New PPC Port

Posted by Kevin Sweeney on June 11, 2013
Hi All,

I am considering having a new Power PC port created. Specifically, the MPC56xx line. More specifically, the MPC564xA/SPC564A family using the Freescale/ST Micro dev board.

I would consider paying for the port and having it be added to the officially supported ports of FreeRTOS, depending on the cost of course. And of course if the maintainers were interested.

The problem is that I have no idea of how to start this effort.

So the question is; how would I start?

Any thoughts or guidance would be greatly appreciated.

Yes...the maintainers would be very interested, but unfortunately we are working flat out on new developments at the moment so time is a scares resource and adopting ports is a time consuming exercise (testing, updating, quality control, documenting etc.).

Depending on your budget, you could contact the folks at High Integrity Systems to see if they could assist as their safety work takes them more in the the PPC world.

How different is the device to the existing PPC4xx ports? Maybe you could start with the source code for one of those? There is a little bit of help in the porting guide, but there is not really any generic text that can be written about the guts of any particular port as how the port is written is very dependent on the functionality of and facilities provided by individual CPUs.
