Migrate 3430 to 3530,hangs at L2 CACHE is enabled in bootloader

I'm trying to migrate 3430 to 3530. It hangs at "L2 CACHE is enabled in bootloader".I've trace the start process,and found that it hangs at this place

 if (tlb_flag(TLB_V4_D_FULL | TLB_V6_D_FULL))

asm("mcr p15, 0, %0, c8, c6, 0" : : "r" (zero) : "cc");

This code is in function local_flush_tlb_all called from omap2_map_common_io 

what cause it hangs here?
