I found a post with instructions for N1T1 rebuild (very detailed). I have a N2B1 I would love to do this with but I can't seem to find any post specifically for this model. The two are very similar. Can someone point me in the right direction to where I may find more info or if N1T1 files are compatible or useful?

I had an N4B1 that I did a lot of work with ~ 2010 - 2014 and know quite a bit about that device, I suspect the N2B1 is basically the same. if that's the case it should have a pretty easily accessible serial header on the board.

I was able to boot the device using the device-tree for the "kurobox pro" which got network and some other things working. I believe if you enable pcie in the device tree it would also find the sata and you'd be off to a good start.

To test you could grab the debian installer images for this device and try booting them:
https://d-i.debian.org/daily-images/armel/daily/orion5x/network-console/buffalo/kuroboxpro/

all you have to do is rename uImage.buffalo and initrd.buffalo to match the filenames of the stock firmware, put them in place of those files and reboot. the device should come up into the debian installer. assuming that works you can grab the kuroboxpro dts file from the mainline kernel and start modifying it for the n2b1's hardware.

pjmaxx,

Yes. Do what 100.. said, to get it running using mainline kernel.

Additionally, instead of mainline kernel, if you want to use my released kernel and rootfs then what I would do is followed.

When you want to run a new box like this, list the specifications of both N1T1 and N2B1. And see what are the differences. And then take the N1T1 DTS file and modify it to eliminate those. You might or might not able to use the N1T1 DTS as a base to work from (if they use extactly the same SoC then it is likely that you can). Let me know if you need my help doing this.

Thank you both for the hints. I will start on this either later today or tomorrow afternoon. This unit has outlived its usefulness in its current state. It has served well in the past.

everything else seems the same at this point.

What software will I be needing?

Ok so reading through a few other post trying to get a good idea of what is or maybe needed. I am still a little confused about using uboot to navigate. I have successfully booted to uboot on the n2b1. I didn't have alot of time last night. I am assuming that LG replaced the uboot on their last system update back in 2011-12.
Is it necessary to replace uboot?
The ttl to usb adapter seemed laggy is that normal?
I am familiar with linux but no expert by any stretch of the imagination. I am learning. I look at winders all day. I have an extensive electronics, visual basic and .net background.

it's been a while since I worked on this one, sadly I didn't keep the greatest notes. You shouldn't have to replace uboot to get this working. as I recall the serial console feels pretty laggy which is fine.

I'd recommend starting by trying to boot into that debian installer I linked to earlier. The main advantage being that if sata doesn't work right away you'll still be able to work on getting that fixed from within the installers shell (it doesn't require a rootfs). Once you get your sata drives detected you can work on setting up a rootfs.

to start go back into uboot and run printenv. take a look at the bootcmd, it should load the kernel from /boot/uImage, I don't remember if it tries to load an initrd or not.

1. take blank drive, create a small (1gb) partition
2. format that partition as ext2, mount it
3. copy the uImage.buffalo (kernel) and initrd.buffalo (initrd) files to it
4. put that drive into the n2b1 and boot into uboot
5. manually enter a boot command similar to the one the device normally uses which loads those two files and then boots from them.

with any luck you should boot into the debian installer which will automatically launch and ssh server you can connect to and poke around.

once you're comfortable with that workflow we can set you up to start modifying the device tree and repacking the kernel to make it support more of the n2b1's hardware. once you get sata working you can move to a proper rootfs which will make testing the other hardware easier.

I have been trying different usb thumb drives with various formats ext2,ext3, ext4 etc...
I have even tried 2 usb hard drives.

but now matter what usb port (there are 3 on the unit) or drive.. I always get 0 storage devices found.
I am not sure where to go from here..

i'd recommend doing it from a hard drive to start, we know it will boot from that. @bohdi might have some advice for getting it to work if you want to pursue that route.

also it looks like this has a different SoC than the N4B1 did, rather than trying the kurobox image you'd want to try the ls-xl installer image instead to start.
Re: LG N2B1
February 23, 2019 12:57PM
pjmaxx,

This u-boot should have USB supports. But don't use USB hard disks. This u-boot is too old.

Which brand are these thumb drives? have you tried a Sandisk brand?

Yes Sandisk, Kingston and samsung.
Booting from hard drive would be just fine.
Like I said before learning curve..

Sorry for being such a noob but I can't seen to locate ls-xl image. probably over looking it
is this the correct location?

