Hi, I want to know what is the instruction for sleeping in ARM Cortex A8. I did execute a WFI instruction seems to be a NOP. void cpu_idle() { unsigned long tmp = 0; asm("b 1f\n\t" ".align 5\n\t" "1:\n\t" "mcr p15, 0, %0, c7, c10, 5\n\t" "mcr p15, 0, %0, c7, c10, 4\n\t" "mcr p15, 0, %0, c7, c0, 4" :: "r" (tmp)); return; } The above function doesnt seem to work. Please let me know exact instructions to follow.
