微软默认的nand驱动，它使用nand每个page后面得sparepage来保存物理page和逻辑page的映射关系。

WINCE5.0 + 2440 启动部分

我按照mini2240的eboot先进行分区。。前面25个block是NBOOT.eboot.TOc,后面就是分区MBR,我将根据NK的大小分出那么大的BINFS的分区，后面的都是分成FAT的分区。从打印的信息来看我的分区是正确的，但是我没有去读分区表的信息来确认。下面我给出我的debug的打印信息

从打印信息上看这几句话似乎很给了我信息
0x8fee5000: FLASHDRV.DLL:L2P_GetPhysicalSectorAddr() - Secondary table doesn't exist for logical sector
1.这句话说Secondary table是什么意思？
0x8fee5000: FLASHDRV.DLL:ReadFromMedia() - Unable to determine physical sector address for logical sector 0x0000ea40
2.ReadFromMedia这个函数是FAL里面的函数吧，CE5里面看不到，这句话说不能把logic sector转换成真实的物理地址。难道是我的分区表中的逻辑起始地址不正确？？？但是从分区打印信息上看是正确的啊。。。分明在加载完分区驱动后能很好的读出两个part中的信息。还是正确的。
3.从我从这句话猜测0x8fee5000: FATFS!InitVolume: Cluster Size (Sectors): 0肯定是BINFS没有mount上去的原因。

[b]【Walle】你用的是微软默认的nand驱动，它使用nand每个page后面得sparepage来保存物理page和逻辑page的映射关系。如果你的eboot（或其他bootloader）没有在烧image的时候写spare page的这部分映射数据，wince在启动的时候需要读取binfs部分数据的时候调用nand驱动去试图得到逻辑扇区0所对应的物理page的时候，会得不到映射表而失败。[/b]

[b]【walle】FAL在ce5是没有opensource的，你有兴趣可以看ce6的private，有source哦！[/b]

[b]【walle】cluster size之类的数据保存在DBR扇区里面，根据上面的分析，你的nand驱动无法知道逻辑扇区的数据藏在哪里，所以不可能得到。[/b]

你所说的sparepage 里面的物理页和逻辑页的映射关系是不是通过标记坏块来实现的。如果不是，想听你解释下映射是怎么做的，因为sparepage里面就有一些标记位和ecc.如果是的话。你的意思是我在bootloader中对块的标记错了。。。。
非常谢谢你的回答，也希望你能继续关注。。

eboot在写image到nand的时候，可以在写main area的data的同时，把逻辑page写入到该page的spare area。
告诉你个方法，你可以改nand的驱动，让它故意返回顺序的逻辑page号（如果没有坏块，物理page往往和逻辑page是线性对应，只是开始号码不同，比如物理page 0x1000对应逻辑page 0x0，那么相应的0x2000 = 0x1000）

unsway 发表于 2009-9-23 14:05

spare area不就那么几个字节吗？你的意思就是直接去读spare area的那些字节。。然后再来分析。。。最近忙着弄摄像头，，已经很长时间没有关注过这个事情了

Walle 发表于 2009-9-25 15:33

每个物理page里面的spare区域保存一个dword的逻辑page号码就可以了。
