Build OpenWrt / LEDE from source

This topic should be placed under the image and logs spoiler

Description / What is discussed in the topic, and what is not

OpenWrt is an embedded Linux kernel-based operating system designed primarily for home routers. Core components include the Linux kernel, util-linux, uClibc or musl, and BusyBox. The source code is open. Distributed under licenseGNU GPL

The LEDE project is developed on the basis of Linux, an embedded meta-distribution based on OpenWRT, focused on a wide range of SOHO wireless routers and non-network devices. вЂњLinux Embedded Development EnvironmentвЂќ.
LEDE turned away from the parent project in May 2016, with the goal of continuing to develop better software in an open management model and encouraging new developers to contribute and development efforts.

This topic is intended to discuss the build process, discuss the components of the firmware for inclusion in the finished file for the firmware of your router and everything that is not related to the compilation of the firmware.
In this topicdon't discuss OpenWrt / LEDE settings, installation process of ready-made assemblies on your router. Questions like: "I installed OpenWrt and now I donвЂ™t know what to do, how to set up the Internet" is offtopic and will be deleted without any warnings. There is a general theme for such questions. OpenWrt / LEDE - alternative firmware

All manipulations are done on a computer with linux (in our example it will be for Debian / Ubuntu)
First, install everything you need.

Open the console and copy the commands there.

sudo apt-get install subversion git

Further

sudo apt-get install g ++ libncurses5-dev zlib1g-dev gawk libssl-dev unzip make

Is done.

Next you need to download the source of the firmware (see spoilerGit-repositories of OpenWrt and LEDE projects )

Download the branch we need (in this example, it is OpenWrt v17.01.4)

git clone git: //github.com/openwrt/openwrt.git -b v17.01.4

Next, go to the directory so that we download. ~ / (Ie home, he's home directory) we created openwrt directory, you need to go into it to continue

cd ~ / openwrt /

In Ubuntu, you can:

Now you need to run

./scripts/feeds update -a

After the update process is completed, we perform

./scripts/feeds install -a

Almost everything is ready, then we perform

make prereq

If everything is ok, then there will be this message: Collecting package info: done
Starting the interface for selecting the firmware components (in the latest versions it appears automatically after the previous step)

make menuconfig

Moving through the points is done with the keyboard keys: up-down, space and esc.
Target system

Target Profile can be selected for the desired model, if you leave the default profile then a lot of compiled firmware will be created for all devices at once from the Target System profile

Now a few simple explanations:
We put the web-interface

and Russian language to him

To support L2TP, you need to select the xl2tpd package.

Also the necessary protocols pptp and so on are selected here:
Network --->
<*>ppp
<*>ppp-mod-pppoe
<*>ppp-mod-pppol2tp
<*>ppp-mod-pptp

Add busybox components:

Well, then be guided by your needs, remember that the place in the router is not rubber and you often need to keep within 4 mb., So do not overdo it.
When everything is finished, save our configuration with the button<Save>
We proceed to the assembly:

make

And for 4-core processor, to enable all cores, the team will be: (number of cores 1, and here it turns out -j5)

make -j5 V = -1

Waiting over half an hour find its firmware in the directory ~ / openwrt /bin

If the correct target is selected before the build, but the firmware is obtained in a size larger than the size allowed for the flash of your router - the files * sysupgrade.bin and * factory.bin will not be created.

Cleaning

make clean

Removes the contents of the bin and build_dir directories.

make dirclean

Removes the contents of the / bin and / build_dir directories, as well as the addition of / staging_dir and / toolchain (cross-compilation tools). 'Dirclean' is the main command for a thorough cleanup.

make distclean

Removes everything that you have collected or configured, and also removes everything downloaded from the repository and the source codes of the packages.
ATTENTION: Among other things, your build configuration (.config), your toolchain, and all other source codes will be erased. Use with caution!

