下载*.yaffs文件的问题解决了，又来了新问题。
|
首先，对*.yaffs文件下载问题进行简单回顾。
使用ls -la命令查看tftp目录下文件的属性：
[root@localhost tftp]# ls -la
总计 14192
drwxr-xr-x 2 root root 4096 03-01 19:33 .
drwxr-xr-x 11 root root 4096 02-26 21:19 ..
-rw------- 1 root root 12818784 02-26 21:10 fsmdev.yaffs
-rwxr-xr-x 1 root root 133488 03-01 19:33 u-boot.bin
-rw-r--r-- 1 root root 1530340 02-26 21:19 uImage
的确是fsmdev.yaffs文件的属性和其它如u-boot.bin文件的属性是不一样的。因此执行如下命令，方可改变该文件属性。
[root@localhost tftp]# chmod 777 fsmdev.yaffs
这样就更改了该文件的属性，即解决了载入yaffs文件系统文件的问题。
下面遇到了写入yaffs文件系统文件的问题。
如下：
PCY2410 # nand write.yaffs 32000000 300000 2800000
NAND write: device 0 offset 0x300000, size 0x2800000
Input block length is not page aligned
Data did not fit into device, due to bad blocks
41943040 bytes written: ERROR
后来使用如下命令可以写入文件。
PCY2410 # nand write.yaffs2 32000000 300000 2800000
NAND write: device 0 offset 0x300000, size 0x2800000
41943040 bytes written: OK
但写入和不写入，内核启动提示的错误信息是一样的。

这就是在昨晚遇到的问题。
