Hi all, in order to enable data cache in U-Boot on ARM926, I have set up MMU to map all 4GB region directly (fixed mapping) and created a U-Boot command that will do all pagetable settings and switch on MMU and caches.
However, when DCache is switched on with WRITETHROUGH or WRITEBACK policy, U-Boot stucks. Switching on only MMU and ICache works well, so I presume that pagetables were correctly set. Does anybody have idea what can be wrong here? I tried invalidating both caches and TLB before and after turning on DCache, but I get the same result. Best regards, Drasko