Addresses of the repositories used are in the file feeds.conf.default

WinSCPgraphical client SFTP and SCP

Settings for connecting to a router with LEDE (dropbear must be enabled)

Tftpd32

TFTP for Linux using Ubuntu as an example

Configure tftpd-hpa TFTP server

Install the tftpd-hpa package:

sudo apt-get install tftpd-hpa

After installation, edit the file

sudo nano / etc / default / tftpd-hpa

containing server settings. Let's bring it to the following form:

TFTP_USERNAME = "tftp"
TFTP_DIRECTORY = "/ var / tftp"
TFTP_ADDRESS = "0.0.0.0:69"
TFTP_OPTIONS = "- ipv4 --secure --create --umask 027 --permissive"

In the settings are additional options:
create allows the server to create new files,
ipv4 instructs it to wait for connections only on IPv4 addresses,
umask instructs to reset the write bit for the group and all access bits for other users,
permissive instructs not to carry out any file permissions checks in excess of the operating system.

Create a directory for the tftp server, give the server access to the directory:

sudo mkdir / var / tftp

sudo chown tftp: tftp / var / tftp

You can also change the home directory of the tftp user in the / etc / passwd file to / var / tftp.

Now we just write the ip addresses we need through the gnome network manager and that's it.

It remains to restart the daemon to start working with the new directory:

sudo /etc/init.d/tftpd-hpa restart

On the OpenWRT forum, I read about Zram-SWAP, allegedly for small devices helps to expand memory

Read in other places, and even in Russian. It is called Zram and Zswap, individual things. There is something in it, undoubtedly, but only if there are prerequisites for their use, in the sense if not enough memory. And you can do it, but do not notice the effect.

I did not find information in the header. Question on the assembly of firmware using Image Generator (Image Builder). To turn on the driven USB port on DIR 615 E4, you need to make changes to the AR71xx / Files / Arch / MIPS / AR71xx / Mach-DIR-600-A1.C file, namely add #include "dev-usb.h" after #include "dev-leds-gpio.h" and add ar71xx_add_device_usb (); After ar71xx_add_device_eth (1). I understand the * .c files is the code on C, and if you want to change something there, you will have to fully compile in Buildroot. Thus, image Builder is useless for me. Or, after all, you can take some correct file somewhere, and sign it in Image Builder?

The house lives: TV prefix, computer and four android. A multicast translation is always on the console, t.ch. Any peaks of the router processor are noticeable immediately. With the activated ZRAM system works noticeably faster and not overloaded.
Collected from the branch 18.0.6.1, added OpenVPN + Adblock. ZRAM himself can be seen on the status page, occupies<14MB.

Especially considering that on the compression of memory and \ or storage \ unpacking (with zswap) again, part of the projects leaves)))) zra with a lack of RAM use, and the ZSVOP with a shortage of memory for the swap

If in terms of costs to the upgrade do not need to spend more value of the device, then why not, I do not know how much it will cost if you give away somewhere.

Well, KABE on V9 is QCA9533-AL3A, which issues 366 bogomips, against V8 AR9341 on which is only 266. Therefore, it is not surprising. It just has experience on TL-WR741ND already CC started to slow down. But in general, we are wildly offtopim.

CrestFallen_Soul,
By default, the size of the SquashFS blocks is 256kib (Target for my router, for others I will not say) to shove as many packages as possible, the value is changed by 512 or 1024kib. The latter guarantees the maximum file system compression and almost megabytes of freedom, but the work with such blocks is much loading the processor. On third-party assemblies (SquashFS1024), which I experienced, the router often goes to the reboot, on our own "pancakes" - less often, but the Program is lit (IPTV is choking). Therefore, I collected without compression.

ATthe confirmationmy words

Increase Block Size from the Default 256 KB to Improve Compression. Warning: by Default 3 Blocks Will Be Cached So This Will Also Make The Router Use More Ram (IF 3 Blocks Are Cached, And A Block Size Of 1024 KB IS Used, This Will Use 2,304 KB More Ram (3 * 1024 KB - 3 * 256 Kb)). IT MAY ALSO Make The Router Use More CPU to Decompress The Larger Blocks.
