VxWorks 5.5 BSP Developer’s Guide driver would not reside in the target/src/drv directory but in a BSP-specific directory (from which the BSP’s sysLib.c can include the driver when needed). F.2 Serial Drivers Generic serial drivers reside in the directory target/src/drv/serial. Included in this directory is templateSerial.c and its corresponding header file, templateSerial.h. These files contain very detailed information on the design and construction of a typical serial driver. When writing a serial driver, base the driver on this template, then modify the BSP’s sysLib.c or sysSerial.c files to include the driver as needed. NOTE: Serial drivers are provided for backward compatibility with VxWorks 5.2 and earlier. All Tornado-era BSPs should instead use the SIO drivers. To manage information about a serial device, sysLib.c uses a device descriptor. This device descriptor also encapsulates board-specific information. For example, it typically includes the frequency of the clock and the addresses of the registers, although the details are dictated by the device in question. In sysLib.c, the serial device descriptor is declared outside the function definitions as: TY_CO_DEV tyCoDv [NUM_TTY]; /* structure for serial ports */ This array is initialized at run-time in sysHwInit( ). The TY_CO_DEV structure is defined in the device header file (for example, target/h/drv/serial/z8530.h). The following members of the TY_CO_DEV structure are common to all serial drivers: tyDev Required by tyLib, the VxWorks tty driver support library. created A flag that must be initialized to FALSE in sysHwInit( ). numChannels Used for parameter checking. The following macros must be defined for all BSPs: NUM_TTY Defines the number of serial channels supported. In configAll.h, the default defined as 2. To override the default, first undefine then define NUM_TTY in config.h. If there are no serial channels, define NUM_TTY as NONE. 248
F Generic Drivers CONSOLE_TTY This macro defines the channel number of the console. In configAll.h, the default defined as 0. To override the default, first undefine then define CONSOLE_TTY in config.h. F.3 Multi-Mode Serial (SIO) Drivers The generic multi-mode serial drivers reside in the directory target/src/drv/sio. These drivers are called SIO drivers to distinguish them from the older serial drivers that only have a single interrupt mode of operation. SIO drivers provide an interface for setting hardware options, such as the number of stop bits, data bits, parity, and so on. In addition, these drivers provide an interface for polled communication that can provide external mode debugging (such as ROM-monitor style debugging) over a serial line. Currently only asynchronous-mode SIO drivers are supported. Every SIO device is controlled by an SIO_CHAN structure. This structure contains a single member, a pointer to an SIO_DRV_FUNCS structure. These structures are defined in target/h/sioLib.h as: typedef struct sio_chan /* a serial channel */ { SIO_DRV_FUNCS * pDrvFuncs; /* device data */ } SIO_CHAN; F typedef struct sio_drv_funcs SIO_DRV_FUNCS; struct sio_drv_funcs /* driver functions */ { int (*ioctl) ( SIO_CHAN * pSioChan, int cmd, void * arg ); int (*txStartup) ( SIO_CHAN * ); pSioChan int (*callbackInstall) ( 249
