[STORA] New rootfs installation

Hello here,

I'm a new user of this forum, i'm navigate easily in Linux but beginning in "kernel/rootfs/boot" idea.

I have follow this topic to unbrike à Netgear Stora MS2110 with poor stock version :
https://sigri44.github.io/OpenStora/wiki/index_How_to_install_Debian_Linux_on_NETGEAR_Stora.html

I can only have GPIO/Serial access (with ardruino + TTY), and i don't understand how to replace uBoot/rootfs, to have a recent access.

The topic i follow can give me a Stretch installation, but in repository step, it's failed because version is very deprecated.

In follow my hardware logs :
https://gist.github.com/Sigri44/3903ef9233b7125003ff45762a513613

And my installation logs :
https://gist.github.com/Sigri44/ccea2a11082fc1d55f1829d906f99d3b

I don't know what is my "uBoot" version, and i don't understand how to follow this installation topic :
https://forum.doozan.com/read.php?2,12096

Have fun !

Sigri,

1. Create the USB Debian rootfs using Debian-5.13.6-kirkwood-tld-1-rootfs-bodhi.tar.bz2

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

2. Dowload the u-boot tarball uboot.2017.07-tld-1.netgear_ms2110.bodhi.tar to this new USB rootfs:

https://forum.doozan.com/read.php?3,12381

3. Before flashing new u-boot, you need to use kwboot to run the new u-boot image over UART, to make sure you can recover from a bad flash.

Read those 3 instructions, make sure you understand all before installation. If you don't understand something, post the question.

Hey, thank you for reply !

Step 1 is done. Now in step two, i don't undestand how to unzip the *.kwb file to the /boot folder.

For the moment rootfs key is on my computer and not on NAS, and i don't know how to install/unzip this file into boot, because tuto use flashing method, or /rootfs method but need printenv, etc, and i think this command is only on the NAS.

Thx.

EDIT : FYI, actual uboot version :
https://gist.github.com/Sigri44/dee6f2099f53eac888ac0f6a9311b780

EDIT2 :

./kwboot -t -B 115200 /dev/ttyUSB0 -b uboot.2017.07-tld-1.netgear_ms2110.mtd0.kwb

Result is

Sending boot message. Please reboot the target.../

But after rebooting, and press stop button to don't launch OS, no any result.

And if i don't press stop button, launch failed because usb boot don't find uImage and start is crashed.

I try another method.

Step 1 > Done, apply netgear kirkwood image

Step 2 > All tutos say "use cat command", but only available if you boot into Debian OS. Btw you specify to copy uboot file INTO usb stick, but don't understand how to realize it ?

Bonus : I have see in another topic, usb stick is always need, but have you a topic to write debian os into flash memory, and don't need usb stick to boot in the future ?

Thank you.

Sigri,

> Step 1 > Done, apply netgear kirkwood image

You need to follow the instruction very closely. The USB rootfs must be created on a Linux box (such as Ubuntu, Raspery PI...), with you being root user. The rootfs you created is not good.

It can be done on any Linux box.

Use wget to download to some folder on the USB rootfs. For example, /boot folder.

====

Post the log of the session how you created the rootfs here (copy everything on the terminal and paste here).

Thank you Bodhi,

I already make Step1 with Kali root terminal

cd /media/root
tar -xjf Debian-5.13.6-kirkwood-tld-1-rootfs-bodhi.tar.bz2
mv /media/root/rootfs/* /media/root/

nano /media/root/etc/fstab
LABEL=rootfs    /               ext3    noatime,errors=remount-ro 0 1

cd /media/root/boot
cp -a zImage-5.13.6-kirkwood-tld-1  zImage.fdt
cat dts/kirkwood-netgear_stora_ms2000.dtb  >> zImage.fdt
mv uImage uImage.orig
apt-get install u-boot-tools
mkimage -A arm -O linux -T kernel -C none -a 0x00008000 -e 0x00008000 -n Linux-5.13.6-kirkwood-tld-1 -d zImage.fdt  uImage
sync

*I noticed the error that disturbed me, you say to do 'cat /etc/...' but it is 'cat /media/XXX/etc/...'

cat /media/root/etc/fw_env.config
 # MTD device name	Device offset	Env. size	Flash sector size	Number of sectors 
/dev/mtd0 0xc0000 0x20000 0x20000

cat /media/root/proc/mtd
>>>No such file or directory

fw_printenv ethaddr
>>>Configuration file wrong or corrupted

I think this following instruction can't work on my Kali OS, but directly on NAS box with USB stick, right ??

Sigri,

> I already make Step1 with Kali root terminal

It is best that you post the real log of what you've done (not the list of the commands). That way I can spot any errors you've made easily.

Are you root at this point before doing anything further?

who ami

On Kali terminal, to become root:

su -

> cd /media/root
> tar -xjf
> Debian-5.13.6-kirkwood-tld-1-rootfs-bodhi.tar.bz2
> mv /media/root/rootfs/* /media/root/

You should not do the mv command avove.

This below 2 commands only applicable if you are installing from inside stock OS.
