在成功移植了天嵌教程的2.6.25和2.6.30.4内核后。我又开始自己移植了2.6.35.不过遇到了以下问题,请版主解决一下。
环境:VM+Fedora10
交叉环境:4.3.3
内核版本:2.6.35
硬件:TQ2440 256M NANDflash
按照手册移植时,当移植到了nandflash驱动时,我先把内核镜像烧到flash中,(此时还没有移植文件系统)。我直接烧写zImage,串口打印信息:
RECEIVED FILE SIZE: 2037710 (994KB/S, 2S)
NOW, Booting Linux......
Uncompressing Linux...
uncompression error
-- System resetting
后来我又编译了make uImage。我将uImage烧写到flash中,用nand read 0x32000000 0x200000 0x300000;bootm 0x32000000;内核又可以正常启动,串口打印如下:
EmbedSky> bootm 0x32000000

于是,我又将make uImage同时生成的zImage烧到flash中,用nand read 0x32000000 0x200000 0x300000;go 0x32000000
串口打印如下信息:

奇怪了啊,怎么会出现这种事情呢,同样的内核只是格式不同,怎么会出现这么多种不同的状况呢?天嵌的uboot是支持zImage格式的啊。。。。。。。。。。 |
