Undefined: class_interface_map

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
(
/* interface's device/descriptor/pipe bundle */
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_
DEBUG_LOG_TRACE("usb_host_map_class_intf");
#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

Hi amleng,

examples work out of box, without any need to include or define anything. I builded this example in MQX 3.8 and none errors were shown.

Regards,

When I create this example application using CW 10.1 project wizard I got this error and some other link errors. Bit if I import the project to workspace the code runs without any error.

I added usb_classes.c to project and #define USBCLASS_INC_MASS 1 in usb_classes.h then it works well.
