Random problems in MCB900 & FlashMagic - Hitesh Mahant - Mar 29 5:45:00 2005
Hi friends,
Anbout six month ago when I started using LPC9xx chips with MCB900 and
FlashMagic, I had taken good help from many of you. Since then I have
been using these two tools to program LPC922 CPUs. I have observed some
typical problems. And some clue-less solutuons too.
I have P4 machine and windows98 OS
MCB900 v4 on COM1
Flashmagic V2.07, DLL v1.74
Target CPU (LPC922) connected through header, chip on MCB900 removed.
Problem: Sometime all of a sudden FlashMagic stops communicating to
target CPU. After many retries it never succeed. Just like CPU suspected
failed. Repowering of MCB900 or reloading of FlashMagic donot help.
Sol-1: After complete reboot of system, it works normal. Sometime this
also donot work.
Sol-2: When sol-1 donot worked, I removed failed target CPU and
connected a fresh-one, FlashMagic loaded successfully. After that again
I connected suspected-failed CPU, that also worked. And I could
reprogram it many times, and still its working.
This behavious I couldnot understand. But still, it works. So I am
sending this case study to forum.
With warm regards.
Yours truly,
