[U-Boot-Users] 2.4.19-rmk7-ds1+JFFS and U-Boot.
Hi...
I am trying to load jffs file system from my flash in my ixdp425 board. my kernel shows...JFFS file system is mounted. but there is no prompt there.
I want to know, whether i m following correct steps with u-BOOT or not.
1. created jffs file system using mkfs.jffs2 (mkfs.jffs2 -e 0x20000 -b -r /root/Prakash/RAMD/temp/ -o ram.img. ) 2. made the ram.img as ram.uimg using mkimage -T ramdisk -C gzip -a 0x00440000 option. (My kernel boot message shows 0x0044000 as user partition.so that i m using it for RF.)
3. Made ram.uimag as srec file. and downloaded into flash at 0x50160000.
Now i m passing the following as my command line args.
=root=/dev/mtdblock1 mem=16M rootfstype=jffs console=ttyS0,115200 init=/bin/sh
kernel bootup message...
...... Using static MTD partitions. Creating 2 MTD partitions on "IXP425 Flash": 0x00040000-0x00440000 : "image" mtd: Giving out device 0 to image 0x00440000-0x00fc0000 : "user" mtd: Giving out device 1 to user .... ....
VFS: Mounted root (jffs filesystem). Freeing init memory: 204K Warning: unable to open an initial console. Kernel panic: No init found. Try passing init= option to kernel.
Expecting ur help
I m struggling with this problem last 5 days.
Thanks Prakash

You must learn to be more precise. Please pay attention to all details, may they be little or not.
1. created jffs file system using mkfs.jffs2 (mkfs.jffs2 -e 0x20000 -b -r /root/Prakash/RAMD/temp/ -o ram.img.
This is wrong. This does not create a JFFS filesystem.
It creates a JFFS2 filesystem, which is something different.
Also, the name "ram.img" is misleading at best.
2. made the ram.img as ram.uimg using mkimage -T ramdisk -C gzip-a 0x00440000 option.
What should that be good for? There is no use in adding a mkimage wrapper around a filesystem image.
Now i m passing the following as my command line args.=root=/dev/mtdblock1 mem=16M rootfstype=jffs console=ttyS0,115200 init=/bin/sh
This is wrong again. Since you created a JFFS2 image, your filesystem type is NOT jffs. It is jffs2.
I m struggling with this problem last 5 days.
Why don't you try working on ONE configurtation only, and get this running? Fighting a war on two or more fronts is not that easy.
