This is true - most probably it would, although I never tried - to be absolutely sure, you can try to reset it by a clean pulse from some external source.


This depends on many factors, but might suffice. I rely on your experience here. Just one remark, to reduce the possibility of confusion, please use SI marking, 100 nF, or 0.1 μF (0.1 uF would do here on the forum).


This might be the root of the problem. The chip might go into the bootloader mode inadvertently.
Just try to disconnect Rx during boot and reconnect it after. If this proves our theory, I'd recommend you to go to the FlashMagic website and download the newest bootloader (v7) there (it's not available from NXP site). There is a manual included. The bootloader entry can then be bound to a status on a pin, or the bootloader can be then disabled altogether (if you have a true parallel programmer, you can do this safely).
Alternatively, if the parallel programmer is at hand and you plan never to use the bootloader, you can try to write a short utility into flahs Block1, which does nothing else just a sofware reset - which works so that it switches immediately to Block 0 and restarts from there.
