Rooting Toon (or boxx)

[djxfma]

@marcelr Really apriciate the help!

I can't download the file from: http://files.domoticaforum.eu/uploads/T ... uImage-nfs[/b]
Because the server gives acces from only known extensions, could you put .txt after it or .zip.

Gonna give it a go after I can download the kernel !

[marcelr]

OK, done. Just chop .zip off the name and you're good to go.

[djxfma]

So I got the tftpboot to work, but I got this error message will search some stuff up see if can that fixed, maybe I need to assign the address for kernel or something?

Code: Select all

[marcelr]

The image I uploaded is 2503412 bytes in size. Maybe your download settings were wrong (ASCII mode?)

To boot, you need to do a lot more than just run bootm.
Will upload an example tonight.

[djxfma]

Update
Ok I did it xD, it was because of the NFS version was not given with the mounting options true the bootargs.
I changed the commands below to the right ones.

Commands I used to get boot to work, and trying to mount rootfs:

Code: Select all

dhcp
setenv serverip 192.168.5.199
setenv autoload no
setenv bootfile toon/uImage-nfs
setenv bootargs console=${console},${baudrate} rootwait root=/dev/nfs nfsroot=192.168.5.199:/srv/tftpboot/toon/rootfs,v3,tcp,nolock rw ip=dhcp

tftpboot 0xA1000000 toon/uImage-nfs
run bootargs; nand read ${loadaddr} kernel; bootm ${loadaddr}

Exports list of the NFS server:

Code: Select all

/srv/tftpboot/toon/rootfs    *(rw,sync,no_root_squash,no_subtree_check)
/srv/tftpboot/toon           *(rw,sync,no_root_squash,no_subtree_check)

[marcelr]

So it's working now?

[djxfma]

So it's working now?

Well the booting went fine, but now little bit stuck on the attaching of ubi.
So then I saw that I completely missed the code already provided by the tutorial..
But still can't seem to get the /dev/mtd4 to work, as well it does not exists at /dev location.'
But it does say it is attached to ubi0 device, already searching some google, but till now did
not find the right magic.

This is the terminal in/output:

I don't think you're booting the right kernel:

Code: Select all

...
## Booting kernel from Legacy Image at a1000000 ...
   Image Name:   Linux-2.6.36-R10-h27
...

That's the native kernel on toon, not the nfs-supporting version that I uploaded.

You don't need the step

Code: Select all

nand read ${loadaddr} kernel

bootm will do.

After booting of the kernel, you fall back to /bin/sh, so there's no operating system present, it's just the kernel that's up and running.
From the bootlog it appears that a rootfs is mounted, but init isn't started properly.

If you do

Code: Select all

printenv

While in u-boot, do you still have the init=/bin/sh somewhere in the u-boot environment?

[djxfma]

Oh daymn.. that makes sense tho. When if I leave out that command line it will not boot at all.
Before you said something about the kernel was downloaded ASCII mode I copied true samba,
but also tried from my RPi straight with: wget, and after I taught off loading the uboot tftpboot
uploaded kernel by forcing it to see it. But proberly not the way to go.

Stuck at kernel bad CRC when not using the nand commandline.

OK. I uploaded the kernel image again. Properly zipped this time.
Download, unzip and try again, if you want.

Try and skip this one:

Code: Select all

setenv bootargs ubi.mtd=4

Some toons have a flash layout that's not standard, which results in this error:

Code: Select all

UBI error: validate_ec_hdr: bad VID header offset 2048, expected 512
UBI error: validate_ec_hdr: bad EC header
UBI error: ubi_io_read_ec_hdr: validation failed for PEB 0

You can attach the ubi later on, manually, using ubiattach. See my post, from a few days ago.

Bin a few day's I could not get it to work, the ubbiattach all the time there was no ubi device or something allong that line.
But I looked back at the log file and googled for some time understanding the way how ubi works and reading from nand.
And errors it gave, in screen before posted it already is showing the error, that the VID Header was 512 some how when it tried to mounting the mtd4 with the attaching of ubi. There is an simple fix for it and its using ubi.mtd=4,2048 so it will take that VID header and apply it at mounting and reading it from NAND.

After the command provided with /dev/ubi0:rootfs did not worked, and was telling that the argument was not right, so found out that it should be ubi0:rootfs instead of /dev/ubi0:rootfs. So with the code below I got in, and got the rootfs mounted, then I went in first because chroot did not work, because the busybox did not had any execution permissions xD lel.. so fixed that with a simple chmod +x /mnt/rootfs/bin/busybox.

U-Boot:

Code: Select all

dhcp
setenv serverip 192.168.5.199
tftpboot 0xa1000000 toon/uImage-nfs
setenv bootargs ubi.mtd=4,2048
setenv bootargs ${bootargs} root=/dev/nfs rw nfsroot=192.168.5.199:/srv/tftpboot/toon/rootfs,v3,nolock,tcp console=ttymxc0,115200 loglevel=8
setenv bootargs ${bootargs} mtdparts=mxc_nand:512K@0x00100000(u-boot-env)ro,1536K(splash-image),3M(kernel),3M(kernel-backup),119M(rootfs)
setenv bootargs ${bootargs} ip=192.168.5.198:192.168.5.199:192.168.5.199:255.255.255.0:toon::off
bootm

Bash:

Code: Select all

mount -a
cat /proc/devices | grep ubi0
mknod /dev/ubi0 c 252 0
mkdir /mnt/rootfs
mount -t ubifs ubi0:rootfs /mnt/rootfs
chmod +x /mnt/rootfs/bin/busybox
chroot /mnt/rootfs

Now gonna do the install of the opkg's xD
Thanks for all the help!! Learned a lot from this lel.

Great job! This should be in the manual section as a new topic 'how to boot a possible bricked toon from tftp/nfs'

[marcelr]

It's all here:
viewtopic.php?f=87&t=8743&hilit=dead+as ... 270#p79224
Will add the mount/chroot bits and copy it to the manuals section. Job for the weekend.
