Bummer, could not run '/etc/init.d/rcS': No such file or directory

- x bits set for this shell script?

- does a shell run?

- try init=/bin/sh as a kernel parameter. Does it run?

- all needed libraries to run available on your target?

- x bits set for this shell script? SInce Iam new to this embedded linux, could you tell whats that x bits means, is it exec permission (if so for whom,root?).

I couldnt put my data here, so Iam continuing the discussion in new discussion

- x bits set for this shell script? SInce Iam new to this embedded linux, could you tell whats that x bits means, is it exec permission (if so for whom,root?).

- does a shell run? Iam not clear why does it say /etc/init.d/rcS is not there, while its definitely there. I feel shell is not running. I want to just put what I get in minicom

- try init=/bin/sh as a kernel parameter. Does it run?

guide me where Iam wrong Prakash

Yes, exec permissions. Try to enable them for all (user, group and world). But I think this is not the problem you have...

To run /etc/init.d/rcS a shell interpreter is required. That's why I asked if at least your shell is running.

But I think it runs, as you are using busybox. And "init" and "sh" are the same binary.

With this kernel parameter you start a shell instead of "init". So there should be no more a login and you can deltete root's password for the future. What kind of bootloader do you are using?

Sorry for this kind of reply, as there are some problems in google, not allowing to send more data. - try init=/bin/sh as a kernel parameter. Does it run? My init tab file is

---------------------------------------------------------------------------------------------------------------------------- ::init=/bin/sh ::sysinit:/etc/init.d/rcS #::askfirst:-/bin/sh ::ctrlaltdel:/sbin/reboot ::shutdown:/sbin/swapoff -a ::shutdown:/bin/umount -a -r ::restart:/sbin/init ::respawn:/sbin/getty 9600 tts/0

The log is .......... VFS: Mounted root (ext2 filesystem). mount_devfs_fs(): unable to mount devfs, err: -5 Freeing unused kernel memory: 60k init Warning: unable to open an initial console. Kernel panic: No init found. Try passing init= option to kernel. Rebooting in 180 seconds..

Not your inittab, instead kernel parameter "init=/bin/sh" replaces the init process by a shell.

What and where is your filesystem?

Hmmm, what is that? It seems there is nothing in your root filesystem. devfs tries to mount itself on /dev, but there is no directory with this name.

There is no /dev/console device node in your root filesystem, consecutive fault from previous devfs failure.

And at least there is no init binary to execute. Your rootfs is empty. What did you change? In your last mail you where able to boot up to the login prompt????

Check this: $ readelf -d your-busybox-binary

It lists the required dynamic libraries to execute this binary. Are they

*all* on your target rootfs? Note: Instead of "readelf" you should use the cross variant of this command.
