Where did you get "fsimage.tar" from?
I made it using info obtained from MontaVista Support. Essentially I used thier Target Configuration Tool - the script is pasted below. An excerpt from the tech support follows:
We recommend using TCT to build a root filesystem image. The program you use is /opt/hardhat/host/bin/targetconf.
If you need a non-GUI tool to build an initrd, we have one that is used with our Compaq iPAQ LSP. This is not supported for general use in creating ramdisk images, but it should work for you, and I've provided it here.
Instructions:
1. If you've relocated your MontaVista Linux installation to somewhere other than the default location (/opt/hardhat/...), then you need to edit the script and change the line
basedir = "/opt/hardhat"
to point to the correct base directory for your installation.
2. ctargetconf can only be used to build a filesystem. It will not build a kernel as is done in targetconf.
3. Create a project in TCT but do not include a "Custom kernel". Basically, you are creating a TCT project that will only build a filesystem, i.e.,
New Project -> (Fill in proper fields in "TCT: New Project" window, select LSP, ***BUT*** make sure to unselect "Use Custom Kernel"). Then create a config file and choose all desired packages. Save the config.
4. From your TCT project directory, copy the .project and *.cfg file to your working directory where ctargetconf is located.
5. Build a filesystem image.
./ctargetconf -c test1.cfg -o fsimage.tar
To see command options, just do,
./ctargetconf
6. Making the initrd image:
The above builds a tarball of the files in the root filesystem. To make an actual initrd image, you have to make a file of the correct size, make an ext2 filesystem on this file, mount the new filesystem, copy (preserving symbolic links) the files from your tarball into the new filesystem, then unmount the filesystem, sync, and compress the filesystem. The following makes a 16 MB ramdisk image from fsimage.tar:
mkdir mountpoint dd if=/dev/zero of=ramdisk bs=1k count=16384 /sbin/mke2fs -q -F -m0 ramdisk mount -o loop ramdisk mountpoint cd mount tar xf fsimage.tar sync sleep 1 sync cd .. umount mountpoint sync gzip -9 ramdisk
What does it contain.
tar -xvf fsimage.tar ls -al total 36 drwxr-xr-x 9 root root 4096 Apr 1 18:27 . drwxr-xr-x 4 root root 4096 Apr 1 18:11 .. drwxr-xr-x 2 root root 4096 Apr 1 18:11 bin drwxr-xr-x 2 root root 4096 Apr 1 18:11 dev drwxr-xr-x 6 root root 4096 Apr 1 18:11 etc drwxr-xr-x 2 root root 4096 Apr 1 18:11 lib drwxr-xr-x 2 root root 4096 Apr 1 18:11 sbin drwxr-xr-x 5 root root 4096 Apr 1 18:11 usr drwxr-xr-x 4 root root 4096 Apr 1 18:11 var
Ummm... I don't even see a filename here. I don;t see if there is an "init" binary or a shell or any library or any device.
Sorry about that - I need to learn how to cut and paste properly ;-)
Which sort of output do you expect when providing such input? GIGO...
I expect none - it was a mistake.
The mounted volume contains:
ls -al mountpoint total 26 drwxr-xr-x 10 root root 1024 Mar 20 15:34 . drwxr-xr-x 4 root root 4096 Apr 1 18:28 .. drwxr-xr-x 2 root root 1024 Mar 20 15:34 bin drwxr-xr-x 2 root root 2048 Mar 20 15:34 dev drwxr-xr-x 6 root root 1024 Mar 20 15:34 etc drwxr-xr-x 2 root root 2048 Mar 20 15:34 lib drwxr-xr-x 2 root root 12288 Mar 20 15:34 lost+found drwxr-xr-x 2 root root 1024 Mar 20 15:34 sbin drwxr-xr-x 5 root root 1024 Mar 20 15:34 usr drwxr-xr-x 4 root root 1024 Mar 20 15:34 var
