其中出现的错误为：

WARNING: Failed to create 0 bytes of disk cache ATA disk /vxboot/ configured wit hout cache 0x2d93dc (tBoot): cbioWrapBlkDev: BLK_DEV pointer 0x002ffee8 appears invalid. 0x2d93dc (tBoot): cbioWrapBlkDev: BLK_DEV pointer 0x00000000 appears invalid. Error creating partition manager: 850001 0x2d93dcAttached TCP/I (P interface to tBootrtl): sysNvRam_mount0: usrAtaConfig failed 我的具体做法：

1、将config.h里的SYS_WARM_ATA_CTRL修改为1。

2、对config.h里的CF卡参数进行设置：

#define ATA_CTRL1_DRV0_CYL (980) /* ATA 1, device 0 cylinders */ #define ATA_CTRL1_DRV0_HDS (16) /* ATA 1, device 0 heads */ #define ATA_CTRL1_DRV0_SPT (32) /* ATA 1, device 0 sectors per track */ #define ATA_CTRL1_DRV0_BPS (512) /* ATA 1, device 0 bytes per sector */ #define ATA_CTRL1_DRV0_WPC (0xff) /* ATA 1, device 0 write pre-compensation */

3、将config.h里的ATA1_CTRL_TYPE修改为IDE_LOCAL

4、将config.h里的ATA1_INT_LVL修改为0x0f

说明：我的CF卡是Second_Primary。利用ataLoad( 1, 0, "\ata0\VxWorks" )加载CF卡上的VxWorks文件。这些都成功了，但就是出现上面的错误！我在网上看了好多同志跟我的情况一样，哪位做过的能帮帮我们吗？？？
