我用qq2440提供的3.4.1居然能编译过去了，，不知道怎么回事，，另外还有问题请教版主，，就是我改好了支持128M NAND的uboot，在mini2440开发板上就能跑起来，，而在我的te2440开发板上却没有任何输出信息，，问题可能出现在哪里呢？

你能不能一次把问题说清楚？
你是怎么让uboot支持128M NAND的？你的uboot现在是只支持从128M NAND启动还是兼容从64M NAND启动？TE2440是从64M NAND Flash启动？

目前，我这有两块开发板，mini2440,和te2440,我参考的是qq2440中的光盘资料：vivi 源码包，和uboot源码包，它们都是支持64M nand ,而我的两块板子都是128M,,前段时间我改了vivi,使他在我的板子跑起来了，，现在我在改uboot,我修改的方法和vivi中一样，，但是现在uboot在mini2440能跑起来，但是在te2440却跑步起来。。可能是哪里的问题呢？和时钟有关吗？

可能和TE2440 NAND启动时GPG13,14,15这三根PIN的电平有关，128M NAND Flash和64M的配置是不一样的，具体信息看S3C2440A CPU用户手册“NAND Flash Controller”一章中的描述。

S3C24X0_GPIO这个结构体定义已经更改过了，不再包含GPACON这样的成员，根据代码中S3C24X0_GPIO的定义修改你的源代码

版主，可以详细讲解一下吗？我在s3c24x0.h这个文件里面看到typedef struct {S3C24X0_REG32 GPACON} S3C24X0_GPIO这样定义的，但不知道如何修改。编译u-boot-2008.10也会出现这种情况。

我已经在http://www.aiothome.com/bbs/read.php?tid-3407.html里回复了，这个帖子没有必要再讨论下去
