*mount fs type jffs2 not supported by the kernel.*

Please read the section on how to enable Jffs2 in the kernel - make menuconfig, filesystem, check for MTD if flash driver is enabled etc..

If u dont have jffs2 available consider using ramdisk option too if ur filesystem is small and you dont care about files generated/modified after bootup.

Hi,
In the howto from oskfordummies a 2.6 kernel is recommended. Anyway, I supose you just have to recompile the kernel with jffs2 filesystem support and reflash it to the osk 5912 board.
Nevertheless...why are you reflashing the board if you are using the original montavista preview kit? Why not just download a .tar file with your application to the board original filesystem?

Dear Nishanth,
I followed up the steps in the mail what u have
sent for my query. I went through the documentation and copied the filesystem to the flash. I m using the kernel 2.4.20-8.While mounting the filesystem to */mnt/flash*, the following error occurred.
*mount fs type jffs2 not supported by the kernel.*
In the OSK5912 guide, it is mentioned to use redhat 7/9.Could
you tell me the way to get jffs2 for kernel 2.4.20-8 or any changes to be done to get the solution for the above problem? Waiting for your positive reply.

To flash it use the uboot itself(if u already have one uboot on board) - it should support flashing options. Protect off, erase , cp commands should be good enough for NOR flash. There is help for the same within uboot itself (type help at uboot command prompt)
Or u can use the ost host tool as described in the oskfordummies.

Ok.. I assume that u would like to download kernel? Or do u want to download a filesystem? Let me try either one of them Onboard, u can use the loadb command that can take a file (uImage/uboot.bin/some bin) over serial port using Kermit. Once u have a filesystem (either ramdisk/jffs2 based flash/nfs filesystem) u can boot ur kernel. But a kernel alone will not be of much use to u. the apps need to reside on the filesystem. Once u have the filesystem is available and u have some sort of prompt, check the filesystem apps available. They should behave as if you are on a normal linux box.

Hi,

While mounting the filesystem using NFS, the following error occurred. DHCP
configures the IP address properly(192.168.0.150). What could be the problem?

Looking up port of RPC 100003/2 on 192.168.0.121

Looking up port of RPC 100005/1 on 192.168.0.121

Root-NFS: Server returned error -13 while mounting /tftpboot/serverip:/home/sach

in/montavista/filesys

VFS: Unable to mount root fs via NFS, trying floppy.

VFS: Cannot open root device "nfs" or 02:00

Please append a correct "root=" boot option

Kernel panic: VFS: Unable to mount root fs on 02:00

Please provide a solution for this problem.
Thanks in advance,
B.Nagarajan,
SANDS.
