如何在上加入NandFlsah的Jffs2工具?

HelecXu

大侠们帮忙:如何在mizi-Linux2.4.19上加入NandFlsah的Jffs2工具mkfs.jffs2等...

我最近刚从深圳远峰那搞了一块AT91RM9200的ARM9开发板,上面没有eraseall等的工具,在网上下载了MTD的工具可都是Linux2.6的核,配置不成功就没有往下做,能否从贵处得到指点帮忙,菜鸟HelecXu谢谢你,如有相关工具源码----> [email protected]嘿嘿!在网上太难搞,好多都要看英文,累....

修改了部分代码,启动相关信息如下:
NAND device: Manufacture ID: 0x52, Chip ID: 0xec (Samsung K9F5608U0B) // 修改过驱动.
Creating 6 MTD partitions on "Samsung K9F5608U0B":

在/dev/mtd 和 /dev/mtdblock可以看到挂接的设备了,
# cd /dev/mtd
# ls

0ro 1ro 2ro 3ro 4ro 5ro 6ro 7ro 8ro

# cd /dev/mtdblock
# ls

# cat /proc/mtd

用mount -t jffs2 /dev/mtdblock/5 /mnt/jffs2时显示了无数行信息:最后几行如下:
