Hi all,

Really need some help here!

Need to flash OpenWrt on this Chinese router  that already has some form of WRT.

It has a Realtek 3052F chip on board.

4 X Lan
1 X WAN
1 X Console
1 X USB
1 X 3g Module
1 X wifi Module

When I flash some of the variants of OpenWrt that matches my chip,  it stops at the following during boot and re-boots:

[    0.210000] jffs2: version 2.2 (NAND) (SUMMARY) (LZMA) (RTIME) (CMODE_PRIORITY) (c) 2001-2006 Red Hat, Inc.

[    0.230000] io scheduler noop registered
[    0.230000] io scheduler deadline registered (default)
[    0.240000] Serial: 8250/16550 driver, 16 ports, IRQ sharing enabled

I have extracted the original Chinese firmware and I have the following binwalk:

I have tried to build some kind of firmware with buildroot but it the boot process alwas stops as above.

They have provided me with the following "toolchains" (3.4.6-uclibc-0.9.28  4.1.0-uclibc-0.9.28) but I have no idea how to set up buildroot to use these toolchains.
Any attempt has failed with various errors.

can someone please tell me how to use the external toolchains and how to set it up?

meaning you have wrong serial speed (looks like your board use 115200 then typically ralink use 57600). Here is file where you can find all boards which use your speed. https://dev.openwrt.org/browser/branche … e/Makefile for example WR6202.

Tenda 3G300M -is wrong image, it have a little bit different arch, if I remember right.

It would be better if you print your original image bootlog.

Many thanks for reply neryba

tried flashing several images mentioned in the file but get the junk characters or just a reboot halfway through bootup:

Could it be that they modified the U-Boot so that this can happen? is there any pre-compiled U-boot I can flash?

Just in case it is of any use, here is the "printenv" of my u-boot:

I think you need to build own image, with correct partitions.

Great...

I'm not that good.

Any chance you (or someone) could look at it if I donate the board?

If it is a F3434 device you are talking about, then you have to unsolder R65 resistor from the back of the PCB to prevent the device from rebooting during the boot process. Don't ask how I know it