Re: LG N2B1
February 24, 2019 08:37AM
My bad, I think I directed you at something that doesn't exist for that one.

looking at the dts files in the mainline kernel I see the following options:

kirkwood-blackarmor-nas220.dts
kirkwood-laplug.dts
kirkwood-ns2lite.dts
kirkwood-ns2mini.dts
kirkwood-pogoplug-series-4.dts
kirkwood-rd88f6192.dts

you could try the lacie ns2 files as a start:

Re: LG N2B1
February 24, 2019 02:31PM
This box is close cousin of Pogoplug V4 and NS2 Lite.

Quote

N2B1
88F6192
800Mhz ram

Lacie NS2 is not. NS2 is 88F6281, just like the LG N1T1.

So if pjmaxx wants to use mainline DTS, look to use one of these:

kirkwood-blackarmor-nas220
kirkwood-laplug
kirkwood-ns2lite
kirkwood-ns2mini
kirkwood-pogoplug-series-4 
(this kirkwood-pogoplug-series-4 is the mainline version, my version in kernel linux-4.20.6-kirkwood-tld-1 is different).

Sorry to repeat, I did not see 100... post above :)

nice, that's a good starting point. getting it to boot is half the battle and you've already managed that.

it looks like it didn't find your hard drive(s) but we were expecting that. you can confirm this by trying to run through the installer, i'm guessing it will say it can't find any disks.

hopefully you can find it on the network, you should be able to connect over ssh:
username=installer
password=install

next we need to get you set up to modify the device-tree so you can start customizing the device tree for this device.

do you have (or can you get) the dmesg output of the stock kernel? that will be really helpful for determining some info about the hardware you'll want to add to the device tree

It found the network.
I did run it through the installer.. It did not find hard drive.
SSH seems to work as expected.

I will continue tomorrow afternoon and get the dmesg.

Thanks for the help.
Re: LG N2B1

typically when I start modifying/testing a device tree I setup a full kernel crosscompile environment with some scripts to make executing the build and packaging the resulting dtb file with the kernel easier.

I can help you set something like that up for your testing but I suspect there is an easier way. I'm curious to compare notes with @bohdi who seems to do this more than I do.

Re: LG N2B1

Here is the basic process for getting started modifying the device tree (example shows just building the one you've already tested).

#install the needed tools and source (for the dts file)
apt-get install device-tree-compiler linux-source-4.9 u-boot-tools

#grab the installer initrd (it's already packaged and ready for use)
wget "http://ftp.nl.debian.org/debian/dists/stretch/main/installer-armel/current/images/kirkwood/network-console/lacie/uInitrd";

#grab the plain kernel (we need to package our own since we're using a custom dtb)
wget "http://ftp.nl.debian.org/debian/dists/stretch/main/installer-armel/current/images/kirkwood/netboot/vmlinuz-4.9.0-8-marvell";

#pull out the NS2 dts file from the kernel source
tar xvf /usr/src/linux-source-4.9 --wildcards --strip-components=4 arch/arm/boot/dts/kirkwood-ns2.dts

#build a DTB out of it
dtc -I dts -O dtb -f kirkwood-ns2.dts -o kirkwood-ns2.db

#append the dtb to the kernel
cat vmlinuz-4.9.0-8-marvell kirkwood-ns2.db > kernelDTB

#package the kernel for uboot
mkimage -A arm -O linux -T Kernel -C none -a 0x00008000 -e 0x00008000 -n debian_installer -d kernelDTB uImage

Now you should be able to boot uImage and uInitrd. you can then make changes to the dts as desired and generate a new uImage by re-running the last 3 steps as needed.

actually I think you'll need to grab the needed include files out of the kernel source too:
kirkwood-6281.dtsi
kirkwood-ns2-common.dtsi
kirkwood.dtsi

I think moving forward you'll want to try to eliminate kirkwood-ns2-common.dtsi as a dependency but I'd suggest verifying you can successfully build a DTB before moving forward with actually editing one.

I took a stab at a first dts specific to this device, it's based on the NS2 dts but with some changes:
removed anything that showed as failing in your initial boot
removed anything specific to lacie or the NS2
removed the dependency on kirkwood-ns2-common.dtsi
adjusted the ram to the correct size
enabled pcie which will hopefully allow sata to be detected

I confirmed it will build without an error but I don't know if it will work or not.

excellent.

Looks like I was wrong about sata being pcie, that’s good to know. Also good info about the rtc/nand/etc all of which will help when we get that far.

I took another stab at the dts based on what we can see from that console output.

I made sure it compiles but am not sure whether it would actually work. I'd recommend building the same dtb you've been using first to verify your able to successfully build/package them before trying mine.
