Configuring vxWorks with both a BSD and an END driver

Problem Description

1. To build a bootrom from which it is possible to boot from either a specific BSD 4.4 \"fei\" driver or \"elPCI\" END driver, and  

2. To attach a second BSD or END interface.

This procedure is specific to the x86 targets, but the principles can be applied to any BSP.

Problem Solution (1)
To configure a  bootrom and runtime image that supported both the BSD fei driver and elPci END driver, the following changes were made to the \"Network driver options\" section of config.h:

#define INCLUDE_BSD   /* Must be added for BSD44 support */
#define    INCLUDE_END
...

/* INCLUDE_FEI is normally defined by default
* Verify that it is defined.
*/

#define    INCLUDE_FEI /* include Intel Ether Express PRO100B PCI */
...

/* EL_3C90x_END was defined.  
* This card only as an END driver.
* All other network interfaces were undef\'ed.
*/

#define INCLUDE_EL_3C90X_END    /* 3com fast etherLink XL PCI */


/* Remove or comment the #ifdef INCLUDE_END
* Make sure COMM_TYPE is COMM_NETWORK
*/
/* #ifdef INCLUDE_END */

#   undef  WDB_COMM_TYPE
#   define WDB_COMM_TYPE    WDB_COMM_NETWORK  

/* Finally, comment out the following so the END driver
* is not used.  
* This is to demonstrate the target can boot with a
* BSD driver and that both BSD and END can co-exist.
*/
/*
#   ifdef INCLUDE_FEI
#    undef INCLUDE_FEI    
#    define INCLUDE_FEI_END    
#   endif
*/

No changes were made to configNet.h, although based on the specific BSD and configNet.h this might be necessary.


A project was built based on the BSD where the modified config.h lived. VxWorks was configured with a downloaded symbol table and shell, show routines and network debugging facilities.

Problem Solution (2)

The target was first booted using the BSD44 \"fei\" driver.

Next, the elPci interface is attached using the commands ipAttach, ifMaskSet and ifAddrSet, in this specific order:

-> ipAttach 0, \"elPci\"
value = 0 = 0x0
-> ifMaskSet \"elPci0\", 0xffffff00
value = 0 = 0x0
-> ifAddrSet \"elPci0\", \"192.192.192.192\"
value = 0 = 0x0

Again, ifShow displays both the \"fei\" and \"elPci\" interfaces.

Next, we\'ll demonstrate the target can boot with the same bootrom over the elPci END interface and the same vxWorks image can support an additional BSD interface as well.

This time, the additional interface is a BSD4.4 device, and usrNetIfAttach and usrNetIfConfig are used to attach the \"fei\" interface and assign an IP address and subnetmask.
