Generic China "on-wall" router YTXC-958K 7628N

Hello,

I bought this "on wall" router from china.
It has Mediatek MT7628NN processor, 64MB RAM and 8MB flash
one USB port, 2x 100M LAN and 300Mbps wifi with 2 internals antennas
..same as many "cheap" routers...

But this device have OpenWrt inside "directly from manufacturer" ...

Is "any" kind of support from OpenWrt community ..??
cause USB port is unusable, no needed software inside.

I can build new firmware for this device, but I have no enough experiences with this (mean OpenWrt).
Backup of original firmware is not possible - from U-boot or web interface.
(it is needed for reverse engineering, dtb fetch

Is able build kernel and boot or mount rootfs from USB drive .?
(kernel from build directory "mt7628-kernel.bin" can boot from tftp with no problem)

Thanks.

There is no such thing as a generic router, embedded devices all come with their own peculiarities that need to be accounted for in device tree, network setup and image recipes. So your device will require its own, dedicated firmware image - for some devices this is easier than for others (ramips is generally towards the slightly easier side), but it will have to be done.

Hello, thanks for your post, but it is not answer for my question.

I know all of that things, as you talking about it.

.. and try to find any "homepage" for this router ..

That stock firmware looks like a manufacturer SDK build, the wifi drivers are not the open ones.

Are the SoC data lines connected to the USB port, or is it only for charging?

USB port is connected to SOC ...
kernel recognize any usb device

I have no shell via ttl line, ... (cause is missing in firmware)
Default username is root and password is admin ..
..but after successful login it do nothing ..

[ 2.352000] usb 1-1: new high-speed USB device number 2 using ehci-platform

Does the manufacturer provide any source for it?

I can't find any manufacter website..
I can't find real manufacter of this one..

Try to open aliexperess or alibaba and you can see many versions of one product.
it could be Outenga, Bcsongben, Wallpad or Waizmann

So .. U-boot command do something

now the question is, how to grab hex code from serial line to file ...

On a Linux PC, there should be xxd, with the -r option xxd can create a binary file out of hex text.

problem is single char value ..

hex 00 is "reported" as 0
hex 03 as 3 ..
etc.

it need to be reformated

(I must improve my skill)

EDITED: ...
..NO .. don't need

.. IT MUST BE REFORMATED ... !!

and grabbed as 64k blocks

..if anybody can play with this ..

Yes, I got it ..
and the real root for this router is "e-ruike"
just try any password, now...

(or try john)

Where is stored dts / dtb information in OpenWrt system..??
(..at the end of the kernel .. ?? )

..I can't find it ..
