I have previously done some work on a 9S12C64 and found the serial monitor a more enjoyable environment than BDM. I recently got hold of a 9S12XS128 demo board, and would like to develop on it in the same way. Not that I'm doing anything earth shattering -- it's just a hobby.
I tweaked the easy to configure part of the monitor code (HCS12SerialMon2r1) so that clock rates, etc., were right. This worked, and I can talk to to the board from my client, but if someone else has done the work to support the different memory map, data flash, and other things I haven't thought of yet, I'd really like a copy.
I searched the forums already. There were a couple of promising leads, but they ended in dead links. I've probably missed something glaringly obvious.
