unable to open initial console - porting linux 2.6.15.4 on AT91RM9200 board

absaxena — 2007-07-23T04:21:55+00:00

Hi,
We have been trying to port linux (2.6.15.4) on to a AT91RM9200 board. The kernel boots properly but is unable to bring on the rootfilesystem. Linux 2.4 has been running on this board quite successfully.

We are wondering if anyone faced a similar problem and could provide some suggestions for troubleshooting. Earlier, we tried some suggestions available on the web; unfortunately none of them worked for us.

Relevant details are attached.
A. Boot trace
B. kernel config file
C. Busybox config file

Thanks,
Anshuman

A. Here is the boot trace:

Re: why separate initramfs

It's used all the time in Debian. For example, upgrading udev or other utilities, adding or removing uswsusp support (suspend functionality) or the various splash screen programs, etc. Very useful.

Re: the initrd is actually an initramfs

ldo — 2006-11-27T06:24:03+00:00

Of course, you wouldn't need a special boot-time utility for this, you could do the cleanup at your leisure afterwards, if only something like this were permissible:

mount -t rootfs rootfs /mnt

But this appears to be ruled out by the NOUSER flag...

Re: why separate initramfs

>That does make some sense, but I've never seen that capability used.

On the contrary. Look at most binary-based Linux distros (that is, most Linux distros), for example (looking at ones on machines I have immediate access to) SuSE or Red Hat. They tend to come with only a small selection of pre-built kernels to choose from. But rather than build in every driver you might need at boot time into the kernel, you have to make an initrd that includes the necessary kernel modules that will need to be loaded even before the root filesystem can be mounted.

giraffedata — 2006-11-26T00:38:06+00:00

One other interesting point about early root filesystems: In a latter day 2.4 kernel, there is a root filesystem even earlier than the initial ramdisk one (initrd). rootfs is built into the kernel, and always contains a handful of filesystem that you need to get up far enough to load and mount the initrd filesystem (the root directory and a few device special files, as I recall). And it never gets unmounted; it's always down there with the real root filesystem mounted over it.

I don't know 2.6 booting, but it sounds from the article like 2.6's rootfs is an extension of this.

Embedded Linux: Small Root Filesystems

giraffedata — 2006-11-26T00:31:41+00:00

initrd and initramfs are separate things and work quite differently. Notably, initrds are whole filesystem images, so once you're done with them you have to get rid of them (hence the nasty pivot_root(2) kludge ...

I don't get the distinction. First of all, there's some confusion because "filesystem image" means two different things.

On the one hand, it's the entity that you create when you mount and destroy when you unmount, and by that definition the rootfs filesystem image (which gets loaded with files from a cpio archive) doesn't seem any less whole to me than the initrd filesystem image. pivot_root() allows you to unmount an initrd filesystem, thus destroying it and freeing its memory as well as removing its names from the namespace. Why don't you need to do that with initramfs?

In its other meaning, a filesystem image is a copy of the bits that make up a filesystem, such as what the boot loader uses to convey initrd contents to a 2.4 kernel. Pivoting has nothing to do with getting rid of that kind of filesystem image. And it's equivalent to "getting rid of" the cpio archive used with initramfs.

Re: the initrd is actually an initramfs

landley — 2006-11-26T00:11:08+00:00

The switch_root utility essentially does:

cd newroot
find / -xdev | xargs rm -rf
mount --move . /
chroot . /sbin/init

This frees up the space used by the initramfs by deleting all the files
before switching to the new root device. (With ramfs, deleting the file
frees the memory.)

The reason you can't do this in a shell script is after the "rm -rf" step,
the shell script hasn't got a "mount" command to run anymore...

Re: why separate initramfs

landley — 2006-11-26T00:06:23+00:00

If you build an initramfs in and then supply an external one, the external
one gets extracted over the built-in one, with the external one winning in
case of any conflicts (replacing those files).

