Hi, I can't start up the kernel(linux3.18) on imx283.

i have open the CONFIG_DEBUG_LL and could use the printch to output some stuff on the serial port, 


but, after it enable mmu, 


mcr p15, 0, r0, c1, c0, 0 @ write control reg
mrc p15, 0, r3, c0, c0, 0 @ read id reg


i can't use the printch anymore, 


and i find that, the kernel don't run to b start_kernel, 


now , i don't know how to debug this,
