Hi
I am using arm926ej-S processor and using the linux 2.6.27 kernel. If i enable the cpu DCACHE then the kernel is not booting up.
Can some one tell me is this because of some issue with the processor. I am using at91sam9g20 controller.
Is there some test application or test method which can be used to test internal data cache of the processor, to check is there is some problem with the processor's internal data cache.
Thanks

It's not clear whether you are enabling the cache within the Linux build, or before entering the kernel.
Either way, it's probably worth reading [url="
