Re: use xilinx gpio from linux on a ppc405

["xavier.vvv" <xavier.vvv@gmail.com>]

Hi,
I have installed linux 2.6 on the xupv2p board. I have uart, ethernet, but
sysace device is not working.
I have seen in this forum that other persons have the problem.
Could you tell me if you have sysace driver working?
Also I want to install xenomai, but the problem is that linux from denx tree
does not support opb_emac ethernet 
driver. I need Ethernet because I use nfs to access the root file system.
So another question is: 
when you installed xenomai, where was the rfs? and did you used Ethernet
driver?

Thanks
