Program State red blinking

Im not sure...I think I did because I saw a small spark...but right after that...the program crashed and indicated infinit loop. recovery was not possible. Even the FORCE PROGRAM does not work, I just get a blinking Battery power LED and a solid Program state LED..Sigh.

A spark across what pins?

By the sound of it, you may have killed the user processor. (Although they tend to safeguard the processors pretty well, I think.) If the master processor is still operating but the user processor is dead, it might create the symptoms you are seeing.

Has IFI said anything yet?

1351's usual procedure for unknown blinking light problems:
1. Cycle power. Eliminates some hardware problems.
2. If that doesn't fix it, load default code. Eliminates problems with your code.
3. If that still doesn't fix it, reload master code. Effectively puts software back to factory state.
4. Call IFI. Never got this far before.

Your spark leads me to believe that it's a nasty hardware issue though.

i'm having a similar problem....see my post in the 'control systems' forum...

I'd be inclined to agree with that. Short protection can only do so much for microcontrollers, their IO pins are only really meant to source low current draws (typically less than 100-200mA). What voltages are you using it with? If you have greater voltages on board than the RC's logic voltage and they got shorted onto an input it could very easily blow it out. I had this problem about a month ago in one of the designs I was working with where a 12V line got shorted onto the 5V bus taking out two micros and an LCD, even though the short was only for about 1-2 seconds. I hope you get it fixed but from the sound of things it may not be doable unfortunately.
