Hi bodhi.

Would the latest u-boot allow booting from a pure gpt system ? I would actually feel better without the hybrid mbr/gpt. Could it allow booting from 2 different gpt partitions whether a usb stick is connected or not (might even be empty, just present) ?
If it is the case, I do have jtag + serial adapter and could do the testing being one month retired with time to spare.

Regards.

Yes, my released Kirkwood u-boots have all those capabilities.

I can't promise that I will build new u-boot for this box. At the moment I'm too busy and don't know when I will have a few-days block of free time.

Please do not worry about that.
I just mentioned being free to build and test it myself if possible, it is more an academic question than anything else.
Do not take the trouble.

Hi bodhi.

I did some more testing after determining that bootrom was version 1.21. kwboot works fine with the first image uboot.2017.07-tld-1.goflexhome.bodhi.tar that mentioned using the same processor, booting proceeds and give me a totally functional debian system.

I am not even sure I need to go any further, the stock N1T1 uboot supports hybrid mbr/gpt, it could as well support plain gpt. I have a spare disk that I shall format gpt, and un'tar the debian, then the stock system. I will update in case somebody comes around.

If I go farther, what should I look for beyond proper disk/net/serial already working ?

I suppose it is a good idea to get the stock uboot backed up and test it with kwboot ?

Regards.

EDIT: I backed up the mtd0 with "nanddump -l 0x80000 -f mtd0 /dev/mtd0" the -n option gives an error. From main PC, I used scp to get the image and tested it with kwboot, works perfectly.

Well done!

No need to if you found that stock u-boot works booting the Debian rootfs.

The GoFlex Home and this N1T1 have the same SoC and memory. But different in other aspect such as flash type, LED GPIOs. Might be the same network chip (I have not looked to confirm but it should be).

So while it is OK to kwboot as a rescue tool, it should not be used as is.

Now you know there is a rescue mechanism working with stock mtd0.

Well, I shouted "victory" too soon.

While installing Linux, I did not understand why the partitions were shown as "linux-raid" and lost any possibility of reverting to the original software. The updated u-boot, which support pure gpt prevents from reinstalling the base software. It is fine with Debian though.
I do not know if anybody still has the original 1Tb box and would be capable of extracting the information I missed at the beginning, some much for my eagerness to get the disk upgraded and not keeping the old one as it was :/

If anybody has the original non-upgraded firmware, I would like to get in touch.

The original firmware can be downloaded from LG's website. As long, the updated u-boot contains LG's rescue mode, it shouldn't be any problem to use it to restore the raid configuration.

Hi S.

I did that already, but it fails. Unfortunately, once updated for the new new U-boot, there is no way back, the original software can no longer be installed, I suppose it relies on the old U-boot. The only solution seems to be reverting to the original U-boot.

The rescue mode will create a raid partition which will require the u-boot to boot the /dev/md0 partition (and not /dev/sda1). So, it might just be wrong configuration. Post your envs and I can compare it with my envs. Otherwise, there exist a uboot file in LG site which can be used to get the old uboot.

Yes, the env variable specify /dev/md0 as the root as root_path.

Some changes were made for Debian, which I tried to revert as
well as possible but, I guess, screwed up something in the process.
I should mention that I tried the rescue process for the new U-boot
system (new UI) but this fails as well. Probably environment being
wrong as you indicate.
In the meantime, I shall search again the LG site to find the u-boot
mentioned.

Regards.

EDIT :
You were right. One single option I overlooked was a "gateway" which
prevented the system from booting. It was straightforward after that, I
was able to restore a full standard system. I just have to figure out how
to fit it with a usb boot for Debian and I will be very happy. Many thanks.

I'm glad it worked out. I have been busy with other things and have almost forgot about the post.
Usb boot should probably be similar steps as described in other posts, haven't tested but it should likely work. Hopefully you will find a solution for it.

Hello N1T1 owners,

I now run my device with Bodhi's Kernel 5.9.12. Finally an open system, thanks for that.

