Back again :) I tried to do an upgrade of my 4.12.1-kirkwood to 4.15.2-kirkwood. But it does not boot up. I think it get stuck at U-boot, and I just realized that my USB-serial adapter is probably at home as can't find it anywhere here. So I can't see what it is doing until tomorrow. But what would you guess I did wrong?

I did it like this:

ROOTFS
1. I find the latest kernel at https://forum.doozan.com/read.php?2,12096,12096#msg-12096

2. Download the file

cd /boot
wget https://bitly.com/2EksnWU
mv 2EksnWU linux-4.15.2-kirkwood-tld-1-bodhi.tar.bz2

3. Backup files

cd /boot
mkdir backup/2018-03-12
cp uInitrd backup/2018-03-12
cp uImage backup/2018-03-12
cp initrd.img-4.12.1-kirkwood-tld-1 backup/2018-03-12
cp System.map-4.12.1-kirkwood-tld-1 backup/2018-03-12
cp vmlinuz-4.12.1-kirkwood-tld-1 backup/2018-03-12
cp config-4.12.1-kirkwood-tld-1 backup/2018-03-12
cp dts/ backup/2018-03-12/dts -r

4. Extract the kernel and the DTB files in the archive

cd /boot
tar -xjf linux-4.15.2-kirkwood-tld-1-bodhi.tar.bz2
tar -xf  linux-dtb-4.15.2-kirkwood-tld-1.tar

5. And install it with dpkg

cd /boot
apt-get remove flash-kernel 
dpkg -i linux-image-4.15.2-kirkwood-tld-1_1.0_armel.deb

It say:

6. Boot with DTB file embedded in the kernel image

cd /boot
mv uImage uImage.orig
cp -a zImage-4.15.2-kirkwood-tld-1 zImage.fdt
cat dts/kirkwood-goflexnet.dtb >> zImage.fdt
mkimage -A arm -O linux -T kernel -C none -a 0x00008000 -e 0x00008000 -n Linux-4.15.2-kirkwood-tld-1 -d zImage.fdt uImage

It say

I run

mkimage -A arm -O linux -T ramdisk -C gzip -a 0x00000000 -e 0x00000000 -n initramfs-4.15.2-kirkwood-tld-1 -d initrd.img-4.15.2-kirkwood-tld-1 uInitrd

It say:

7. The new uImage and uInitrd files should be created in /boot directory now. You're ready to reboot the system:

sync

sync
shutdown -r now

The DTB file name is wrong. Should be n1t1.

The rest looks OK.

Wow, you have good eyes! It would have taken me a long time before I had seen that. THANKS!

1. Booted up with USB

2. Login with root root and did this just in case

su -

3. Connect to hdd / and Go to hdd boot

mount /dev/sda1 /mnt/start
cd /mnt/start/boot

4. Try to fix my mistake

cat dts/kirkwood-n1t1.dtb >> zImage.fdt

5. Reboot

shutdown -r now

6. It still don't boot up. See attached file

7. So I try to boot with USB again and restore backup

su -
mount /dev/sda1 /mnt/start
cd /mnt/start/boot
cp backup/2018-03-12/uInitrd .
cp backup/2018-03-12/uImage .
cp backup/2018-03-12/initrd.img-4.12.1-kirkwood-tld-1 .
cp backup/2018-03-12/System.map-4.12.1-kirkwood-tld-1 .
cp backup/2018-03-12/vmlinuz-4.12.1-kirkwood-tld-1 .
cp backup/2018-03-12/config-4.12.1-kirkwood-tld-1 .
cp backup/2018-03-12/dts dts/ -r
sync

Now it boot up again with the hdd :-)

Cool!

But too bad you've replaced the 2 new kernel files. We need to look at those files and the boot log at the same time to see clues why it did not boot. Please recreate them,

cd /boot
cp -a uImage uInitrd ./backup/2018-03-12/
mkimage -A arm -O linux -T kernel -C none -a 0x00008000 -e 0x00008000 -n Linux-4.15.2-kirkwood-tld-1 -d vmlinuz-4.15.2-kirkwood-tld-1 uImage 
mkimage -A arm -O linux -T ramdisk -C gzip -a 0x00000000 -e 0x00000000 -n initramfs-4.15.2-kirkwood-tld-1 -d initrd.img-4.15.2-kirkwood-tld-1 uInitrd

Boot again, see if it boots. If not, before going back to old kernel, you should get the listing before replacing.

mount /dev/sda1 /mnt/start
cd /mnt/start/boot
ls -lart *
ls -larth *

BTW, always use the cp option -a to copy files, so you can preserve the time stamps and all other attributes.

