成功在skyeye 上实现U-Boot 的Nand命令并从Nand中启动Linux

内核配置是按照LZ的“http://blog.csdn.net/zblue78/archive/2008/02/20/2109827.aspx”中配置的

恳请大侠帮忙啊！！！

这个试过了吗？

我按lz说的方法去作了，可是在没有添加nand部分时执行的还好，即第7步之前正常。
但做到第10步的时候就不行了呢，
结果是

到这里就进行不下去了。这是为什么阿 ，其他的和你做的一样，SKYEYE。CONF也是一样的。
这样执行也不行

我在想是不是地址有问题。lz觉得我这边有什么不对的阿？

但做到第10步的时候就不行了呢，
结果是
:~/arm/rom3$ ls
nand.dump  skyeye.conf  skyeye.conf~  u-boot  u-b ...

用skyeye 提供的mknandflashdump程序将 我们的u-boot.bin文件镜像到nand.dump 文件中

mknandflashdump u-boot.bin nand.dump 0

没有做这个?

Canbus

请问楼主是怎么用skyeye就跟踪代码的。给个详细点步骤好吗？谢谢！！

liudows

lz的conf如下，有几点不懂想请教：

# physical memory
mem_bank: map=M, type=RW, addr=0x00000000, size=0x00800000,
file=./u-boot.bin ,boot=yes
请问这里指定的是nand flash吗?
如果是nor flash，怎么指定是从nand flash启动的呢？
如果是nand flash的话，2410中nand flash实际上不是连接到memory bank上的，为什么要这样指定？


我想仿照您的方法在skyeye for 2410中启动vivi，但是没有成功，故有以上疑惑。望指教，谢谢！

想s3c2410这样的芯片之所以可以在NAND上启动，是由于s3c2410有一个叫做stepping stone的内置SRAM，将loader代码烧在NAND上，加电后，该芯片可以自动将NAND的起始4k的内容拷贝到SRAM里，然后在RAM里执行。

deniel1212

修改 command/cmd_nand.c
中的NanD_ReadBuf函数
注释掉NanD_Command (nand, NAND_CMD_READ0);这一行
俺的是u-boot1.2.0竟然没有这个函数，自己弄了好久，不知该怎么改。
