Hello all,
I try to build and run a "mass storage device" example in :
MQX 3.8\usb\host\examples\msd\msd_commands
I got error " Undefined: class_interface_map" in host_common.c in the following part:
/*FUNCTION*----------------------------------------------------------------
*
* Function Name : usb_host_map_class_intf
* Returned Value : pointer to matching class map item, or NULL
* Comments :
* Map interface class etc. to a class driver table item.
* It is presumed that this function is called with USB interrupts disabled
*
*END*--------------------------------------------------------------------*/
static CLASS_MAP_PTR usb_host_map_class_intf
(

PIPE_BUNDLE_STRUCT_PTR pbs_ptr

{ /* Body */
CLASS_MAP_PTR map_ptr;
INTERFACE_DESCRIPTOR_PTR intf_desc;
uint_32 intf_class, map_class;
#ifdef _HOST_DEBUG_

#endif
intf_desc = (INTERFACE_DESCRIPTOR_PTR)pbs_ptr->intf_handle;
for (map_ptr = &class_interface_map[0]; ; map_ptr++) {
if (map_ptr->class_init == NULL) {
map_ptr = NULL;
break;
} /* EndIf */
intf_class = usb_hostdev_mask_class_etc(&intf_desc->bInterfaceClass,
&map_ptr->class_code_mask);
map_class = usb_hostdev_mask_class_etc(&map_ptr->class_code,
&map_ptr->class_code_mask);
if (intf_class != 0)
{
if (intf_class == map_class)
{
break;
}
}
} /* EndFor */
#ifdef _HOST_DEBUG_
DEBUG_LOG_TRACE("usb_host_map_class_intf SUCCESSFUL");
#endif
return map_ptr;
} /* EndBody */
I found this struc in usb_host_msd_bo.h but i am not sure how can I define this structure in host_common.c module.
typedef struct _Usb_Mass_Intf_Struct {
GENERAL_CLASS G; // This is general class containing following
_usb_pipe_handle CONTROL_PIPE; /* control pipe handle*/
_usb_pipe_handle BULK_IN_PIPE; /* Bulk in pipe handle*/
_usb_pipe_handle BULK_OUT_PIPE; /* Bulk out pipe handle*/
MASS_QUEUE_STRUCT QUEUE; /* structure that queues requests*/
uint_8 INTERFACE_NUM; /* interface number*/
uint_8 ALTERNATE_SETTING; /* Alternate setting*/
CLASS_CALL_STRUCT_PTR APP; /* Store app handle, can help finding if lost */
} USB_MASS_CLASS_INTF_STRUCT, _PTR_ USB_MASS_CLASS_INTF_STRUCT_PTR;
I use twrK60 and CW 10.1
