Configure the build Environment install virtual machine install Ubuntu 16.04LTS install git

1 2	sudo apt- sudo apt-get install git

Go to /optDirectories, and cloning Padavan warehouses with commands

Install the tools needed to compile the firmware

1	sudo apt-get install autoconf automake Bison build-essential Flex gawk gettext gperf libtool pkg-config zlib1g-D EV libgmp3-dev libmpc-dev libmpfr-Dev texinfo python-docutils MC

Compiling firmware for the 3.0 kernel

If you need to compile firmware for the 3.0 kernel, you need to perform the following steps, which support the 3.4 kernel by default

1 2 3

CD/Opt/rt-n56u/toolchain-mipsel sudo./clean_sources sudo./build_toolchain_3. 0.x

The compiled tool chain is placed in the/opt/rt-n56u/toolchain-mipsel/toolchain-3.0.x

You will need to perform the above steps later in the case of updating or upgrading the toolchain.

Model adaptation (Newifi mini) into the firmware source directory

Build configuration file

The. config file under Opt/rt-n56u/trunk, which is hidden by default, can be used to display and hide the configuration file using Ctrl+h (or delete it with the following command) Opt/rt-n56u/trunk and rename it to. config (or operate with the following command) Opt/rt-n56u/trunk/configs/templates/ac54_base.config/Opt/rt-n56u/trunk/.config

Modifying a configuration file

As a result of the changes in the default. config file in the document written in very detailed, not much explanation, according to their needs to open and close the need and unnecessary features, # the symbol is the default comment code, that is, to turn off a function, or vice versa is open (you can copy the contents of the document into the translation of the translation again, Can clearly see what each function is for.

Extended memory

To modify the /opt/rt-56u/trunk/configs/boards/RT-AC54U/kernel-3.4.x.config configuration file, take ac-54u as an example, the default is 64M, so you just need to change the following code as follows

Setting the time zone

Modify/opt/rt-56u/trunk/user/shared/defaults.h

1 2	#define Def_timezone"CST-8" #define DEF_NTP_SERVER0"ntp1.aliyun.com"

Generate firmware purge source tree

1	sudo./clear_tree

Start compiling the build firmware

1	sudo./build_firmware

Firmware generated after compilation is in the /opt/rt-56u/trunk/images inside

Update source

Go to /opt directory, clone the latest source

1 2	CD/opt sudo git pull

If you make changes to the local storage repository, you must run the following command when updating the source code

1 2	sudo git stash sudo git pull

If you change the toolchain, you must rebuild it

1 2 3 4

CD/Opt/rt-n56u/toolchain-mipsel sudo./clean_sources sudo./clean_toolchain sudo./build_toolchain

The above changes are recommended to use manual modification, if the direct use of files to overwrite, it is easy to error. and a compilation error, it takes a lot of time to adjust, so you can slowly change your own step by step.