I need help putting this device on standby.
My first attempt with hdparm spoke to the HDD successfully. Unfortunately, it is reactivated after 3 minutes of running processes.
Is it possible to put the device into energy saving mode with this kernel?

Thanks in advance.

If the rootfs is on the HDD, then don't try to put it to sleep. It is not feasible. Only way to ensure the HDD is sleeping all the time is to have the rootfs on USB.

The energy saving mode is possible with this kernel CPU Frequency governor. Install cpufrequtils, and use the cpufreq-set to set the governor to what you like to. There are many modes: userspace, conservative, ondemand, powersave, and performance.

For example, my NSA325 box is set to ondemand. THe CUP is 1.6Ghz, but most of the time it is running at 533 MHz.

The u-boot settings are based on the latest version from LG. I did not make a backup out of ignorance, so I cannot say whether the settings were missing or whether I accidentally removed them.

# 4
The status today:
~USB only: runs
~HDD only: runs
~USB / HDD both with debian and labeled "rootfs": Boot from USB, then the system is seen on the HDD and continues to load from the HDD. Since I can drive with only HDD.
~USB / empty HDD: Boot from USB, then error due to empty HDD.

Lots of construction sites. Maybe there is a solution for # 1 first.

Thanks in advance.

This error was due to a bug in this stock u-boot. So try to set the envs inside Debian after you have booted, and at Linux shell. I recall somewhere in this thread I showed how to do that. Look for the /etc/fw_env.config setup info.

Not sure exactly what you are asking. But the envs listing can be copy/pasted to a notepad. u-boot image on flash can be dump to a file while you are inside Debian.

My idea for the setup:
Start and operation from USB, the HDD (with rootfs for operation without USB) then as personal data storage. Then "hdparm" should also work for the HDD.

The device starts well with two options:
1. Boot from HDD (without connected USB stick)
2. Boot from USB stick (without connected HDD)

If I operate the device with a USB stick and HDD at the same time, "Linux-5.2.9-kirkwood-tld-1" and "initramfs-5.2.9-kirkwood-tld-1" are loaded from the USB.
The operating system is then reloaded from the HDD and Debian works from the HDD. But I want to stay on the USB to put the HDD to sleep.


Can you help?


Thanks in advance.

This is why I have the bootargs with root device identifed by label rootfs

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

To make sure the HDD is not scanned by Debian when it tries to find the rootfs, check the HDD partitions label. If any of the partitions is labeled rootfs then change the partition label to something else such as Data, Music, Pictures... whatever is appropriate.

Hello Bodhi!

For this reason, I have already changed the entry "root =" to "rootfs_usb" in the past. The HDD has the label "data"
root=LABEL=rootfs_usb
My USB now has the label "rootfs" again, and it starts anyway!

1st part
Here a start with USB "rootfs" and an empty HDD "data". It is always started and loaded from USB, but /root is then expected on the HDD.

Can this be the reason?

This result when entered manually is good!

But what can you do for "1st part" so that /root is not searched for on sda?

Thanks in advance.

gf,

It should be always:
root=LABEL=rootfs

So in serial console, set it

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

The HDD is always initialized first in the kernel so it will take /dev/sda1. With the root label, you don't care how the kernel initialize the drives, it always look for a partition with label rootfs to mount as root.

Hello Bodhi!
Thank you for your help!

"saveenv" always worked. The change to "rootfs_usb" was my last entry.
Unfortunately "saveenv" can no longer be executed since then.

You gave me the hint for this:

This error was due to a bug in this stock u-boot. So try to set the envs inside Debian after you have booted, and at Linux shell. I recall somewhere in this thread I showed how to do that. Look for the /etc/fw_env.config setup info.

I am not sure what to do. Can you show me the place where you showed it?

Thanks in advance!

gf,

For now, use the new envs settings with the label, and make sure you can boot flawlessly.

Probably in this thread somewhere. Look for

/etc/fw_env.config
