Hi, all:

     Now,we have transplanted fiasco to imx 51 bbg board. When we use l4_vm_run to init a 

NS world(refer to the example of vm-tz), the system stop in the step of "VM run". More specially,

we stop with the function of "tz_switch_to_ns" according to debug info. Following is our log info:

Vmm started 
Vm run

Our configuration is:
    Ram_base = 0x60009000, // The reserved address in imx51, l4sigma0_map_iomem() seems ok.
    Ram_size = 0x4000000, // 128 MB
    Start_addr = Ram_base + 0x1000000, // +1MB

  test.bin is bare uart test-app which tested ok in imx51 bbg, we set entry "0x60009000" 

corresponds with Start_addr.

Maybe we make some mistakes or some wrong understanding, can someone give some guidance and suggestion?

Thanks a lot!

Looking forward your reply.
