to go wrong with the initialization code, and the part will just look dead.
