In fact it is not better with this config: #define CONFIG_ICACHE_ON #define CONFIG_DCACHE_ON #define CONFIG_SYS_DCACHE_SIZE 32768 #define CONFIG_SYS_ICACHE_SIZE 32768 #define CONFIG_SYS_CACHELINE_SIZE 32
My architecture is arm926ejs and it seems that CACHE management is not implemented...
I just measure a load of uImage (2MB) ... it takes more than 2 minutes :-(
Yes, this is really slow. Jean-Christophe will be able to tell us if caches are supported on this platform in U-Boot.
I've not yet find time to implement the MMU support for arm (needed for D-Cache support), I've plan to add it for the next release (not for this next merge window)
I-Cache is supported
but 2 mins is really slow, could show us your code?
