bootloading to a multi-controller board

[NavMicroSystems]

Yep for sure... but since you boot the PIC, all pins are set to input, IMO the booloader software set TX to output itself.

I always set the registers "manually"

AND the link was about ICD problem, not bootloader problem(like i had few days ago... still feeling cheap of my mistake ;o] )

My reminder was just ment to make you smile ;-)

BUT... i'm not sure HSEROUT will work after that. AND case it's working... all TXs are tie together without any kind of isolation... short circuit's coming soon

I fully agree. when connecting pins that have a chance to come up as output there should be some kind of protection (like diodes)

AND i'm really not going to use this kind of method. i'll prefer using one bigger PIC.

I also agree on this one, but sometimes there is no choice, since the PIC is only able to do one task at a time.

You can get some kind of "multi-tasking" by adding some PIC's .