Thanks for the cp option -a info! OK, here is my test log.

I start with

cd /boot
cp -a uImage uInitrd ./backup/2018-03-12/

I try "Boot with DTB file" as you suggest in the post

Boots up with the hdd.

raffe,

You misread the instruction. Booting with separate DTB is recommended only when you are running the new uboot that I released (there is no new LG N1T1 uboot yet).

Quote

I try "Boot with DTB file" as you suggest in the post

With stock uboot, you must boot with embedded DTB.


And you dont really know how to post the log for trouble shooting purpose :) You have posted info in a really nice and organized way. But that has made the “debugging” harder.

What I’d like to see is one log in code tags, with no need for commentary, commands you actually typed and all of the outputs from that. From installing kernel to the power up, to boot failure. Usually, you just copy and paste the whole terminal session.

But it is ok this time. I will take a look.

You need to adjust u-boot envs to do that.

In Debian, get the output of

cat /etc/fw_env.config
fw_printenv

and post here.

Please post the serial boot log that shows how you run u-boot envs to boot the new kernel on USB. I only need to see from the beggining of u-boot until the first part of kernel booting that inlcude the kernel command line.

And you can post the log here in code tags (It is easier to read/search than log on another text file).

Do this with USB rootfs attached. It should boot to Debian.

Power up, interrupt seriall console and

setenv bootargs_usb 'console=ttyS0,115200 root=LABEL=rootfs rootdelay=10 mtdparts=spi_flash:0x78000@0(uboot),0x1000@0x78000(env) earlyprintk=serial'

setenv bootcmd 'run bootargs_usb; run bootcmd_usb; run bootcmd_hdd'

And then repeat without USB rootfs. It should boot to stock HDD.

I am a noob when it comes to linux so just to clarify, I enter it all at once as one command?

Only your first line is correct, every line after that is corrupted and does not match what you were asked to enter. How did you enter the commands?

You should enter each line from bodhi's post 1 line at a time.

Hello, I do not know if this topic has any kind of comment from all those who have commented here but I really hope you can help me.

it happens that I have a nas lg N1A1 DD1 that a while ago stopped working because this had the HDD with problems, one day it just started to make a few noises and it did not work but I extracted the HDD since it was already out of warranty and try to replace it with another one but it did not work as I have been reading, I need to install a kind of operating system on the new HDD and I have no idea how to do it.

I do not have much experience in Linux or anything like that, I just need to know how to install the software I had in the simplest way possible and I saw that according to another forum it could be done from a USB with the original files of LG but the latter in its platform do not say what steps to follow in case the HDD is broken so it seems that they believed they would be eternal.

I hope you can help me with this issue I am sorry to ask now but it is that my NAS worked without problems until couple of months ago that at the moment I stop working without giving me time to do backup or anything.

Roca,

Ron did get this box working, so it will not be too difficult.

Do you have serial console connected? if not, can you do that (open the box), buy parts and wire?

Look at how people do this in the Wiki thread. In particular the post I highlighted below.

Since we don't have new u-boot for this box, installation is so that you can run the latest Debian rootfs from this release thread: Debian-4.12.1-kirkwood-tld-1-rootfs-bodhi.tar.bz2 .

So to sum up the general steps:

1. Create the new rootfs on USB using the tarball Debian-4.12.1-kirkwood-tld-1-rootfs-bodhi.tar.bz2, following the instruction in that release thread.
2. Connect serial console.
3. And set some envs in u-boot to boot with the new USB rootfs.

hello bodhi thank you for your prompt response if I tell you that I understood everything you said I would be lying really this complicated thing as I mentioned I have no experience in this kind of technical stuff ... my question is: it is not possible from a USB mount the image of the original operating system of the NAS as if it were a windows installation without much complication?

That would be more complicate than installing a new system.

Unless you could find a rescue USB image from the manufacterer.

A lot of NAS have some kind of restore mechanism with USB, where you would prepare a USB drive using their rescue image. And using a procedure provided by them to reinstall the stock FW on your NAS.

Perhaps you could browse their website to see if you can find that USB image for reinstallation.

Hi.

I do not expect more people to come for information on this old thread, but it seems the best to tell about my experience and give feedback.
First, let me thank you for all that astounding work. I could not believe that one could run a recent Debian on such a machine, very limited in resources.

