I think I need something like this (I did not deeply inspected the code), but for ARM (examples here are for PPC). Similar to this example, I would first enable MMU ( call to a mmu_init() ), then caches ( calls to dcache_enable() and icache_enable() ), then do some read and write to a memory. Voila. I hope that then all R/W to memory will be faster because of support of DCache. If anybody knows where I can find similar example (or how can I modify this one for ARM maybe), help will be more than welcome. Best regards, Drasko