So you can always add an external initramfs with _just_ the changed files.
Ubuntu's providing an external one because their developers learned with
initrd and have established habits.

Thalience — 2006-11-25T17:28:45+00:00

Re: the initrd is actually an initramfs

ldo — 2006-11-24T01:43:36+00:00

You're right! I checked the initrd on my SuSE 10.0 system, and it is in fact a compressed cpio archive! No wonder I had no luck trying to mount it as a loopback image :).

Another thought, though: with the old loopback initrd, all the memory used was freed after the pivot_root and the dismount. But with the initramfs mechanism putting things into rootfs, those things stay there, taking up memory, being only hidden when the real root filesystem is mounted on /. Does that make sense?

So that it's easier to update the kernel and the initramfs image separately, of course.

Thalience — 2006-11-23T23:37:17+00:00

It does seem to be the case that inclusion is optional. On my Ubuntu Edgy system, /boot/initrd.img-2.6.17-10-generic is a compressed cpio archive, not an ext2 image or whatever.

What I don't know is why they create a separate initramfs, rather than building it into the kernel image.

initrd in 2.6

ldo — 2006-11-23T08:09:25+00:00

The article seems to suggest that initrd is no longer used with 2.6 kernels. In fact initrd is still available with 2.6, and is used instead of initramfs by Red Hat and SuSE, that I know of.

Embedded Linux: Small Root Filesystems

zipdisk — 2006-11-23T05:41:52+00:00

You missed a very used way to easily construct a small root filesystem,
the cousin of busybox: buildroot. Basically it will create a full small
root file system "a la carte", based on uclibc, busybox and some other
applications.

And don't forget...

The new initramfs system

smitty_one_each — 2006-11-22T14:05:42+00:00

The kernel path is what's passed to GRUB. Think of the kernel image as an egg with a shrunken initramfs chicken stashed in it by the kbuild system.

Well worth perusing:

The new initramfs system

rvfh — 2006-11-22T12:35:49+00:00

Just one question: if initramfs is built inside the kernel, what is passed to GRUB (with the initrd option) in my distribution? Or is the inclusion optional?

Embedded Linux: Small Root Filesystems

nix — 2006-11-22T11:26:52+00:00

One point that was perhaps not made strongly enough is that pivoting is an initrd thing *only*. initrd and initramfs are separate things and work quite differently. Notably, initrds are whole filesystem images, so once you're done with them you have to get rid of them (hence the nasty pivot_root(2) kludge, the even nastier echo-stuff-into-a-file-under-/proc kludge, and so on). None of this is necessary with initramfses, although the busybox switch_root tool remains useful (principally because deleting the contents of the initramfs would leave a shell script rather stuck when it came to chrooting into the real root filesystem).

I'd also recommend linking busybox (and anything else on your initramfs) agaisnt uClibc or some other tiny libc, and linking it statically, because when you only have one or two binaries, the savings from avoiding inclusion of unused symbols exceed the space wasted by duplicating those symbols in many binaries.

Using initramfses is particularly important for those of us who boot from filesystems that require userspace support to bring up, such as LVM or md/raid with v1 superblocks. It also means you can fsck the root filesystem *before* mounting it (it's always seemed icky and dangerous to me to fsck any mounted filesystem, and why should / be different?).

Also, the extra flexibility makes it really easy to hack in new features on demand. When I had a double disk failure earlier this year, it was a matter of a few minutes' work to bring up the network block device before mounting /; then I could distribute the RAID array containing the root filesystem partially onto another machine across the network. (Of course this was a real kludge and not desirable for long-term use: among other things, because nbd uses TCP/IP connections, whenever the remote machine rebooted, the root filesystem on the local one vanished too: but it meant I could keep running after a fashion until the disks were replaced.)

Plus, because initramfses are built into the kernel, if you have a modular kernel you don't need to worry about the modules getting out of synch with the kernel you're running. (In my experience this was a persistent headache with initrds.)
