]]>kernel 2.6.23.9 UL?S3C2412q_http://www.shnenglu.com/agaric/archive/2008/01/28/42076.html菌子菌子Mon, 28 Jan 2008 15:30:00 GMThttp://www.shnenglu.com/agaric/archive/2008/01/28/42076.htmlhttp://www.shnenglu.com/agaric/comments/42076.htmlhttp://www.shnenglu.com/agaric/archive/2008/01/28/42076.html#Feedback0http://www.shnenglu.com/agaric/comments/commentRss/42076.htmlhttp://www.shnenglu.com/agaric/services/trackbacks/42076.html 

我用的不是SMDK2412的开发板Q而是公司已经?412的机器，原来用的是自q一个OSQ现在打在他上面运行linux.

~译2.6的内核，需要比较新的gcc, 我暂时能扑ֈ的新版arm-linux-gcc也就?.4.1。，之前用arm-none-linux-eabi-gcc 4.1~出来的zImage好大Q基本不能用。对于开发工具和内核版本Q我觉得q是新好Q稳定版Q，否则可能会遇C些稀奇古怪的问题?/p>

1.修改Boot

使用公司原有的Boot, 在Boot启动Kernel的时候，加入的参数设定，然后用公怸用的usb更新工具烧录kernel到flash中，启动机器以后昄了一堆ؕ码，在启动参?console=ttySAC0后面加上?115200Q设定L特率以后一切OK.

2.MTD分区Q修Ҏ件common-smdk.c Q?修改其中的MTD讑֤的分区?/p>

新的kernel里面已经有了默认分区表，我们只要Ҏ我们需要来做部分修改就可以Q我的nand?12MBQ?我目前只是将前面?M分给boot,kernel, 紧接下来?M分给rootfsQ打暂时加载一?单的cramfs。其他的nand都还没有用?/p>

3.取消NAND驱动中的ECCL验，以及坏块监测部分, 因ؓNAND操作部分Qboot和kernel有一些不同?/p>

重启以后Qmount root分区p|Q还打出了I/O 错误?关闭了ECC校验Q修改了pc工具的烧录地址以后Qok. q都是因为我们的烧录工具使用的地址表示Ҏ和ecc的方式有一些不同?/p>

4.烧录 root 文gpȝ?/p>

拿了一个在kernel2.4 2440 上用q得cramfs直接来用Q提C找不到dev/consoleQ?上网查了一遍，应该是因为现在新版的kernelL了devfs的缘故，Z先快速的有一个可执行环境Q所以在|上找了一个现成的Q已l自己徏立好节点的cramfsQ里面的busybox版本也比较新?

 

开行，ȝ见到了亲qshell.
