Hello,

There is also the project called Podex originally created by Marek Peca
(http://www.duch.cz/podex/) and improved by Michal Konieczny
(http://cml.mfk.net.pl/podex/).
The Podex is protocol compatible with the BDM12 Pod by Kevin Ross
(http://www.kevinro.com/products.html).
You can use the NoIce debugger (http://www.noicedebugger.com/) for
programming and debugging or the Michal Konieczny's hc12mem
(http://sourceforge.net/projects/hc12mem/) for programming.

Hello Javier,

I can also advise you to build the Open Source BDM for S12.
The source files, PCB and schematics are available from Freescale Forums:
http://forums.freescale.com/freescale/board/message?board.id=TBDML&thread.id=2
There is a whole board dedicated to this mature project called Turbo
BDM Light or TBDML.

Cheers,
Alban.

To program the flash without a BDM you need a program running internally that allows you to do so, but to get that program into the machine you need a BDM, chicken/egg situation unfortunately.

The good news is that you have to borrow a BDM only once (or buy a demo board with a monitor preprogrammed in already)

Cheers,

Theo

I'd like to know how to program the flash memory without using an commercial
BDM cable.
Thanks very much.
Javier.
