Debian on AK Systems Thin client rev 1.3
September 12, 2024 02:51AM
Hello. I am writing for the first time on this forum, which I hardly found. I hope I can solve my question.
I apologize in advance if I am not correct in some way, because I am not well versed in firmware and have never assembled them.

There is a thin client "AK Systems Thin client rev 1.3" (referred to in Russia as "Depo Sky A60"), its characteristics:

Processor
Marvell Kirkwood 88F6282 (ARMv5TE) @ 1.6 GHz
Video
Marvell ARM integrated graphics
Flash
1 Gb
DRAM
1 Gb
Connectivity
10/100/1000 Ethernet (RJ-45) x2
Emulations
DVI-I digital video output (DVI to VGA adapter included)
I/O and peripheral support
6 USB 2.0; 2 RJ-45; 1 DVI-I; 1 headphone; 1 microphone in; DVI-I includes DVI-to-VGA adapter, COM port

Information: these devices were left forgotten, the company that dealt with them was closed. I want to put Debian (or another distribution) on it and have the opportunity to use it. The screen is not important to me, ssh, root, package installation and so on are important to me.
The presented Debian image from the company is a useless operating system. There is a terminal, but there is no data to it. In addition, the system was relevant for 2012.

The company left instructions and the source code of their operating system, which was called DEPO OS, sort of. I'm attaching the source code. (Description in Russian).

The main link to the firmware: https://vadimboev.ru/deposkya60/ak1100-recovery-full.zip
Source Linux and U-Boot: https://vadimboev.ru/deposkya60/build_mainline_u-boot_and_kernel_TC_v4.zip

https://vadimboev.ru/deposkya60/recoveryTC.zip
https://vadimboev.ru/deposkya60/tk_manual.pdf


I tried to update the u-boot and Debian firmware based on these instructions:
1. Linux Kernel 6.9.6 Kirkwood package and Debian rootfs (Updated 01 Nov 2023:)
2. Boot Kirkwood rootfs with stock u-boot

As a result, I got an eternal reboot and such an error:
Loading file "/boot/uImage" from usb device 0:1 (usbda1)
** File not found /boot/uImage
Loading file "/boot/uInitrd" from usb device 0:1 (usbda1)
** File not found /boot/uInitrd
Wrong Image Format for bootm command
ERROR: can't get kernel image!

At the moment, I have restored the firmware using "ak1100-recovery-full.zip"

I do not have a device on which Linux is installed, so to do all the manipulations for the USB-FLASH, I used an emulator via VirtualBox. However, it seems to me that this was a bad idea, and also the fact that I apparently do not understand at all how the firmware works, thereby I got an eternal reboot.
p.s. but if necessary, I can put Linux on the laptop in order to write the firmware to a USB FLASH drive or something.

If you need photos of the board, I can provide them.

Please help me install a more recent Debian (or something else) on this device. I hope for your help!

If you have kept the log of what you did in creating the rootfs (1), and also the u-boot booting (2), including all setenvs commands, please post them here.

Using VirtualBox is OK. But make sure you use command line to partition (fdisk) and format (mkfs.ext3) the USB drive. Don't use the GUI. And while you are creating the rootfs using tar command and so on, you must be root user.

Sorry, only a small piece was saved, which I have already attached to the post. Due to the fact that I am completely unsure of the actions that I did, I am ready to go all the way from the very beginning in order to try to install a firmware.

Yes, that's right, it was from root, I created an ext3 USB drive, I checked everything in this regard. And it was created from a terminal, not in a graphical shell

Vadim_Boev,

Loading file "/boot/uImage" from usb device 0:1 (usbda1)
** File not found /boot/uImage
Loading file "/boot/uInitrd" from usb device 0:1 (usbda1)
** File not found /boot/uInitrd

These errors mean u-boot could not find the kernel images. This usually happens if the USB partition was formatted as Ext4 and not "finalized". But you have verified that it is Ext3, so it's not that problem.

Power up with serial console connected, interrup u-boot at countdown, and

usb start

usb info
ext2ls usb 0:1 /boot

This is a common error with old stock u-boot. Try recreating the USB rootfs using a different USB thumb drive. Sandisk is among the best brand to use for rootfs.

Please keep the log of what you did, and also keep the entire serial boot log.

See https://promwad.com/case-studies/thin-client regarding development of this device. Perhaps reach out to PromWad to see if they are willing to provide the U-Boot source code for the device.

I provided all the source code with the first message that tech support gave. For example, the source code of U-Boot and Kernel is:

Okay, as soon as I find the SanDisk USB stick, I'll start. I would like to know what size a usb flash drive should be? 2 GB? 4 GB? 8 GB? 16 GB?
And also, since I'm not at all sure that I wrote the data to U-Boot correctly, could you write a sequence of commands for writing U-Boot via fdisk? I would be very glad

I would use 16GB, because Debian tends to growth. 16 GB will be good for a while before you need to migrate to larger disk.

No. u-boot is the boot loader. You are not writing the u-boot commands to the Debian rootfs. In the instruction

Boot Kirkwood rootfs with stock u-boot
https://forum.doozan.com/read.php?2,102054,105374#msg-105374

we set the envs at u-boot prompt in serial console.

See this post for a summary explanation about booting process.

I'm sorry, apparently I didn't express myself correctly. I mean, I need the right instructions for working with a USB flash drive, maybe I wrote something wrong on it. But I saw that it was in ext3 format and could only be read in a Linux environment. In Windows, after being created in ext3 format, it was naturally not detected.

U-Boot is fine with Ext2 and Ext3 partitions.

So post what you did and I'll correct it if I see something wrong.

Okay, I get you. In the next few days, I will look for a USB drive from SanDisk, and then I will try to install this whole thing again
