Dual boot with Openwrt on NAND

Dual boot with Openwrt on NAND
April 02, 2018 05:10AM
Hello,

I installed Openwrt on my Dockstar on the nand memory accordung to this tutorial:
https://wiki.openwrt.org/toh/seagate/dockstar
I used the single stage uboot installation and now I have the following uboot version:
U-Boot 2014.10 (Jan 02 2016 - 02:33:53)Seagate FreeAgent DockStar
SoC:   Kirkwood 88F6281_A0
DRAM:  128 MiB
WARNING: Caches not enabled
NAND:  256 MiB
In:    serial
Out:   serial
Err:   serial
Net:   egiga0
88E1116 Initialized on egiga0
Openwrt is running fine, but I wanted to use it as dual boot system, i.e. when there is a USB stick inserted, it should boot it, but is does not.
Can anybody please tell me what I have to configure at the console to enable it?
(I have a serial console available)
Is there a tutorial to prepare the USB system? I am not sure if my old one is corrupted.

Kind Regards, Dieter

I don't see, that uboot is checking any USB drives. (But I am obviously no expert)

What is in the USB drive? Debian, OpenWrt?

Thanks!

It is Debian.

As I said, I am nicht sure if it is ok. I would generate a new one, if I knew how.

I have several linux systems running, but no other Dockstar.

Somewhere in this Rescue subforum there was a post that showed how to boot Debian with OpenWrt u-boot.

But if you flashed my released u-boot, you can also boot both OpenWrt and Debian.

Hi bodhi,

thanks for your support.
Ok, I will try to flash your u-boot tonight. Will the boot paremeters of Openwrt remain the same as before? Or how do I ensure, that my Openwrt will boot again?

Re: Dual boot with Openwrt on NAND

Hi bodhi,

I am a bit scared to update uboot, because my mtd sizes look very different:

root@OpenWrt-Dockstar:/tmp/tools# cat /proc/mtd
dev:    size   erasesize  name
mtd0: 000e0000 00020000 "uboot"
mtd1: 00020000 00020000 "uboot_env"
mtd2: 00100000 00020000 "second_stage_uboot"
mtd3: 0fe00000 00020000 "root"

Specially, the size of mtd0 does not fit. Can I still upgrade? What have I got to consider?

If I update, should I use the default uboot.2016.05-tld-1.environment.bodhi.tar, too?

What do I have to set to boot my openwrt again?

Thanks again for your support!!

Regards, Dieter

Dieter,

You're right to be careful. You should not upgrade u-boot without knowing that it still boots OpenWrt.

> Specially, the size of mtd0 does not fit. Can I
> still upgrade?

No, you can't upgrade u-boot just yet.

> What have I got to consider?

If you are willing to reinstall OpenWrt/LEDE then see joerg's howto here:
https://forum.doozan.com/read.php?4,42279

The Dockstar has its own images at that download site.

Hi bodhi,

I am trying to update uboot, now, but flash_erase is not working:
root@OpenWrt-Dockstar:/tmp/tools# ls
busybox        flash_erase    fw_printenv    nandwrite
e2fsck         fw_env.config  nanddump
root@OpenWrt-Dockstar:/tmp/tools# ./flash_erase  /dev/mtd0 0 4
/bin/ash: ./flash_erase: not found
root@OpenWrt-Dockstar:/tmp/tools# /tmp/tools/flash_erase  /dev/mtd0 0 4
/bin/ash: /tmp/tools/flash_erase: not found
root@OpenWrt-Dockstar:/tmp/tools#

Very strange, because fw_printenv works.

Any idea what is going wrong?

Couldn't I do it via serial as for the openwrt:
mw 0x800000 0xffff 0x80000
tftpboot uboot.2017.07-tld-1.dockstar.mtd0.kwb
nand erase 0x000000 0x100000
nand write.e 0x800000 0x000000 0x80000
setenv bootcmd nand read.e 0x2000000 0x100000 0x400000\; go 0x2000000
saveenv

Probably need to adjust the addresses, right?
How about the envs I have to set afterwards?

Dieter ,

Try using the OpenWrt flash_erase.

----

If you flash it in serial console, you also need to flash the default envs image too. Or you can also use a script I had posted to populate the envs.

Hello bodhi,

I tried, and still get the same message:
root@OpenWrt-Dockstar:/tmp# /usr/sbin/flash_erase /dev/mtd0 0 4
/bin/ash: /usr/sbin/flash_erase: not found

So again, I must try it with the serial, I see no other way, do you?

Before I brick my Dockstar, is the input for the serial connection above right, or does it need to be adjusted?
How do I flash the envs?
I currently don't have a booting debian on a stick, so I can not use the script. How do I set up a booting debian image on a stick from scratch?
I can not find the manual to do it.

Sorry to ask so many question, but I am lost right now.

