This one can't be me...

This one can't be me...

[Paul D. DeRocco]

I've successfully built core-image-base-cedartrail-nopvr, with NO
modifications, no meta-oe layer to pull in Samba, no attempt to partition
the flash drive, just the .hddimg file dd'ed to /dev/sdb, to see if I can
get something, anything to boot out of the box.

I get a kernel panic when it tries to boot on my Intel DN2800MT mobo, with
1GB of RAM. The error messages, which appear on the attached VGA monitor,
are:

VFS: Cannot open root device "ram0" or unknown-block(0,0)
Please append a correct "root=" boot option;
here are the available partitions:
VFS: Unable to mount root fs on unknown-block(0,0)
User configuration error - no valid root filesystem found

Here is the syslinux.cfg file that is controlling the boot:

# Automatically created by OE
serial 0 115200
ALLOWOPTIONS 1
DEFAULT boot
TIMEOUT 10
PROMPT 1
LABEL boot
KERNEL /vmlinuz
APPEND initrd=/initrd LABEL=boot  root=/dev/ram0   console=ttyS0,115200
console=tty0 video=vesafb vga=0x318
LABEL install
KERNEL /vmlinuz
APPEND initrd=/initrd LABEL=install  root=/dev/ram0   console=ttyS0,115200
console=tty0 video=vesafb vga=0x318

This is a live-image boot, and the flash drive contains the usual five
files. As far as I can tell, a live-image boot is a two-stage boot beginning
with a really stripped down vmlinuz and a small RAM-disk read from initrd,
which then reads the big rootfs.img into another RAM-disk and tries to boot
the real kernel from that. I don't know which kernel is panicking, because
it all flies by so fast.

Any ideas, or am I cursed?

Followup:

I figured I'd try a sato build, since that's what the example on the BSP
page uses. But core-image-sato-cedartrail-nopvr panics in the same way as
core-image-base-cedartrail-nopvr. For sato, I surmised maybe 1GB wasn't
enough, so I put in a second stick. This time, instead of spewing out a lot
of kernel startup stuff ending in a panic, it gave me a SYSLINUX signon on
the top of the screen, sat there for about 10 seconds, then rebooted into
the BIOS, repeatedly. So I put back core-image-base-cedartrail-nopvr, and it
also gave me the SYSLINUX signon, and rebooted after 10 seconds.

The fact that it behaves differently with 2GB suggests that maybe 1GB isn't
enough, but that seems hard to imagine even for sato, let alone the base
console version. I've run Ubuntu on these particular RAM modules, on a
different motherboard, so I don't think I've got bad RAM.

Any help figuring this out would be appreciated. For all my work, and
apparently successful builds, I haven't managed to boot anything yet.

Hi Paul,

First off, please CC the relevant maintainers of the recipes and BSPs
you are having trouble with. The README in the cedartrail BSP lists
Kishore as the maintainer, now on CC. This will help improve response
time to your post as well as getting the right people looking at it.

Kishore, can you please work with Paul to get him booting?

Some ideas on things to check/try inline below.

Believe it or not, this is the single most common boot error in the
history of boot errors on Linux :-)

It is telling you there is no block device called "ram0" to load and
there are no other block devices detected. The USB stick doesn't show up
here because USB can take a while to enumerate and unless you tell the
kernel to wait for it, it doesn't. That shouldn't be your problem here
as you are attempting to boot from a ramdisk.

The most obvious question is whether or not the kernel you built has
ramdisk support. You can do this by analyzing the .config file in your
linux-yocto build tree
(build/tmp/work/cedartrail.../linux-yocto*/linux-cedartrail-standard-build/.config).
You want to look for:

$ grep BLK_DEV_RAM .config
CONFIG_BLK_DEV_RAM=y
CONFIG_BLK_DEV_RAM_COUNT=16
CONFIG_BLK_DEV_RAM_SIZE=4096

Well, see my comment above, the kernel was about as explicit as it can
be - it didn't find a block device to mount as root. However, when
debugging kernel issues, it is important to be able to record the log.
You have a serial port console configured in your kernel parameters
(console=ttyS0,115200), it would be a good idea to connect to the serial
console and capture the boot messages to a file using minicom, screen,
or similar.

Another common problem is the hddimg format itself and conflicts with
certain firmware. You can try the zip image format as described in
poky/README.hardware under the "Intel Atom based PCs and devices" section.

Finally, usb sticks are terrible about just being bad. Many of them are
literally write once devices. They're fine so long as you don't fill
them up, which works for shuffling small files around, but writing full
OS images to them tends to kill them in a hurry. Try with a brand new stick.

Hi Paul,

The live images boot in (roughly) the following way:

1- BIOS loads the bootloader (syslinux)
2- Bootloader loads the kernel and initrd
3- Kernel starts and executes the 'init' script from the initrd
4- The 'init' script mounts sysfs, devtmpfs and procfs filesystems and
   starts udev. It then waits for a storage device containing the
   rootfs.img file to appear (udev rules will mount the device in
   /media).
5- Once the file (rootfs.img) appears it loop-mounts and switch_root to
   it to continue the booting process.

