Programming MV2 cpu

[Gixfighter]

Hello guys,

I would like to modify the standard MVII code, which is already in the CPU. Now, I searched a lot (too much I think) on the forum, and now I'm a bit lost. I've got some questions about modifying and downloading the code into the CPU to make sure I'm not putting a lot of time into something without progress:

1. After modifying the code, which is done in C++ in my case, I can just save it as a *.c file right?

2. I need to compile the *.c file and create the S19 file, correct? Software used for that is called 'Codewarrior'? Or is there any other software to do this job?

3. I need to download the code into the CPU, but do I need a willet or any other programmer to do this, or is this bootloader code already in there because the cpu already has the MVII code in it?

Thanks a lot for all the help and suggestions!

Regards from Holland

You need to get either CodeWarrior or the GNU equivalent for the HC08, create a project, and put and modify the MV2 code inside that project. That will give you an s19 file. Then you need either a bdm cable or willette programmer to download the s19 file.
