Can you please tell me what is missing? The actual hypervisor call is handled by a thread beside the main thread. In tz_vmm.cc:52 the stack size of the thread is defined to 8K which is too small to execute legacy code like the libc. Please change to line to something like class Vmm::Vmm : public Thread<0x8000> and retry.
