哪里的哪个文件？按着这个添加就可以了吗？

没看到你分的区，看看是否分区有误，还有支持的配置！ 你是用nfs 還是flash
你板子的bootargs 有設對嗎? TQ2440的板子怎么看分区信息啊？bootargs怎么设置才对啊？这个不知道怎么改在哪儿看啊？以前板子上带的是wince 是学姐烧过的我只用擦出了一遍 ~悟`~念~ 发表于 2012-5-10 23:46 static/image/common/back.gif

如果需要改分区，分区完成之后要改内核参数吗？改哪些在哪里改？我想直接烧写光盘里带的U_BOOT
请详细告知万分感谢！:D ~悟`~念~ 发表于 2012-5-10 23:46 static/image/common/back.gif

如图，我的意思是没有看到你的分区信息，看一下是否是你的分区错误，或者是配置错误，配置除了改内核就是make menuconfig里面的配置！这个需要细心，看你的启动信息，yaffs2文件系统也是没有移植成功，个人分析：因为nand flash分区那里有误，所以导致后面的移植失败！也不知道你做的是那个的移植，也没有说清楚，所以我只能说这些。至于配置的问题，建议看手册，手册上我个人觉得是很详细的，除了那些失效链接下载不了和串行问题，移植不成功就是个人不细心造成的！

直接烧写光盘里的uboot很简单，用USB一键下载或者用jtag都可以，这个手册的用法里讲的很清楚！ 本帖最后由 bluesnowbird 于 2012-5-11 10:34 编辑

我也试过用光盘里带的uboot直接烧写 并且烧写里面的linux 文件系统
就是按照光盘里说的移植啊可是总也不成功。。。
有时候烧写玩U-boot 或者烧写玩linux 内核或文件系统之后板子总会莫名其妙自己重新启动
或者烧写过程中自己启动。。。 不知道怎么回事
然后就提示bad crc or nandflash具体我也不清楚怎么了
自己编译了u-boot linux内核然后就成了现在这样了
我用的是usb转公口串口的线然后连接一个两头都是母口的串口线在连接上板子
usb下载线下载
在我选择9 格式化 1 ynandflash后有时候也会自动重启，有时是格式化的过程中就重启了。。
