First, I need to apologize to the PIC CAN group for my silence.
I have been busy with Family issues and personal health issues.
There have been new requests to the group that have gone unanswered (so =
far)
I hope to catch up with everyone soon.

Re: CAN Bootloader. Ther App Note includes software written in VB that=20
No-one (To my knowledge) has been able to get running. I've been=20
talking with the author at MC and I'm really not sure if there may be
an update or not.

I am working on a platform-independent can bootloader that basically =
uses
the node that connects the PC to the CAN net to do all the grunt work.
This could accept text commands and plain ASCII .hex files for =
distribution.

All you'll need on the PC side is any terminal program,

That's the plan, anyway. I hope to resume work on it soon.

Wouters comments that the boot code should be independent of the program =
are
well taken. I'll do that as much as possible. However, my application =
will require
the command to enter "Boot Mode" to be issued over the CAN bus. I won't =
have
physical access to the nodes being re-programmed.

Once I have a working project, I plan on posting it all to some web page
(possibly PICLIST.com, if available) for public ridicule. As a CAN net =
starter
project.

More details will be posted as I get it back together. Heart attacks can =

change your priorities very quickly.
