hi： I try add vm in zynqmp, but when run rootserve crash. print See appendix for the log Function call stack create_objects for (int ut_index = 0; ut_index < spec->num_untyped; ut_index++) { .... CDL_Object *obj = &spec->objects[obj_id]; CDL_ObjectType capdl_obj_type = CDL_Obj_Type(obj); ----case crash } I fount when it access 0x440010 (the 42th of capdl_spec.objs, 0~41 objs access is OK) which is (CDL_Object)obj->type will case the crash, but I access the 42th obj->name ("frame_vm0_group_bin_0132" can be printed) is OK. [42] = { #ifdef CONFIG_DEBUG_BUILD .name = "frame_vm0_group_bin_0132", #endif .type = CDL_Frame, .size_bits = 21, .frame_extra = { .paddr = 0, }, },

what may be the problem ? mmu? Thank you very much.
