Hi Christian, Thank you so much!
Now it works. There was a problem with the file system (ram_fs) configuration in the run script. But it only works when i perform the file access inside the *main()* function of tz_vmm. it generates the following error when i try to access the file inside *_handle_hypervisor_call()* function after the normal world performs a secure method call (smc) to the secure world. Can you please tell me what is missing? * int -> tz_vmm ->vmm: unresolved pagefault at ip=700ac620 sp=e01fcfe8 core -> pager_ep: cannot submit unknown signal context.* thanks, On Tue, Oct 27, 2015 at 2:45 PM, Christian Helmuth < christian.helm...@genode-labs.com> wrote: > Hello Joseph, > > On Mon, Oct 26, 2015 at 03:28:40PM +0100, Joseph Lee wrote: > > please find attached patches for Genode 15.08. > > Your patches do not apply to Genode 15.08.