I got a used N1T1DD1 some years ago but did not find too much use to it, the 1 Gb disk being a bit tight for my needs. I had a 3 Gb disk just ordered and replaced the original one. It got formatted as MBR by the stock software, version 2452.340 as I noted. The disk was seen only as 2 Gb because of MBR limit, I did not go further at that time.
I needed a storage device recently and dug it out, managed to upgrade Uboot, the drive was formatted as 3 Gb to my pleasure. I managed with the help of raffe's detailed explanations (what I sorely needed) to boot once to Debian connected through usb serial adapter. All further attempts failed after "usb start".

History (i'll cut the failed attempts) :
- initialized the box, version 2452.340
- upgraded Uboot with new_ui_uboot_update_111223
- installed latest firmware-N1T1_10124rfke modified to get root access (modifying postinst.sh). The disk
was reformatted but this time as hybrid MBR/GPT.
- root access failed but user lgroot was created, but following a post on www.geeek.org about gaining root
access through a hidden page allowed me get in through telnet
- I had to modify the apt sources, the address on the US site no longer responded, installed dropbear and
was able to ssh into the nas.
- after the failed attempts at booting debian, I had the idea of formatting the usb stick with the nas, and
then doing all the stuff through my Mint box. It works better but still many reset to do.

I am in the process of installing a dual boot, now, and wish to thank you all. My goal is to install a nextcloud server on it, for shared work at home, and I may possibly be happy with a permanent installation of Debian on the main disk. If you have suggestions, warnings, please tell me.

If you are going to run nextcould then the Debian rootfs should be on the HDD.

Thanks for the answer, I would never think about keeping the root directory on external usb stick, except maybe for testing. I still have to understand how to install and run from the partition which contains the "main" OS, meaning deleting it. Hybrid MBR/GPT is still beyond my knowledge and , if I understand properly, there is no way grub can work like on standard PC. Can the rootfs just be copied to the first partition of the disk ? I noticed that without information about the usb rootfs, booting takes that partition as root.
Last question, if it is the case, would it work "as is" without modifying the environment variables (which I doubt) ?

Regards.

Correct. All ARM boxes like this one use u-boot, not Grub. And I would avoid Hybrid MBR/GPT if you can live with multiple 2-TB-or-less partitions. OTOH, a lot of people found that they are using Hybrid successfully, so it's your choice.

Yes. What you can do is a simple procedure to tar the USB rootfs to a tarball, and then restore it on the HDD with an empty Ext3 parttion.

As described in the Wiki thread:

You need to modify u-boot envs to boot with SATA. When you are ready, I will help with that. Connect serial console and we'll change a few envs to boot to HDD rootfs. After it works for a few reboot, then we'll save the envs permanently.

Hi bodhi.

It turned out to quite easy. printenv gave me all the pointers to solve this little problem.
I did it so :

- tar'ed the original file system and saved it on my PC

- deleted all the files/directories and untar'ed the Debian file system at the same place.

- saved the original environment on my PC

- modified bootcmd_hdd from
bootcmd_hdd=run read-kern; setenv bootargs $(console) $(root_path) lpj=4964352; bootm 0x2000000;
to
bootcmd_hdd=run ide reset;ext2load ide 0 0x800000 /boot/uImage;ext2load ide 0 0x2100000 /boot/uInitrd;bootm 0x800000 0x2100000
by doing :
setenv bootcmd_hdd 'ide reset;ext2load ide 0 0x800000 /boot/uImage;ext2load ide 0 0x2100000 /boot/uInitrd;bootm 0x800000 0x2100000'

- typed "run bootcmd_hdd", enter, and booted from hard disk. That file is the one run at boot I think.

ide reset is necessary; if not run the disk is not detected.
setting mainlineLinux to yes is unnecessary.
I will make the changes permanent, as I backed up the environment, it will be easy to go back.
I will keep all updated. Thanks

EDIT :
It worked perfectly. If one needs to go back to the previous configuration, it is quite easy to unset a variable (setenv xyz without argument) ou just overwrtite it.
Second point, the trouble with usb stick went away (for most of them, except the weirdest ones) but running
usb reset
instead of
usb start
It gave me a consistent behavior, it seems to be very reliable.

Third point, I checked for the latest Uboot files, but the n1t1 is not listed, too old or too few requests ?

Jmax,

Yes. Not a lot of users have this box, so I did not build new u-boot for it. Testing is time consuming so unless I have a lot free time, I don't try to start the project.
