Thanks op, this would save me some time building one for myself.

Question: I vaguely remember the default kernel partition size is not enough for the latest 4.9.xxx kernel. Was it a problem, and if so how did you get around it?

AndyX · January 26, 2018, 2:16pm

Sorry my bad English.

This is not a problem, but suggested that you use the old version of the kernel.

The new version of the kernel will getting bigger, so I use the LEDE source code of 2017-12-28 version.

Making minimized firmware can properly enable/disable the following options(With BuildRoot):

1、Set Target Images Block size to 1024
Target Images - squashfs - Block size - 1024
Refer to https://www.gargoyle-router.com/phpbb/viewtopic.php?f=7&t=8614

2、Disable kernel debug and wireless debug
Global build settings - Kernel Build Options - everything
Kernel modules - Wireless Drivers - kmod-ath9k - Support for Ubiquiti Unify Outdoor+
Kernel modules - Wireless Drivers - kmod-mac80211 - Export mac80211 internals in DebugFS
Kernel modules - Wireless Drivers - kmod-ath - Force Atheros drivers to respect the user's regdomain settings, Enable DFS support
Refer to Build for TP-Link TL-WR841N(D) [all versions]

3、Remove OPKG & USB function

4、Enable Luci compress
LuCI - Modules - Minify Lua Sources

5、Enable data optimization
Remove ipkg/opkg status data files in final images
Strip unnecessary exports from the kernel image
Strip unnecessary functions from libraries
Refer to https://blog.yichyaqc.cn/openwrt-customize-2/

6、Find and remove other unrelated parts

tmomas · January 26, 2018, 2:49pm

I fail to understand the intention of your posting in the Developers category... Are you announcing your own build for devices with 4MB flash? If yes, then why should one choose your build over the tiny images added lately?

AndyX · January 26, 2018, 3:50pm

Yes. But those images did not include Luci, and my router just has only 4MB Flash, There is no space for installation.

I tried to seek help but no one helped me, so I was trying to build images by myself.

greyfreak19 · January 26, 2018, 5:37pm

This is quite an interesting build... Although why not put it in the Community Builds section? I do have a question though... How stable are these builds? In the other community build that I got for my 841n v9 the CPU spiked whenever I opened Luci after about ~24hours of uptime... it went down as soon as I closed the browser window though Or if I disable auto refresh that also stops the CPU from spiking. Seeing as how this build has a theme I'm curious if that changes anything or if it's still down to Luci.

Which router do you have this on btw? I might try this build and try to give any feedback I can if I get the time to get around to flashing and setting this up.

Lastly, Why not just go with the stable branch? or the 17.01.4 release? Wouldn't they be more stable?

AndyX · January 26, 2018, 7:51pm

1、Oops, my bad... now it's ok.
2、 Because I am working in the Iraq now, The generator switch once a week, so I can't do test for a long time.
I tested the longest for 7 days, P2P downloading, playing, and surfing on Internet. I believe the stability is absolutely no problem.
3、The theme source code copy from https://github.com/apollo-ng/luci-theme-darkmatter.git, very cool theme, and I like it very much.
4、The router model are TP-LINK TL-WR840N V2 (Eu) and TP-LINK TL-WR941ND V6

5、 Because the stable branch (17.01.4) does not include WR840N V2 model

stryker09 · January 27, 2018, 4:25pm

I understand you posted with support for the listed models, however I'd want to just be sure that WR841N(D) is supported as well?

Thanks for all your hard work, much appreciated as the other builds don't seem to be updated any more!

AndyX · February 1, 2018, 6:05am

Which Version of WR841N(D)？

I have tested WR840Nv2/WR841Nv9v10/WR941NDv6(CN)/WR1041Nv2, and working fine.

I believe there should be no problem because these models are generated from LEDE offical source code.

stryker09 · February 1, 2018, 11:29am

WR841NDV7 is the one

AndyX · February 5, 2018, 8:08am

It's been tested for 8 days.

greyfreak19 · February 5, 2018, 12:28pm

And it doesn't spike in CPU usage if you leave the status page open?

Also, I know you have to use the snapshot's to get one of your routers in there but... Snapshots are generally not for long-term use... I'd be more relaxed at night If I had a build from the stable branch.

Regardless, I think I might flash it this coming week to give some initial feedback on the build.

lucize · February 5, 2018, 8:05pm

define "not for long term use" ? and last time it was an programed update

(not exactly this image)

--> TP-LINK MR12u v2 is missing, your google drive has --> TP-LINK MR12u v1. Can you please upload V2

labrok · March 17, 2018, 4:47pm

A very important question to the developers!!! DOES TL-WA7210N V2 HAS SUPPORT FOR EXTERNAL ANTENNA? DEVICES LIKE THIS ONE ARE IN REMOTE PLACES AND ITS CRITICAL TO BE SURE BEFORE THEY BEING UPDATED, Official LEDE support for this router (TL-WA 7210N) is partial working, all antennas external or internal are not working with LEDE, does you have fixed it???? Thank you

lleachii · March 19, 2018, 5:33pm

How would the developers know?

So, it's not an external antenna problem, then?

You should probably make a new thread in "Hardware Questions and Recommendations."

labrok · March 21, 2018, 4:55pm

i am asking because this is special firmware maked by some people, if you mention a specific hardware as supported by what you have made then everybody may wonder if you have fixed some minor bugs, so the best you have to do is to listen to every question and answer with a yes or no, And YES i did wrote in hardware recommendtaion because nobody had ever mentioned that even internal antenna was not working and although in many forums people were asking about it, Nobody answered them,And many of them found out that their routers become broken after flashing, Only after i did wrote to the forum admins they have changed the router page with the no antenna is supported with this fw so dont try to flash it or you will get a broken box with terrible wifi signal. And because these boxes are in remote places with no easy access, every wrong flash means hard work to fix it.

AlvaroWalker · April 9, 2018, 12:08pm

any build to 840n v5?

acegabr1 · May 13, 2018, 2:51am

i got problem with my tp wr440 v2 eu i have connection lost for 10 sec and continue connection after 10sec how to fix this?
