Kent, The old Motorola 68HC912B32 EVB had a small serial bootloader built in. It's probably part of the S-record file of the old 2.x versions of D-Bug12, which ran on the 912B32. If all you need is a binary, this would be an easy way to get going. If you can possibly hang onto the BDM pod or get one of your own, do it. For development, they beat serial bootloaders hands down.

Hey guys, Previously I've done a fair bit of work with various Microchip PICs in assembler, and am now looking to learn a bit about 16bit micros and C. I've been given a basic board with an M68HC912B32 chip on it, which basically has the crystal, rs232 level converter, and all other pins taken to a header. I'm also borrowing a 'Cable12' from P&E Microsystems to program the chip, but need to give this back in a few days. So basically I'm looking for some bootloader code for this chip so that I can keep working with it once I give the programmer back. After a bit of a search around the next and archives of this list, I can't seem to find any source or compiled code available, aside from app note AN1718 on Motorola's site. This has the source code in it, but doesn't translate very well when copied from the pdf and pasted into notepad :) My question is does anyone have source or assembled (.s19?) code for this or any other bootloader that will work with this chip they could send to me? Cheers, -Kent |
