if you computer has a real COM port (RS232), you need a null modem cable. if not (or you want to use usb), you need usb to com female cable (e.g. https://www.ozon.ru/product/kabel-usb-com-rs232-zhenskiy-807441393 )

Its true, but this cable layout will be "null-modem". You are have it?

And port speed will be 115200/

Hello everyone!!
I have several such hardware devices. I would like to reflash them in OpenWRT.
but here's the problem.....
I connect a USB serial port to the hardware, run the Putty program in Windows 7x64, supply power to the hardware, the download registration appears in the terminal, and when I am asked to press any button that would stop the download - I press the button (favorite) - the download continues.
how can I stop the download??

Hello!
I have a question about the DEPO thin client. I flashed it to openwrt. I bought a wi fi network card miniPCI QCA9880 https://aliexpress.ru/item/1005008370134260.html?sku_id=12000044750281965&spm=a2g2w.productlist.search_results.1.5e8f1ecdDZy1xk
I checked it on another computer, it works without problems. But DEPO does't see it. The lspci request outputs only the lan cards. That is, he does not see 9880 at all. Installing drivers doesn't help.
Maybe anyone had experience installing the same network card?

Jaskorro,

Welcome to club!:)

About you question, please, read first post in this topic, if you dont do it also.

Everything went well, configured as the main router, 1 port "WAN" 2 port LAN

Can you share the installation instructions?

installation instructions are in the text files at the links in the first post

Thanks for keeping going)

> dts with working pci-e in attach

Thanks!

+reset-gpios = <&gpio1 6 GPIO_ACTIVE_LOW>;

That was a good find! is it in the GPL source that we have overlooked before?

Unimportant suggestion: your version of the DTS does not have right spacing! could you use my file and retrofit the changes into it?

yes,

Thanks!

a good reason to dust off the thin client)

for now i still runing your build 23.05.5 on IP Plug (w/o USB & pci-e on the board) - it work fine

Is there a difference between stock u-boot, ubootzone-deb.bin and ubootzone-ow.bin
or only in envs preset?

stock u-boot = stock u-boot
ubootzone-deb.bin = stock u-boot + debian envs
ubootzone-ow.bin = stock u-boot + openwrt envs


made for simpler flashing (there are fewer steps in howto)

>>made for simpler flashing...


Thanks!

I'm dreaming of a NetConsole)))

now, leds and button also works

Thanks!

A good reason to update the IP Plug. Its LEDs are quite bright.

now, sound in debian also works
(in openwrt need custom kmods packages)

cmp 18

>sound...

Will there be graphics tomorrow?

Joke, of course)

now, video in debian also works (legacy drivers was ported)
(in openwrt need custom kmods packages and kernel patches)

buzzer also works

now, usb also works (need hw mod according pictures in openwrt folder) (+need kmod packet from version folder in openwrt)
NOT ACTUAL, SEE NEXT POST



Edited 3 time(s). Last edit at 10/07/2025 12:22PM by cmp18.

now, usb works without hw mods and dont need custom kmod packet installation

now, openwrt images = sysupgrade images.
so, now you can:
1) flash updates from web interface
2) make factory reset

cmp18,

Here is the DTS in pretty-print standard format for Linux. You could compile this and compare with your DTB to verify it's acurate.
