Message: 54920 Hi everyone

I have install uclinux on ezkit 533,and send a driver module to the ezkit, the driver module is globalmem.ko,and it's major is 210, then i execute command and the result show as follow:

root:/var> insmod globalmem.ko

root:~> mknod /dev/globalmem c 210 0

mknod: /dev/globalmem: Read-only file system

so I want to mount a filesystem which can be read and write such as jffs2

I find the jffs2.ko in this directory /lib/modules/2.6.19.3-ADI-2007R1-pre-svn/kernel/fs/jffs2/jffs2.ko on ezkit 533

How to slove this problem? How to mount jffs2 on ezkit533?

Hong

Message: 54923 if you want a writeable root filesystem, simply remount it or use the right kernel commandline options

for jffs2, please review the documentation:
