I am trying load a kernel in normal world, but the problem is it can not response on timer interrupt. I have set SCR, TZIC, CPSR properly, SCR.irq to 0, TZIC all interrupt as non-secure, CPSR.irq to 0. Did i miss anything? Why normal world can not response any interrupt? It doesn't goes into interrupt entry function.
