6467文件系统制作与烧写

1、主要流程请参考TI官方说明

http://processors.wiki.ti.com/index.php/MTD_Utilities

2、利用mkfs.jffs2工具制作文件系统

mkfs.jffs2-n -r /mnt/loop/ -e 128 -o /tftpboot/rootfs.jffs2

mkfs.jffs2可以在直接下载安装：

apt-getinstall mtd-utils

也可以参考官方文档下载自己编译。

3、重新配置uboot参数，禁掉启动（noinitrd）
setenvbootargs mem=76M console=ttyS0,115200n8 root=/dev/mtdblock3 rw noinitrdrootfstype=jffs2

注意保存。

4、烧写文件系统

tftp 0x82000000 /tftpboot/rootfs.jffs2

nand erase 0x560000 0x7AA0000 //128M全部擦写干净，减少jffs2自检时间

nandwrite.jffs2 0x82000000 0x560000 0x1600000 //32M为文件系统实际大小

5、调试结果
