PowerPC Assembler only project

Bloodhound — Thu, 26 Feb 2015 23:55:36 GMT

Hi All,

I need to do a small project for an e200z760 core device (MPC5676R) that needs to be written in VLE assembler, but it seems Code Warrior is very much C orientated.

Is it possible to create a minimalist project that does nothing more than call the assembler code without it adding in a bunch of C starter files to the project? (I have CodeWarrior for MPC55xxMPC56xx v2.10 installed).

Thanks.

Hello Ross,

You can create MPC5676R project in the Project Wizard and remove/delete all source files.

Then you can e.g create and add to project:

__startup.s file which includes __start routine ...this is where you can add your startup asm code. It jumps to main_asm() at the end.

And main_asm.s this is where you place your main code.

You can create your own project structure - this is just an example (see attached project).

Hope it helps.

Stan
