#99436 - Thank god for the response
Responding to: ???'s previous message
Finally, I know I am not alien :).

Ok, Erik, FlashMagic, Flip are great programs but I cannot use it.

From my previous post earlier on, sorry for not mentioning, I am doing multi processor communication using Tx/Rx, Tx2/Rx2.

Device1 -- Tx/Rx --> Device2 -- Tx/Rx --> ... nDevice

So, I need to update all of them in a daisy chain method, instead of 1 by 1.

Craig,
1) My interrupts are off before I call the IAP.

2) Good suggestion for LJMP 0x3600 at 0x0000. I was worried about this earlier. Will definitely implement this.

3) I am not sure of writing over my flash routine at 0x3600. If I write something stupid there, I will have to reflash all my boards (about 1000 pcs). I will test this out.

Ok, back to my first question. Why does decrementing-address flashing works, and incrementing-address flashing does not work?

I am still puzzled :(.
