Hello,

I'm using 89c66x microcontrollers and I'm working with since many weeks successfully.

However, I've an issue :

When executing accidentally Hyperterminal on the same COM port than FlashMagic during the Flash programming, first Flashmagic is unable to continue the programmation, but the problem is that I can no longer flash again the chip !!! It seems that the bootloader is unavailable.

I've currently 2 chips perfectly working in normal mode but unable to be flashed again.
Aaargh !

1. Why when the flash programming is corrupted I can't go again into the Flash bootloader ?

2. Is there a way to repair this ?

Regards

Stephane
