..some update .. if any body read this ...

Power failure fixed by another new capacitor.

Now I have working buttons, and updated dts files for this board.
I'm found two versions of buttons order, one on PCB and other on COVER.
WiFi - RESET - WPS on pcb versus WPS - WiFi - RESET on front cover.

both dtb files are here:
http://195.28.90.62/dohc/ostatne/YTXC-985K/YTXC-958_MT7628NN-OnWall-Router_PCB.dtb
http://195.28.90.62/dohc/ostatne/YTXC-985K/YTXC-958_MT7628NN-OnWall-Router_COVER.dtb

and "my version" of OpenWrt firmware image for this router is here:
http://195.28.90.62/dohc/ostatne/YTXC-985K/openwrt-19.07.0-rc2-ramips-mt76x8-mt7628-squashfs-sysupgrade.bin

(this image has "COVER" buttons order)

"All stuff" about this is placed here: http://195.28.90.62/dohc/ostatne/YTXC-985K/
and is free for use ... for anybody ...

This router looks like a good cheap router... for common use ..

http://195.28.90.62/dohc/ostatne/YTXC-985K/owrt1907/wpa3/sha256sums

It is build with WPA3 support and image size is 6MB.

EDITED:
Links changed to actual image.
Device name changed from mt7628 to ytxc-958

Are you planning to add support to offical openwrt source repo?
Where are your source code? You have to share it if you have modified the GPLv2 code.

28

I will be happy, if it is in official source repository ...
but I don't know "how to add it" ...
(I'm newbee in this think)

All are there: http://195.28.90.62/dohc/ostatne/YTXC-985K/
actual work for 19.07 version is here: http://195.28.90.62/dohc/ostatne/YTXC-985K/owrt1907
and firmware image with changed name "ytxc-958" for this device is in http://195.28.90.62/dohc/ostatne/YTXC-985K/owrt1907/wpa3/ directory.

You aren't building from source with the build system?

32

I have downloaded imagebuilder https://downloads.openwrt.org/releases/19.07.0/targets/ramips/mt76x8/openwrt-imagebuilder-19.07.0-ramips-mt76x8.Linux-x86_64.tar.xz

use precompiled kernel, add my device tree file, compress kernel, add uimage header (mkimage command)...
modify some makefiles and any other files "in filesystem" ..
according this "how to" - https://openwrt.org/docs/guide-developer/adding_new_device

and then build image for "profile ytxc-958" ..
with make image PROFILE=ytxc-958 PACKAGES="luci luci-app-p910nd luci-app-ddns kmod-usb-printer kmod-usb-storage kmod-fs-vfat kmod-fs-exfat kmod-fs-ntfs kmod-fs-ext4 openssh-sftp-server block-mount hostapd-utils nfs-kernel-server wpad-openssl"

..thats all ...

It is "wrong" method .. ?? ..for this .. ??
...or ..??

I don't have any source code from vendor ..
It does not exist. ...

33

Hmm... I have never heard of anyone adding support for a new device based on Image Builder.
Indeed it will work, but think about if you have to patch some source code in the kernel or enable some config... This will never work with the image builder.

You should consider to use the "real" build system that builds everything from source:
https://openwrt.org/docs/guide-developer/build-system/start

If you have a device tree from the vendor image, you can decompile it with fdtdump (debian package: device-tree-compiler) and you have a lot of examples on the openwrt source directory.

If you integrate the needed changes into the build system you can create a pull request on github to add you support files to the official repo and you will get officially build images.

You can use trail and error like described in adding_new_device and the example dts files from the above linked github repo folder

34

So ..
I don't need compile anything from source, and modify some files in imagebuilder was easier way ..

Now I have not enough time to work with build system, and I haven't enough skill with openwrt builder.
Old kernel has no dtb, you can try to scan it .. http://195.28.90.62/dohc/ostatne/YTXC-985K/kernel.bin

New image for 19.07.01 ...

HI, DEAR

HOW ARE YOU

DEAR I HAVE AN OTHER ONE ROUTER SAME AS YOU HAVE BUT I HAVE AN PROBLEM DEAR MY ROUTER FIRMWARE HAS BEEN VANISHED/ REMOVED , AND MY ROUTER STOP WORKING , DEAR PLEASE HELP ME AND TELL ME THE COMPLETE METHOD HOW TO INSTALL THE FIRMWARE STEP BY STEP.
THANKS.[quote="JRD_McLAREN, post:1, topic:50111, full:true"]
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.

Vanished??
Richey Edwards from Manic Street Preachers vanished in 1995 ...

I'm not sure, if any "step-by-step" method exist....
(it is not washing machine)

Do you have .. ?

  • any serial cable (USB-TTL)
  • any terminal program
  • any knowledge with U-Boot
  • any knowledge with TFTP server
  • basic networking knowledge

(if the all answers are "YES", then put the image into tftpboot directory, configure static IP,connect TP cable, connect serial cable, run terminal program, power on the router and chose "1" )

38

Hello JRD_McLAREN,

I have the same device as yours.

It was rebooting randomly. I suppose it was related with power failure as you said before.

After I've tried to install the update(http://195.28.90.62/dohc/ostatne/YTXC-985K/owrt1907/wpa3/openwrt-19.07.0-ramips-mt76x8-ytxc-958-squashfs-sysupgrade.bin) from web interface it does not work in total.

It turns on but I can't connect to the router neither by wifi or ethernet cable.

How dou you think is it possible to solve the situation and fix the device?

Thank you in advance

39

you have any serial cable..???

40

Sorry, I don't know what it exactly is. Is cable USB type C to USB ok?

41

USB to TTL seral cable ..
or any bluetooth module HC-05 or HC-06

42

Unfortunately, I don't have any of it:(
