Looking for an OS with support PPC405 FPU

 

Hi. There are a lot of OSes for PPC405, but it seems they don't support FPU. May I use xilkernel for this purposes?

I don't think so. Here is why: http://www.xilinx.com/support/answers/31607.htm

It means that I can use FPU in one thread. And in future project with PPC440 I can't use xilkernel. It is very inconvinient

Re: Looking for an OS with support PPC405 FPU

We were planing to use Virtex-5 FPU with XilKernel. Then I saw this thread and the AR. Since both XilKernel and Virtex-5 FPU are product of Xilinx I have never thought that they won't work together. Technical support also confirmed this.

It is very strange.

And I can't find any info in the Xilinx's documentation about this situation.

But, BlueCat Linux of LynuxWorks supports PPC405 FPU.
