Re: [Xenomai-help] Xenomai beagleboard xm ethernet working!

[David Wiebe <dwiebe2@domain.hid>]

Hello,

In menuconfig, unselect realtime clock. lol! Boots fine, ethernet 
support works! I also patched the kernel to support spi which works in 
userland.

Now to make it all work as a rtos. If anyone has suggestions or 
whatever, I need to work on a spi to ethernet bridge. I need to read 
360bytes every 1mS and send it out over ethernet. I've done this with a 
non-rtos and achieved 360byte read and send every ~740uS. The problem 
was sometimes it would vary between  700 and 900uS etc. I need this to 
be isochronous and 1mS will work fine.

There you have it!
Cheers!

David