Thank you, Dieter

Dieter,

I am not familiar with OnenWrt so I can't tell why you got this error with flash_erase.

> Before I brick my Dockstar, is the input for the

> be adjusted?

The Dockstar does not have a UART booting recovery. So it is best to flash u-boot inside Debian. Because if the flashing went wrong, there might be still some way for us to fix it. When you flash in serial console, and it is bad then it is bricked! and It is actually easier to flash u-boot if you boot with Debian first.

Create the Debian rootfs Debian-4.12.1-kirkwood-tld-1-rootfs-bodhi.tar.bz2 as instructed in the 1st post:

https://forum.doozan.com/read.php?2,12096

Scroll down to section:

Updated 24 Jul 2017:

Basic Debian stretch Kirkwood rootfs for most Kirwood plugs:

- tarball size: 188M
- install size: 488M
- The init system used in this rootfs is sysvinit . To boot with systemd, see note 2 below.
- Installed packages: nano, avahi, ntp, busybox-syslogd (log to RAM), htop, isc-dhcp-client, dialog, bzip2, nfs server/client, iperf, ethtool, sysvinit-core, sysvinit, and sysvinit-utils.
- see LED controls in /etc/rc.local, and /etc/init.d/halt
- see some useful aliases in /root/.profile
- root password: root

And remember to check the hash of what you download, as always.

Yoiu can create the USB Debian rootfs while in OpenWrt. And reboot. Interrupt serial console and enter some envs to boot from USB. Once you get to that point, if you not sure how to proceed, please post the question.

Hello bodhi,

Thank you for your ongoing excellent support.
I got now this far: I generated my new USB Debian rootfs. But I don't know how to alter the envs to boot from usb.
Could you please, once more, please help me?

Re: Dual boot with Openwrt on NAND

On another Linux box, mount the Debian rootfs that you meant to run on this Dockstar and put the attached u-boot script in the /boot folder (if it was mounted at /media/sdb1):

cp -a uboot.2016.05-tld-1.environment.scr /media/sdb1/boot/

Power up this box and interrupt serial console, run the script loading commands:

usb start
ext2load usb 0:1 0x800000 /boot/uboot.2016.05-tld-1.environment.scr
source 0x800000
printenv

Adjust the other specific envs and then boot the rootfs (replace xx:xx:xx:xx:xx:xx with your real ethaddr):
setenv devices 'usb'
setenv ethaddr xx:xx:xx:xx:xx:xx
setenv dtb_file '/boot/dts/kirkwood-dockstar.dtb'
boot

Once you've booted into Debian, let's pause and take look at your mtd partitions before proceeding to flash new u-boot.

Probably, because the uboot is too old to handle so many arguments per command?

True.

Sure, you did not save anything.

Let me write a few envs. I was hoping I can use the script, but it is too new for this u-boot.

Dear bodhi,

the uboot seems to have problems with your commands:

All the setenvs were fine, but then:
...
dockstar => boot
(Re)start USB...
USB0:   USB EHCI 1.00
scanning bus 0 for devices... 4 USB Device(s) found
       scanning usb for storage devices... 1 Storage Device(s) found
loading uImage ...
Unknown command 'load' - try 'help'
loading uInitrd ...
Unknown command 'load' - try 'help'
loading DTB $dtb_file ...
Unknown command 'load' - try 'help'
bootm - boot application image from memory

Usage:
bootm [addr [arg ...]]
    - boot application image stored in memory
        passing arguments 'arg ...'; when booting a Linux kernel,
        'arg' can be the address of an initrd image
        When booting a Linux kernel which requires a flat device-tree
        a third argument is required which is the address of the
        device-tree blob. To boot that kernel without an initrd image,
        use a '-' for the second argument. If you do not pass a third
        a bd_info struct will be passed instead

For the new multi component uImage format (FIT) addresses
        must be extened to include component or configuration unit name:
        addr:<subimg_uname> - direct component image specification
        addr#<conf_uname>   - configuration specification
        Use iminfo command to get the list of existing component
        images and configurations.

Sub-commands to do part of the bootm sequence.  The sub-commands must be
issued in the order below (it's ok to not issue all sub-commands):
        start [addr [arg ...]]
        loados  - load OS image
        ramdisk - relocate initrd, set env initrd_start/initrd_end
        fdt     - relocate flat device tree
        cmdline - OS specific command line processing/setup
        bdt     - OS specific bd_t processing
        prep    - OS specific prep before relocation or go
        go      - start OS
resetting ...

