VxWorks 5.5 BSP Developer’s Guide ... include $(TGT_DIR)/h/make/defs.bsp ... include $(TGT_DIR)/h/make/rules.bsp ... The defs.bsp and rules.bsp files now include any other files necessary to build your BSP. To modify your BSP, simply comment out the unnecessary includes in your makefile. In addition, a makefile conversion tool, bspCnvtT2_2, has been provided in the installDir/host/$(WIND_HOST_TYPE)/bin directory. You can invoke bspCnvtT2_2 with the following syntax: % bspCnvtT2_2 bspName1 bspName2 ... bspCnvtT2_2 converts your makefile by performing the following actions: ■ ■ ■ Saving your old makefile to a file named Makefile.old in your BSP directory. Commenting out the unnecessary includes. Warning you about the use of any hex build flags. (See Hex Utilities and objcopy, p.212.) Hex Utilities and objcopy The use of Wind River-provided hex and binary utilities, such as aoutToBinDec or coffHexArm, has been deprecated in favor of the GNU utility objcopy. See the GNU Toolkit User’s Guide chapter on binary utilities for details. It is recommended that you modify your BSP build settings as necessary to use objcopy. New Default Value of WDB_COMM_TYPE The WDB_COMM_TYPE default value has been changed from WDB_COMM_NETWORK to WDB_COMM_END. If you plan to use a different communication mode, define it explicitly in config.h. For example, if by default your BSP sets up WDB communication on a serial line, you should include the following line in config.h: ... /* make sure this appears after inclusion of configAll.h */ #define WDB_COMM_TYPE WDB_COMM_SERIAL ... 212
B Upgrading a BSP for Tornado 2.2 Changes in the Shared Memory Subsystem A BSP for VxWorks 5.5 requires several modest changes to config.h and possibly to sysLib.c in order to support the shared memory network and the optional component VxMP. In past releases of VxWorks, you could ensure that the shared memory components were included simply by verifying the inclusion of the shared memory backplane network. But in VxWorks 5.5, VxMP can be configured without support for the shared memory network. A new component with the inclusion macro INCLUDE_SM_COMMON has been added to VxWorks 5.5. Use this macro to test for shared memory support. The majority of BSPs that support shared memory use conditional compilation statements such as the following: #ifdef INCLUDE_SM_NET /* shared memory-specific code */ #endif For VxWorks 5.5, these statements must be updated to test for INCLUDE_SM_COMMON: B #ifdef INCLUDE_SM_COMMON /* shared memory-specific code */ #endif When you modify sysLib.c, follow the simple rule of replacing all instances of INCLUDE_SM_NET with INCLUDE_SM_COMMON. With a few exceptions, you can use the same rule in changing config.h. A test for INCLUDE_SM_NET is still valid in network-related statements, but is not valid as a test for the common shared memory parameters: SM_ANCHOR_ADRS SM_ANCHOR_OFFSET SM_CPUS_MAX SM_INT_ARG1 SM_INT_ARG2 SM_INT_ARG3 SM_INT_TYPE SM_MASTER SM_MAX_WAIT SM_MEM_ADRS SM_MEM_SIZE SM_OBJ_MEM_SIZE SM_OFF_BOARD SM_TAS_TYPE These shared memory parameters do not require conditional compilation and can be left defined at all times. (Note that some are defined by default in configAll.h and must be undefined before being redefined in config.h.) The definition of INCLUDE_SM_NET in config.h may also bring in components that have changed in VxWorks 5.5, such as INCLUDE_NET_SHOW and INCLUDE_BSD. These components are no longer needed; the smNetShow( ) routine is now in a separate component, called INCLUDE_SM_NET_SHOW, and proper BSD or other network configuration is contained in other files. 213
