I have tried to compile the kernel by disabling the MMU, but it gives following errors during compilation:
In file included from arch/arm/mm/proc-arm926.S:36: arch/arm/mm/proc-macros.S:81:2: error: #error PTE shared bit mismatch arch/arm/mm/proc-macros.S:84:2: error: #error PTE bufferable bit mismatch arch/arm/mm/proc-macros.S:87:2: error: #error PTE cacheable bit mismatch I am a bit confused about disabling the MMU because AT91SAM9X has MMU support...can u make me clear about that?
