还有不明白，TWRPH0和TWRPH1的取值范围应该是0-7啊，怎么会 =8？

回cole3：

不对的是  Tacls=4, 39ns Twrph0=8 79ns, Twrph1=8 79ns，
对的是 Tacls=3, 29ns Twrph0=7 69ns, Twrph1=3 29ns。
没有8啊 。请看清楚。

但我在想啊，时间更长应该更好才是啊 ，怎么反而不对呢，难道因为 ，譬如Twrph0 设成8 ，是1000，但Twrph0 只能 是3位的，变成了0了？

首先如果认为书是对的，就不会来这指出错误了；对于高手来说手册当然没啥用，但对于我们这种自学，而且大多是一个人自学，必须有一个切入点，这种有具体实例的手册之类的资料，就提供我们这类菜鸟一个切入点。如果没有看了N久书，理解那些晦涩的原理，到头来还是蒙蒙懂懂，不知如何下手。
手册有点小错误从另个角度来说其实是一个好处，因为出现错误，就会去找解决方法，从而进一步理解为什么会出错，为什么要这样做，而解决方法就需要你们这些高手来提供，所以希望各位大神慷慨赐教。

我安书里面做的就不行呀，
就是到添加下面代码这步
编译总是出现后面的问题呀。

回13楼：
把下面几个头文件加上：

#include <linux/mtd/mtd.h>
#include <linux/mtd/nand.h>
#include <linux/mtd/nand_ecc.h>
#include <linux/mtd/partitions.h>
#include <plat/nand.h>

只需要把<linux/mtd/nand.h>和<plat/nand.h>加上就好了   另外就是s3c_device_nand.dev.platform_data=&mini2440_nand_info加在那个初始化函数里就行了  否则回警告但是可以编译通过，结果就是nand没有被内核认到   哈哈   也折腾我几个小时啊

谢谢，我正为这事头疼，谢谢高手们。

这些手册没有经过验证，就发出来了，对于想自学的人是一种不负责任的态度。

论坛上的教程有些是根本行不通，希望高手们能替初学者们舍身处地的想一下，同样产交流，但也不能给了别人希望，又让人绝望。好的、有用的教程才能流向社会，广为传播！

再次照着手册移植，遇到这个问题，解决了  哈哈！！！
“只需在mach-mini2440.c的初始化函数mini2440_machine_init(void)里加入s3c_nand_set_platdata(&mini2440_nand_info);即可。”
