SUPPORT FOR TP-LINK TL-WR940N Ver 5.0

mportela · December 7, 2017, 1:06pm

Ok i Will use this method (sysupgrade) to test my custom firmware and my app.
But i Will need later to prepare this factory bin as you did to flash hundred devices.
And for this, i will try your method:

Use hex editor to change this value in factory-eu.bin form 4555 to 4252 and use mktplinkfw tool from firmware-utils to check MD5 sum and again correct MD5 in hex editor.

Do you have some tips to do this, or some other link forum ?

Thx

I prepare patch to make BR factory image:
Look here: https://github.com/heinzek/source/commit/4de3ccd42a31c02c9900fc97f40b89faaf34bda3
use command on your "source" directory:

wget https://github.com/heinzek/source/commit/4de3ccd42a31c02c9900fc97f40b89faaf34bda3.patch
patch -p1 < 4de3ccd42a31c02c9900fc97f40b89faaf34bda3.patch

i sent an email to the author: Matthias Schiffer asking for it and confirm this fix, just minutes before you send the patch, was the same thing!!!

Thank you

When i ask the author, he told me, to open a PR with the fix, do you will do that ?

I have a same problem when I try to flash to LEDE from stock, my device is TL-WR940N (VN). @Heinz could you help me build another version support VN region?
Thanks

hello @mportela. I have same router (TP LInk - WR 940N (BR) V5). In the box showed 256mb ram, but the tp-link support reply is have 32mb.

Pls, is possible confirm the detail. Is 32mb ram or 256mb ram?

Thanks

mportela · December 12, 2017, 5:36pm

@jucato, look for my commands from previous messages, "df -h" and "free -m", it looks 32 and not 256....

mportela · December 12, 2017, 6:31pm

HI @theday0314 i create a fix for implementing your REGION.

the fix is here for testing and waiting the previous PR to be merger by LEDE...

https://github.com/mportela/source/pull/3

I don't know how to send the image here in forum... but upload a VN version here for you if you can't compile it using my version:

mportela · December 12, 2017, 6:33pm

and @theday0314 if have some problem, try renaming the LEDE firmware file to a shorter name, such as factory.bin before...

theday0314 · December 12, 2017, 7:09pm

thanks so much, this works fine

theday0314 · December 13, 2017, 5:37am

I set my wireless channel: 11, width 40MHz, but receive only 20MHz, anyone get the bug like me? I try to change almost all channel, It has no effect

mportela · December 13, 2017, 11:55am

@theday0314 I'm a developer, not network expert, but i've tryed here the same config, and my clients are showing, in the status page that are conected in 20 MHz too.... but i can't say it's a bug or missconfig etc... maybe its better to add a new topic in the forum with this subject ?!

Heinz · December 13, 2017, 3:01pm

try add option noscan 1 to Your wireless config:

uci set wireless.radio0.noscan=1
uci commit wireless; wifi

Hey. I'm build an image for version 5. I choose only lucy and wpad. Build runs without errors, but files for the firmware does not appear. Advise what I'm doing wrong? Or, collect and give me sysupgrade.

tmomas · December 14, 2017, 4:35pm

TL-WR940N v5 has only 4MB flash, which makes it difficult to install additional packages.

Suggested reading (yes, you should read them all and thoroughly.):

https://lede-project.org/meta/infobox/432_warning - General advice regarding devices with low flash/RAM
https://lede-project.org/faq/after_installation#no_space_left_on_device - With only 250kB left for package installation, you will soon stumble over the error message No space left on device. The linked section shows some solutions.
https://lede-project.org/docs/user-guide/imagebuilder - You need to build your own space optimized image, with only the packages included that you really need. Imagebuilder is the easiest way to do so.
https://lede-project.org/faq/before_installation#which_packages_can_i_safely_remove_to_save_space - When you build your own image, you want to exclude unneeded packages to save space for needed packages.
https://lede-project.org/docs/user-guide/extroot_configuration - Another solution for the No space left on device problem (only for devices with USB port).

Hi, for me the firmware does not fit, constantly error 18005.
Make firmware for "RU" region.
A link to my original firmware. "https://static.tp-link.com/TL-WR940N(RU)_V5_170207.zip"
Thank you

mportela · February 21, 2018, 7:44pm

Hi strut06.

in my branch https://github.com/mportela/source/pull/3 i’ve done a version to BR and VN Regions.
You can follow this to make your firmware region, with some changes…

If you can’t do this by your own, reply here so i can try to compile one for your region and you can test it.