BTW, there is only _one_ kernel. The two stage process allows more
flexibility as where your rootfs is located (CD, usb flash, network
boot, etc.).

From what I see in the kernel messages you supplied it looks like the
init script doesn't even got a chance to run. Kernel issue?

One strange thing also is the use of the 3.0 kernel on this BSP. Which
doesn't shows up in the list of available kernels (well at least on the
git.yoctoproject.org web site.) so I don't know what happens in such
cases.

It would definitely help if the maintainer of the cedartrail BSP could
drop-in and give some advice!

Good luck,

Marc

Thanks Darren, will follow up on this.

Hi Paul, 
Please try out what Darren has suggested.

That directory (full path is
/home/pauld/yocto-atom/build/tmp/work/cedartrail_nopvr-poky-linux/linux-yoct
o-3.0.32+git1+a4ac64fe873f08ef718e2849b88914725dc99c1c_1+1e79e03d115ed177882

completely empty. Yes, I know it's supposed to be a hidden file. This is
right after completing a "successful" build of core-image-sato.

Done. Attached.

Tried that, same result.

Tried a fresh one, same results. I'm using a 1GB eUSB SSD, which is
basically an industrial grade flash drive that uses SLC memory, on a card
that sits on the mobo USB header. The image doesn't come close to filling it
up. I've successfully done a live-image boot of full Ubuntu from the 2GB
version of the same drive (same vendor).

It smells to me like that first problem is the real one. Should I try a
clean rebuild? Is there anything I can do short of nuking the entire build
tree with its downloads to ensure a clean rebuild? Or would that be like
waving a dead chicken over it?

Are you building with the rm work setting? Otherwise, that should not be
empty unless you have more than one linux-yocto* directory and the other
is populated.

If not, verify rm work is not on and just build the kernel:

$ bitbake linux-yocto -c cleansstate
$ bitbake linux-yocto

Nothing in there suggests any other failure than it just didn't find a
block device. I didn't see anything in there about loading the initrd
though (I think there usually is...). Check to make sure the initrd file
does indeed exist on the boot drive.

That would hint at either a problem with the initrd or a lack of support
in the kernel.

The nuke is the big hammer, try the slightly more subtle linux-yocto
rebuild without rm-work as described above.

That option is off, and there is no other linux-yocto* directory.

The first line says there is no do_cleanstate task for linux-yocto, and so
the second line finds nothing to do. Is there another way to force that?

Yes, it does.

It's surprising that you don't see anything under 
/home/pauld/yocto-atom/build/tmp/work/cedartrail_nopvr-poky-linux/linux-yoct
o-3.0.32+git1+a4ac64fe873f08ef718e2849b88914725dc99c1c_1+1e79e03d115ed177882
ab53909a4f3555e434833-r4.1/linux-cedartrail-nopvr-standard-build

It means that Kernel is not getting build for you?
How come you were able to generate the .hddimg and trying to boot?

Do you have the rootfs under build/tmp/work/Cedartrail*/core-image-sato/?

Thanks
Kishore.

This doesn't make any sense. Can you send the actual output rather than
interpreting please?

Oh, actually, please read the command more carefully, there are two ss's in
cleansstate.

After doing that (with two esses), I now have a .config file, along with a
ton of other stuff, in that folder. I have no idea what made it disappear,
because I don't use the rm_work option.

However, the only BLK_DEV_RAM line is

	# CONFIG_BLK_DEV_RAM is not set

I haven't been fiddling with the kernel, because I don't know how to fiddle
with the kernel. This should be a plain vanilla build.

Some gremlin made that first directory go away. I've successfully rebuilt
it.

There is a rootfs directory in the second directory, and it contains things
like /dev/ram?. I captured a tree listing of my build a while back, and it
had those device nodes, too.

If I loop mount the .ext3 file that my panicking build produced, it has
/dev/ram? device nodes, too.

I believe those are generated by devtmpfs anyway.

So that would result in this exact failure. Kishore, can you verify the
BSP linux-yocto meta-data and either fix the BLK_DEV_RAM issue or help
Paul sort out what he may have done that resulted in this breakage?

Hi Paul,

While I do the check and verify at my end, can you enable the missing configs by 
Menuconfig?

bitbake  -c  menuconfig  linux-yocto
bitbake  linux-yocto.

Thanks
Kishore.

Hi Bruce/Darren,

I do not see Linux-yocto-3.0 kernel branch in git repo.
Is it no longer available?
Cedartrail BSP for 1.3 Yocto (danny) supports only 3.0 kernel.

I am not sure how Paul is able to build this bsp?

Thanks
Kishore.

The clean build didn't solve the problem. Here's what I did:

Re-downloaded and extracted poky-danny-8.0 and meta-cedartrail-danny-8.0.0
from the Yocto web site into a new directory.

In a new terminal window, ran oe-init-build-env to create the empty build
directory and default config files.

