VxWorks 5.5 BSP Developer’s Guide To set appropriate values for these constants, consider the following: END_LOAD_FUNC Specify the name of your driver’s endLoad( ) entry point. For example, if your driver’s endLoad( ) entry point is ln7990EndLoad( ), you would edit config.h to include the line: #define END_LOAD_FUNC ln7990EndLoad END_LOAD_STRING Specify the initialization string passed into muxDevLoad( ) as the initString parameter. You must also edit the definition of endTbl (a table in configNet.h that specifies the ENDs included in the image) to include the following: END_TBL_ENTRY endTbl { { 0, LOAD_FUNC_0, LOAD_STRING_0, BSP_0, FALSE}, { 1, LOAD_FUNC_1, LOAD_STRING_1, BSP_1, FALSE}, { 0, END_TBL_END, 0, NULL}, }; The first number in each table entry specifies the unit number for the device. The first entry in the example above specifies a unit number of 0. Thus, the device it loads is deviceName0. The FALSE at the end of each entry indicates that the entry has not been processed. After the system successfully loads a driver, it changes this value to TRUE in the run-time version of this table. To prevent the system from automatically loading your driver, set this value to TRUE. Finally, you must edit your BSP’s config.h file to define INCLUDE_END. This tells the build process to include the END/MUX interface. A this point, you are ready to rebuild VxWorks to include your new drivers. When you boot this rebuilt image, it calls muxDevLoad( ) for each device specified in the table in the order listed. 1 1. For a description of the parameters to muxDevLoad( ), see the appropriate reference entry. 222
D VxWorks Boot Sequence Table D-1 documents the sequence of initialization for a ROMmed VxWorks or boot ROM image. This sequence only applies to images built from the traditional command line. NOTE: You can expect, in a future release, that this old initialization sequence will be obsoleted in favor of project and component initialization groups. Images built from the project facility follow a different but similar initialization sequence based on initGroups described in the component description files. See E.3 Project Initialization Order, p.238 for the project component initialization order. Table D-1 VxWorks Boot Sequence Functions Activity File 1. romInit( ) (a) disable interrupts romInit.s (b) (c) save boot type (cold/warm) enable DRAM and DRAM refresh (hardware independent) (d) branch to romStart( ) (position independent code) 2. romStart( ) (a) copy text (and data) segment from ROM to RAM bootInit.c (b) (c) clear memory (if necessary) decompress (if necessary) 223