and here is a working debian.img file (stretch with latest kernel) tested on a dockstar treated like above:
debian image file with kernel 4.16.1 (root/root)

see pictures:
LEDE booting
ready for debian booting

good luck

Ah. I forgot the load commands. Try

setenv bootdev usb
setenv device 0:1
setenv set_bootargs 'setenv bootargs console=ttyS0,115200 root=LABEL=rootfs rootdelay=10 earlyprintk=serial'
setenv load_dtb_addr 0x1c00000
setenv load_initrd_addr 0x1100000
setenv load_uimage_addr 0x800000
setenv dtb_file '/boot/dts/kirkwood-dockstar.dtb'
setenv load_dtb 'echo loading DTB $dtb_file ...; ext2load $bootdev $device $load_dtb_addr $dtb_file'
setenv load_initrd 'echo loading uInitrd ...; ext2load $bootdev $device $load_initrd_addr /boot/uInitrd'
setenv load_uimage 'echo loading uImage ...; ext2load $bootdev $device $load_uimage_addr /boot/uImage'
setenv bootcmd_exec 'run load_uimage; run load_initrd; run load_dtb; bootm $load_uimage_addr $load_initrd_addr $load_dtb_addr'
setenv bootcmd 'usb reset; run set_bootargs; run bootcmd_exec; reset'

and then

boot

Hello both of you,

First of all, thanks again for your support!

I followed joerg's suggestion and I believe I got pretty far.
uboot is updated and so on.
I booted lede, but the opkg installation failed:

It seems, I am running out of file space.
Please, what can I do?

Is something wrong with my mtd?
Here is it:
root@LEDE:/# cat /proc/mtd

These are my boot message, there is an UBI Error:

Re: Dual boot with Openwrt on NAND
April 22, 2018 04:41AM
yes dieter i have changed the mtds because you dont need now a second stage bootloader and a seperate definition for the boot-envs
so you have the fully nand for pakets in LEDE and never run out of space.
I have defined the mtds only for:
bootloader + envs starting at 0x0 size 0x100000
LEDE starting at 0x100000 size <till the end of nand>
you should only define your mtds like this:
# @bootloader

setenv mtdparts 'mtdparts=orion_nand:0x100000@0x0(u-boot),-@0x100000(ubi)'
saveenv

# Attention, dont forget to nand erase your new mtd "ubi" before you flash LEDE on it.
nand erase.part ubi
you should do the paket installation after
DockStar> usb reset; fatload usb 0 0x800000 lede-kirkwood-dockstar-initramfs-uImage; bootm 0x800000
to install pakets before its not necessary anymore because you do your sysupgrade from LEDE-WIF and not from CLI.

Hello,

ok, system upgrade worked, I am able to run LEDE now. :-)
However, it seems my envs are not fine, yet, I can not boot from stick.
I inserted a stick, prepared as bodhi told me to, but Lede still boots and I get the following error messages:

I am afraid to mix setting up, so could finally some tell me what I have to set now to be able to dual boot?

Once again, thank you for your support, both of you!

Re: Dual boot with Openwrt on NAND
April 22, 2018 01:01PM
hello dieter, you are right, this are the old envs.
maybe i forgot to tell you
you have to restart the dockstar once after flashing uboot in nand and interrupt start again
reset
than you can tftp boot the new envs and fllash them in nand.
than do the rest of modification for uboot-envs for your dockstar like in my discription above:
setenv ethaddr <ethaddr Userbox>
setenv arcNumber 2998
setenv machid
setenv dtb_file '/boot/dts/kirkwood-dockstar.dtb'
saveenv
reset

Hallo dieter
in this part you got an error you forgot to put "setenv" befor see here:
DockStar> setenv mtdparts 'mtdparts=orion_nand:0x100000@0x0(u-boot),-@0x100000(ubi)'
DockStar> setenv set_bootargs_lede 'setenv bootargs console=ttyS0,115200 $mtdparts'
DockStar> setenv bootcmd_lede 'run set_bootargs_lede; ubi part ubi; ubi read 0x800000 kernel; bootm 0x800000'
DockStar> setenv bootcmd 'run bootcmd_uenv; run scan_disk; run set_bootargs; run bootcmd_exec; run bootcmd_lede'
DockStar> bootcmd_exec 'if run load_uimage; then; if run load_initrd; then if run load_dtb; then bootm $load_uimage_addr $load_initrd_addr $load_dtb_addr; else bootm $load_uimage_addr $load_initrd_addr; fi; else if run load_dtb; then bootm $load_uimage_addr - $load_dtb_addr; else bootm $load_uimage_addr; fi; fi; fi'
Unknown command 'bootcmd_exec' - try 'help'
DockStar> saveenv
Saving Environment to NAND...
Erasing NAND...
Erasing at 0xc0000 -- 100% complete.

DockStar> reset
resetting ...
the right command should be:
setenv bootcmd_exec 'if run load_uimage; then; if run load_initrd; then if run load_dtb; then bootm $load_uimage_addr $load_initrd_addr $load_dtb_addr; else bootm $load_uimage_addr $load_initrd_addr; fi; else if run load_dtb; then bootm $load_uimage_addr - $load_dtb_addr; else bootm $load_uimage_addr; fi; fi; fi'
and everthing should be fine.
