SD驱动开发问题：客户端驱动加载成功，但盘符显示不出来？？？

有哪位牛人做过SD驱动吗？帮忙分析一下，谢谢！
详细现象：
   1、 硬件平台是自己实验室研发的，OS为WINCE600；
   2、 总线驱动、主控制驱动都能成功加载
    ——SD命令发送也成功：
   CMD5-CMD0-CMD55+ACMD41-CMD0-CMD55+ACMD41-CMD2-CMD3-CMD9-CMD13-CMD7-CMD55+ACMD51-CMD55+ACMD42-CMD55+ACMD6。
   3、客户端驱动加载成功，并且，我感觉系统也识别到了SD卡，由如下两点可知：
   1>~_~_~_SDMemory: Idle Timeout Wakeup after 2000 MS //此行信息是idlethread线程中的信息，
   2>在内存管理器中，能看到有SD的内存空间，当然，此处也有一个问题，我的SD卡是1G的，而内存管理器中显示是512M的？？
   4、分区驱动（partition Driver）组件也加了；；；；

希望有牛人帮忙指点，谢谢！！

我参考的主要是S3C2440A的代码，另外，小部分是参考了S3C6410的，谢谢

目怜心

注册表设置呢？

这个是可以的，自己对照着看下吧，我也不懂

有人说是分区驱动的原因，不过，我加了分区。。。？

有没有相关的trace？打印出来看看
你在换换512M或者4G的sd卡分别试一下，把
trace贴出来

coffeewjf

有的，我整理一下，一会帖出来

还有其他的debug信息么？
1. 看起来你打印的信息挺多的，能不能把后面的信息也给打印出来？
2. 你的sd卡能够在pc上识别么？

游客

楼主找一个没有分区的小容量SD卡，做一次实验，看看测试结果如何，
如果能显示图标，就说明是分区驱动的问题

SD卡在PC上是好的。。。
打印信息确实比较多，没法全贴上来，所以，将前面那部分去掉了，
去掉的那部分打印信息主要是总线驱动、主控制驱动的，主要是发送如下一串命令：
CMD5-CMD0-CMD55+ACMD41-CMD0-CMD55+ACMD41-CMD2-CMD3-CMD9-CMD13-CMD7-CMD55+ACMD51-CMD55+ACMD42-CMD55+ACMD6。
据打印信息来看，命令是发送成功了。。。。

分区和fs的注册表：我都是用的默认的，即：自己没修改过，只在Catalog Itams View中将分区组件Partition Driver选上，用的是VS2005工具。。。
分区和fs的注册表：还需要在别的地方另外再添加或修改吗？请指点！

如下信息是开始加载客户端驱动的信息：
显示不了盘符会不会加载不完全，请帮我看看问题出在什么地方，致谢

LZ你抓到的这段信息是什么东西？是MBR？

看上去比较像DBR啊，可是最后不是0x55AA。

levenshiry

上面那些0x进度的数字吗？
我真没太注意是什么。。。

我只知道是发送ACMD51号命令时，会通过DMA传输一些数据，就是这些

盘符出不来，是不是和这个有关呢？

businiao0002007

好像应该是MBR，我在word中统计了一下，总共512B（字节），而SD的第0块大小也是512B（字节）。。。

这些数字该怎么去用？如何识别？

刚才说错了，是512组数据，而这些是十六进制的，所以，512*4=2K字节。。。SD的第0块大小也是2K（字节）。。。
