Hi all,  

Does anyone know how to enable the eCos SMP support to niosII processor? 

Is that possible? Is there any article about that? 

 

Thanks, 

Maikon.

Currently there is no SMP support for Nios II. You can find details on what would be required to implement it in the eCos reference manual. You will find a copy of this in your installed version of eCos. You can also find a link to it here: 

 

http://ecos.sourceware.org/docs-2.0/ref/ha...mp-support.html (http://ecos.sourceware.org/docs-2.0/ref/hal-smp-support.html

 

The important feature to note is that eCos requires coherent caches. In the case of Nios II, this means that you will not be able to use either an instruction or data cache on any of the processors in the system.
