关于在IDE Primary Slave 启动VXWROKS的问题
我的CF卡接在IDE Primary Slave上，即主通道的从盘，至于如何设置ATA启动请参看我的另一篇发在论坛的文章《tonado2.2.1下X86的CF卡启动及WINDML3.0配置过程》：
这样定义启动参数：
#define DEFAULT_BOOT_LINE \
"ata=0,1(0,1)host:/ata0/vxworks h=192.168.0.37 e=192.168.0.17 g=192.168.0.2 pw=1 f=0x08 u=tr tn=tr o=rtl0"
#define DOSFS_NAMES_ATA_PRIMARY_SL****E "/ata0"



#define SYS_WARM_ATA_CTRL 0 /* controller 0 */
#define SYS_WARM_ATA_DRIVE 1 /* 0 = c:, 1 = d: */
把这参数改对：
/* controller zero device one */



#define ATA_CTRL0_DRV1_CYL (980) /* ATA 0, device 1 cylinders */
#define ATA_CTRL0_DRV1_HDS (8) /* ATA 0, device 1 heads */
#define ATA_CTRL0_DRV1_SPT (32) /* ATA 0, device 1 sectors per track */
#define ATA_CTRL0_DRV1_BPS (512) /* ATA 0, device 1 bytes per sector */
#define ATA_CTRL0_DRV1_WPC (0x00) /* ATA 0, device 1 write pre-compensation */



#define ATA0_NUM_DRIVES (2) /* ATA 0 number drives present */
另外要注意一下NVRAM的问题！
在sysNvRam.c里的
static void sysNvRam_mount()
{
/* int ctrl = 0 这是主通道的要是换了从通道就不灵了*/
int ctrl = SYS_WARM_ATA_CTRL;/* I add*/
u_char * pVolDesc;



#if defined(INCLUDE_ATA) && (SYS_WARM_TYPE == SYS_WARM_ATA)
IMPORT ATA_RESOURCE ataResources[];
ATA_RESOURCE *pAtaResource
= &ataResources[ctrl];
#endif
/* ctrl = 0 这是主通道的要是还了从通道就不灵了*/
ctrl = SYS_WARM_ATA_CTRL; /*I add*/


/* if BOOTROM_DIR has already been mounted do not try remounting it */


if(NULL == dosFsVolDescGet(BOOTROM_DIR, &pVolDesc))
{
dosFsInit (NUM_DOSFS_FILES);
#if defined(INCLUDE_FD) && (SYS_WARM_TYPE == SYS_WARM_FD)
if (fdDrv (FD_INT_VEC, FD_INT_LVL) != OK)
{
return;
}


if(usrFdConfig(ctrl, 0, BOOTROM_DIR) != OK)
{
logMsg("%s: usrFdConfig failed\n", (int)__FUNCTION__,2,3,4,5,6);
return;
}
#endif
#if defined(INCLUDE_ATA) && (SYS_WARM_TYPE == SYS_WARM_ATA)
if (ataDrv
(ctrl, pAtaResource->drives, pAtaResource->intVector,
pAtaResource->intLevel, pAtaResource->configType,
pAtaResource->semTimeout, pAtaResource->wdgTimeout) == ERROR)
{
return;
}
/* if(usrAtaConfig(ctrl,0,BOOTROM_DIR) != OK) 这是主盘的，从盘就不灵*/
if(usrAtaConfig(ctrl,SYS_WARM_ATA_DRIVE,BOOTROM_DIR) != OK)/*I mod 让它跟CONFIG里的一起变*/
{
logMsg("%s: usrAtaConfig failed\n", (int)__FUNCTION__,2,3,4,5,6);
return;
}
#endif
#if defined(INCLUDE_TFFS) && (SYS_WARM_TYPE == SYS_WARM_TFFS)
if (tffsDrv () != OK)
{
return;
}


if(usrTffsConfig(ctrl,0,BOOTROM_DIR) != OK)
{
logMsg("%s: usrTffsConfig failed\n", (int)__FUNCTION__,2,3,4,5,6);
return;
}
#endif
}
}
