compiled kernel for rb532, dd'd kernel to 1st CF partition, cp'd unpacked rootfs to 2nd CF partition, kernel boots semi-ok and fails at:

VFS: Mounted root (yaffs2 filesystem) readonly.                                 
Freeing unused kernel memory: 120k freed                                       
Please be patient, while OpenWrt loads ...                                     
Failed to execute /etc/preinit.  Attempting defaults...                         
Kernel panic - not syncing: No init found.  Try passing init= option to kernel.

I'm kind of at a loss here, but I suspect the bootloader (or the kernel?) needs to be told where the root filesystem can be found?

Also kind of think something should go in /boot - but not sure what.

Any and all pointers greatly appreciated. :-)

Thanks.

setup type 27 partition on cf card for linux kernel

did "dd if=openwrt-rb532-vmliux of=/dev/sdc1" (my build box cf card slot = sdc)

setup type 83 partition on cf card for linux filesystem.

unpacked openwrt-rb532-2.6-rootfs.tgz into a directory on build box, and did cp -rp <all directories in unpacked rootfs> /dev/sdc2

put cf card in rb532, powered up and get:

Failed to execute /etc/preinit.  Attempting defaults...                         
Kernel panic - not syncing: No init found.  Try passing init= option to kernel.

I haven't tried OpenWrt on an rb532, so take this with a grain of salt.

The "yaffs" messages seem to imply that the kernel is successfully mounting the rootfs.  Is there an /etc/preinit file in the rootfs?  That's what the kernel is looking for.

This step looks like the problem.  Instead of doing this, do as follows:

Make sure you have yaffs compiled into the kernel on your desktop.
mount /dev/sdc2 /mnt
cd /mnt
tar xzvf /path/to/openwrt-rb532-2.6-rootfs.tgz
cd /
umount /mnt

Then try booting the board again.

Wodin,

Thanks for suggestion, but no joy. There is /etc/preinit, it IS executable. I even went so far as to change line 1 of that script to "#!/bin/sh -x" (assuming the -x flag works the same as for csh, ksh, bash, etc. and turns trace/debug on for the script) just to see if the script is getting launched and failing or just not executing at all.

Since output is same, I assume the kernel can't find my rootfs, but it knows what to look for...

Any other ideas?

-d-

have tried Wodin's suggestion of unpacking rootfs tarball directly on CF instead of copy. No joy.

have tried making /dev/cfa2 bootable via fdisk flag. No joy.

have tried:

echo root=/dev/cfa2 > kernel.params
echo init=/bin/sh >> kernel.params
mipsel-linux-objcopy --add-section kernparms=kernel.params

No Joy.

Any other suggestions / links to howto's that DON'T involve netbooting?

Thanks,

-drew-

Here is a HowTo.

try to dd a full jffs2 image:

dd if=openwrt-rb532-jffs2-128k.bin of=/dev/sdc

Well now don't I feel silly.

After I did:

dd if=openwrt-rb532-jffs2-128k.bin of=/dev/sdc

I did:

cfdisk /dev/sdc, just to see what things looked like, and noticed the /dev/sdc1 had the boot flag set.

I went back to another CF disk I had, with a vmlinux on it that I'd compiled yesterday, and set the boot flag on 1st partition, and what do you know...a bootable linux.

But that's not why I feel silly. In my frustration, I'd decided that starting from scratch was the thing to do, so I deleted my old kamikaze svn tree and checked it out again.

In doing so, I lost all progress on souce code downloads, and I'm trying to build a "proper" kernel today...as luck would have it, none of the mirrors are letting me have the openssl-0.9.8e.tar.gz, so I either have to wait, or maybe some kind soul will post it on a website like they did yesterday with the dtc sources...

(please?)

Thanks all for the moral support through this bit of operator error...I was setting the bootflag on 2nd partition, not first.

-drew-

This works for me:
http://www.openssl.org/source/openssl-0.9.8e.tar.gz

By the way, there's an option in menuconfig to point at a different dl directory.  If you keep the dl directory separate from your trunk checkout you can wipe the checkout without losing the downloaded source tarballs.

Also, in theory, "make distclean" should be the same as removing and checking out again and saves a bit of bandwidth.

Good to know Wodin (make distclean). Thanks.

Yes - grabbing it by hand worked fine for me as well. For whatever reason, ALL of the repositories of just the openssl sources were non-responsive to wgets, but openssl.org worked fine 'manually'...go figure. I just assumed I had same problem as with the dtc sources yesterday.

So now I've got a bootable vmlinux - which boots into a <virtual?> root filesystem.

I've done the unpacking of the rootfs tarball on my second partition, and setup an /etc/fstab in the "builtin" rootfs that's available on booting the kernel...for some reason (ignorance I'm sure) I'm not able to mount the / on /dev/cfa2 - any ideas?

I have done the kernparm thing with root=/dev/cfa2 and mipsel-linux-objcopy, and this appears as a kernel command line option at boot time.

So how do I 'get rid of' the tiny little rootfs that lives in the first petition (or is it in NAND?) and "trade up" to the nice full-featured one on /dev/cfa2?

Thanks to anyone for help with this bit!

-drew-

I would mount the cf under openwrt.
Openwrt boots pretty well. I installed the rootfs and the image on the cf and then load into memory.
But at linux shell, there is no way to mount the cf.
I would use it to store modify data.
Regards

It is very strange that nobody reply to my question.
Is it to trivial? Or this forum has been closed?
G

Do you mean that OpenWrt boots from the cf?

What do you mean by "and then load into memory"?

Why not?  How did you try?  What happened when you tried?

Does something like this not work:

mount /dev/cfa2 /mnt

Well, initially I put the image and the rootfs on the flash card, along with the script to load them into the flash chip on board.
Now I am doing all from tftp.
Then
1) I download the image and the rootfs via tftp at boot time (Redboot), and I created correctly the two partition (kernel and rootfs)
1') I load the image and the roots into the flash chip on board. And then go -n xxxxxxx
2) I see the prompt from OpenWRT
3) I cannot see any cfa2 device in /dev

So, what I am missing?

My objective is
1) At very first boot, let RedBoot download the image and the rootfs. Create the partition into the flash chips and load the image and the rootfs into the partitions.
2) Since at the next reboot, I have not to re-create the partiotions (otherwise I will lose data), I would create a script into the flash card which only load the image and the rootfs into memory. Is it right?

Any reply will really very appreciated

can you post the results of a:

cat /proc/mtd

root@OpenWrt:/# cat /proc/mtd
dev:    size   erasesize  name
mtd0: 00060000 00020000 "RedBoot"

mtd5: 00001000 00020000 "RedBoot config"
root@OpenWrt:/#

also paste the output of:

cat /proc/version

you may want to try your luck with one of the following images here

Linux version 2.6.21.6 (nbd@ds10) (gcc version 4.1.2) #2 Sun Sep 30 20:44:34 CEST 2007

here is the output of the /proc/mtd using the above image and a cf on a RB532a:

cat /proc/mtd

dev:    size   erasesize  name
mtd0: 01020000 00020000 "/dev/cfa2"
mtd1: 00400000 00020000 "Routerboard NAND boot"
mtd2: 07c00000 00020000 "rootfs"

Sorry for my elementary questions, but which image should I load?
By far, I used squashfs and a rootfs image.
G

you can use this one and:

dd if=openwrt-rb532-jffs2-128k.bin of=/dev/cd-device
