Re: Building rootfs for arm target
Hello
emdebian-arm.tgz is a rootfs, that can be used via NFS or converted to
any other filesystem.
to create a jffs2 image you need mkfs.jffs2 provided by mtd-utils
(probably a package to suggest by emdebian-rootfs or emdebian-utils ?):
$ sudo apt-get install mtd-utils
$ /usr/sbin/mkfs.jffs2 --help
mkfs.jffs2: Usage: mkfs.jffs2 [OPTIONS]
Make a JFFS2 file system image from an existing directory tree
=> now you are able to create your own jffs2 image
the setup of a NFS Server environment to mount the rootfs via NFS is
strongly recommended, that makes working on embedded Linux much easier!
Regards
Roger
