Hi,all:


      Now,we have transplanted fiaso to imx51 bbg board, when we use l4_vm_run to init NS world

(according to example of vm-tz), we found the system stop in the step of "VM run". More specifically, 

 we stop with the processing: 

"return l4_ipc(vm, u, L4_SYSF_CALL, *label, l4_msgtag(L4_PROTO_TASK, 3, 0, 0), label, L4_IPC_NEVER);"


The log info can be described as following:

[0:90000000;90000fff]

Vmm started  
VM run 

Our configuration is:

    Ram_base = 0x60009000, // The reserved address in imx51,l4sigma0_map_iomem() looks OK.
    Ram_size = 0x4000000, // 128 MB
    Start_addr = Ram_base + 0x1000000, // +1MB

The test.bin is bare uart test-app we test ok in imx51 board, we change the entry as 0x61009000, correspond with Start_addr.

Maybe we make some mistakes, who can give some guidance and suggestions?

Looking forward to your reply.
