If I want to run Qemu ARM system to simulate a system without MMU (MMU less), how can I do?Thanks for your responses and best reagards, Tieu
Hi,according to target-arm/helper.c the MMU is enabled/disabled with coprocessor 15.
if ((env->cp15.c1_sys & 1) == 0) { /* MMU diusabled. */ *phys_ptr = address; *prot = PAGE_READ | PAGE_WRITE; } else { /* Pagetable walk. */ } It is disabled when QEMU starts... -- Thorsten
