FW: How to implement JFFS2 filesystem on NAND

[sathish.madhava]

Hi,
I changed my rootfs.

But now I am getting the error message as below.

++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++
jffs2_scan_eraseblock(): Magic bitmask 0x1985 not found at 0x00088024:
0xcf4e instead
Further such events for this erase block will not be printed
VFS: Mounted root (jffs2 filesystem).
Freeing init memory: 124K
++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++
And it stops here.

I have included console in my /dev.

How to go about it now.

Looks like your file system has no device nodes in /dev.

For older kernels devfs would allow this to work.  On newer ones you
need all your nodes, or a properly configured udev, and some hotplug
support.

you dont have a jffs2 image in the device you gave it to / part of the
flash is empty.. Suggestion on jffs2 filesystem - use a working
filesystem - the same filesystem should work fine either as a RAMDISK(if
it is small) or as a NFS filesystem.
If this is proven, then another observation i have had in the past is
that certain flash parts might take a bit longer on the very first
mount(boot)- something like 20-30 mins.. give it an hr and see if the
garbage collector finished it's work.