Moved the old downloads directory into the new build tree.

Added the meta-intel and meta-intel/meta-cedartrail layers to bblayers.conf,
after the other layers.

Inserted the following two lines at the beginning of local.conf:

	MACHINE ?= "cedartrail-nopvr"
	BBMASK = "meta-oe/recipes-support/guile"

The last line was a necessary fix for a bug that occurs when I add Samba
from OpenEmbedded, but since that tree of metadata isn't currently included,
this should match nothing and change nothing.

The build was successful, although I still get those NOTEs about "preferred
version 3.4% of linux-yocto not available". Yet it still panics on boot, for
lack of a ram drive.

The only possible corruption at my end, then, is in my downloads.

Here are the config parameters for the clean build that I am doing now.

kishore@kishore-desktop:/usr/local/src/cedartrail/build/tmp/work/cedartrail_nopvr-poky-linux/linux-yocto-3.0.32+git1+bf5ee4945ee6d748e6abe16356f2357f76b5e2f0_1+1e79e03d115ed177882ab53909a4f3555e434833-r4.1/linux-cedartrail-nopvr-standard-build$ grep BLK_DEV_RAM .config
CONFIG_BLK_DEV_RAM=y
CONFIG_BLK_DEV_RAM_COUNT=16
CONFIG_BLK_DEV_RAM_SIZE=4096

I don't understand how these are missing in your build?  BLK_DEV_RAM are enabled for Cedartrail-nopvr build.

What did you do different?

Thanks
Kishore.

I don't know. I detailed the steps I took. I still have

	# CONFIG_BLK_DEV_RAM is not set

Does the order of the layers in bblayers.conf matter? Is it possible that
something in the past fetched a different version of something, and it's
sitting in my downloads tree and screwing things up?

I'm sending you the two build log files separately, so that they don't go
out to the entire list.

I did a clean build and booted N2800 board.
Sato desktop comes up.
No issues here.

I believe you. To reiterate my last questions: does it matter what order the
layers are specified in bblayers.conf? If not, is deleting the downloads
tree and doing another build the only thing left to try?

I have the build working with this bblayers listing:

BBLAYERS ?= " \
  /home/usr/Yocto1.3/poky-danny-8.0/meta \
  /home/usr/Yocto1.3/poky-danny-8.0/meta-yocto \
  /home/usr/Yocto1.3/poky-danny-8.0/meta-intel \  
  /home/usr/Yocto1.3/poky-danny-8.0/meta-intel/meta-cedartrail \
"

I have never tried switching them around, but I don't see how it matters

Can you send those to me as well, along with your entire bblayers.conf

I have meta-yocto-bsp in there, too, because that was part of the default
configuration file. Is that wrong?

I'm seeing the same thing here (# CONFIG_BLK_DEV_RAM is not set) with
your bblayers and local.conf.  For some reason the base and
standard .cfgs aren't being applied to the .config.  I'll have to dig
around further as time permits over the weekend...

Thanks, although this might be floobydust. I've nuked the _entire_ build
tree, included downloads, and am trying a rebuild from scratch, but that
will take until tomorrow morning to complete, since I'm doing the build on
an Atom. If it somehow solves the problem, I'll let you know, so you don't
waste your time chasing unicorns. But if it doesn't solve the problem, your
help would definitely be appreciated. I've been trying to get a build, any
build, to boot for a really long time now.

My guess is there's a real problem here, since I'm able to reproduce it
with my own downloads dir and a rebuild from scratch.  Now that I have a
reproducer, I'm pretty sure we'll be able to nail down the problem and
at least get the kernel part right - if the kernel is missing config
like this it just won't boot, plain and simple, so we need to get past
that first and chances are it will be smoother sailing after that...

And as a FYI: I'm tracking down an issue with configs at the moment as
well.

I can try this board to see if I get the right configs in my final .config
once I've tracked down the issue.

It looks like the problem is a bad SRCREV for the meta branch in the
-nopvr machine in the cedartrail danny tarball.  Try changing the
following line in
meta-cedartrail/recipes-kernel/linux/linux-yocto_3.0.bbappend:

SRCREV_meta_pn-linux-yocto_cedartrail-nopvr ?= "a4ac64fe873f08ef718e2849b88914725dc99c1c"

to

SRCREV_meta_pn-linux-yocto_cedartrail-nopvr ?= "bf5ee4945ee6d748e6abe16356f2357f76b5e2f0"

Changing that got me a .config with the correct CONFIG_BLK_DEV_RAM
setting.

Ta-da! That fixed it.

I'm glad the subject of this thread didn't come back to bite me.

Thanks so much for your time in figuring this out.

Sure, glad that worked out...

And of course the cedartrail tarball should be updated as soon as
possible with at least that change - this shouldn't have been a problem
in the first place (also should add the missing preferred provider and
avoid the other warning as well).  Cc:ing the maintainer for that...

Do you mean you don't see the linux-yocto-3.0 recipe? It was removed in
later releases, but is still available in danny.
