Upgrading a BSP for the
VxWorks Network Stack
Adding your driver to the target VxWorks system is much like adding any other
application. The first step is to compile and include the driver code in the VxWorks
image. For a description of the general procedures, see the Tornado User’s Guide:
Projects, which tells you how to compile source code to produce target-suitable
object code.
Including most software modules in the VxWorks image is usually just a matter of
setting a few #define statements. Adding a network interface driver does not
require much more. However, because VxWorks allows you to create more than
one network device, you must also set up a table that groups the #define
statements into device-specific groups. This table is defined in
target/src/config/BSP/configNet.h, where BSP is the name of your board support
package, such as mv162 and pc486.
For example, if you wanted VxWorks to create two network devices, one that
supported buffer loaning and one that did not, you would first edit configNet.h to
include the following statements:
/* Parameters for loading the driver supporting buffer loaning. */
#define LOAD_FUNC_0 ln7990EndLoad
#define LOAD_STRING_0 "0xfffffe0:0xffffffe2:0:1:1"
#define BSP_0 NULL
/* Parameters for loading the driver NOT supporting buffer loaning. */
#define LOAD_FUNC_1 LOAD_FUNC_0
#define LOAD_STRING_1 "0xffffee0:0xfffffee2:4:1:1"
#define BSP_1 NULL
