Sl-c3000 Initrd Image Options

[xenophobe]

Is initrd image for SL-C3000 somewhere in Inet?

I try to understand booting process and MD management on SL-C3000 and port it to SL-6000. But I don't have SL-C3000 :-(.
Can somebody help me and post link to initrd image or tarred /etc directory?

This url, put together by 'pelon' is probably going to serve your needs.

http://www.xlfag.com/zaurus

It contains a link to a hdd1.tar.gz file which contains the files from the first partition of the hard disk.

Initrd is something else and contains the basic modules that are needed to boot a system if they aren't directly linked into the kernel, I think this is actually stored in the NAND image and since there is no CF/SD based update out for the SL-C3000 yet the NAND based OS file system is probably only accessable by mounting that NAND partition... I don't have one yet so I can't help you there.

I have this file, but unfortunatly it does not contain most interesting part - /etc directory.

I have NAND backup image from http://www.xlfag.com/zaurus

Is NAND a plain FLASH memory dump? And what is SL-C3000 memory layout?
Can I cut mtdblock3 part from this NAND and mount it as JFFS2?

At a Linux desktop logon as root or su.

First check to see if you have a device called /dev/mtdblock0, if not then you want to...

mknod /dev/mtdblock0 b 31 0

then...

losetup -o 7576608 /dev/loop0 SYSTC300.DBK
modprobe mtdcore
modprobe jffs2
modprobe mtdram total_size=32768 erase_size=256
modprobe mtdchar
modprobe mtdblock
dd if=/dev/loop0 of=/dev/mtdblock0
losetup -d /dev/loop0
mount -t jffs2 /dev/mtdblock0 /mnt/test

Substitute your mount point in the last line.

Its a funny looking root with an initially sparse populated etc directory located in home/etc. Top level etc appears to be a script!

Have fun,

I had tried to follow your instruction exactly, except

losetup -o 7576608 SYSTC300.DBK

I use
losetup -o 7576608 /dev/loop0 SYSTC300.DBK

But I got "Segmentation fault" on mout. and dmesg returns:

If you can mount SYSTC300.DBK on your linux box by following your instructions, pls. tell me what is your kernel version and linux distro.
My is

[root@justtesting log]# uname -a
Linux justtesting 2.6.10-1.766_FC3 #1 Wed Feb 9 23:06:42 EST 2005 i686 athlon i386 GNU/Linux

and my distro is Fedora Core 3.
But I can change kernel to some of previous versions.

Eugene, well spotted on the typo (/dev/loop0 on the losetup command - updated the post for future reference)

I'm using SuSE 9.2 with all the latest patches and it works fine.

If you have a DVD burner then you might want to try the Live DVD or I'm sure that 'Linux User' or one of the magazines on the shelves probably has a Live DVD of the distro.
