Assembly only example?

Other Parts Discussed in Thread: TMS320F28027

I'm interested in starting an assembly only project on a TMS320F28027. Does anyone know of any examples of a bare metal asm only startup on this device? I have a bit of experience doing this on ARM, but this is a different beast. Thanks.

I should note that I have the documentation and am studying it. One of the main tricks with getting an ARM Cortex started is seting up the interrupt vector, I assume it is similar on the C28x. I have generated the asm for the provided samples, but they are full of attributes and other cruft, makes it hard to sort out.

I have a linker file setup and can now hit a breakpoint in a simple asm file. I understand the basics of the boot rom and the vector at the top of flash, so I'm making some progress. Now I need to get the PLL configured and start the UART. The data sheet seems a little slim (but I'm sure everything is there) any tips or examples would be awsome. Thanks.

Mark,

I'm not sure how much of a help this will be, but the attached code is a short assembly program which (I think) runs on F28027. I can't guarantee anything so please just treat it as a reference.

Rename the .txt file with a .cmd extension.

Regards,

Richard

Oh man, this is really great. Thanks alot! At a quick glance it looks like it might be for a different board, but I will make those changes and see if I can get an led blinking on the launch pad.
