Hello Stefan

Thanks for your reply. I tried at 80008000 address as well.

abhishek@...514...:~$ file linux
linux: u-boot legacy uImage, Linux-2.6.35.3-01384-g9533414-di, Linux/ARM, OS Kernel Image (Not compressed), 2933872 bytes, Wed May 31 15:52:08 2017, Load Address: 0x80008000, Entry Point: 0x80008000, Header CRC: 0x83CD7B97, Data CRC: 0x914C7C24

I tried to print from `start` function in "os/src/server/tz_vmm/include/vm_base.h" file.

                void start()
                {
                        Genode::memset((void*)_state, 0, sizeof(Genode::Vm_state));
                        _load_kernel();
                        _load_kernel_surroundings();
                        _state->cpsr = 0x93; /* SVC mode and IRQs disabled */
                        _state->r0   = 0;
                        _state->r1   = _mach_type;
                        _state->r2   = _ram.base() + _board_info_offset();
                }

_load_kernel() and other statements are working perfectly fine, I tried printing after each line using PINF. I think that means kernel is loading fine, though I'm not sure. What might be going wrong here?

Thanks

Abhishek

You are trying to relocate the Linux kernel within the memory portion
that is used by the secure world (Genode). The secure RAM is from
0x70000000 to 0x7fffffff. Please follow these instructions to build the
guest kernel on your own, like referenced within the tz_vmm run-script:
