I'm sorry, but I really don't understand what you're asking about. Both u-boot and Linux run on the ppc405 cores that the Virtex-4 uses. However, there is no cache coherency between the cores so you would need to run a separate Linux image on each one. (SMP doesn't work) Cheers, g. -- Grant Likely, B.Sc., P.Eng.
