Adding a new target architecture

Adding a new target architecture

[Michael Stickel]

Hi,

is there any documentation on how to add a new target architecture 
(openrisc and sparc)?

The poky-handbook states in chapter 3. that it's not part of that 
chapter and there is no other chapter explaining porting to a new 
architecture.

Thanks
Michael

We don't have specific documentation on new architectures, but it should just 
be an extention of adding a BSP, so see the BSP guide for general stuff:

http://www.yoctoproject.org/docs/current/bsp-guide/bsp-guide.html

You may find the tune files in meta/conf/machine/include/ instructive as well; 
you could also use some of the other BSP layers as examples since some of them 
add support for architectures that aren't supported as part of the core.

Cheers,
Paul
