Build the firmware from a source code
因为我使用的是 Ubuntu 18 编译。所以出现了不少需要打 patch 修复编译的问题。修复的方式都在后文给出。
Reference:
Build the firmware from a source code
This section describes how to build the firmware for LinkIt Smart 7688 and LinkIt Smart 7688 Duo development boards from a source code.
Environment
The following operations are performed under a Ubuntu LTS 14.04.3 environment. For a Windows or a Mac OS X host computer, you can install a virtual machine to have the same environment:
- Download Ubuntu 14.04.3 LTS image from http://www.ubuntu.com
- Install this image with VirtualBox (http://virtualbox.org) on the host machine. 50GB disk space reserved for the virtual machine is recommended.
Steps
In the Ubuntu system, open the Terminal application and enter the following commands:
-
Install prerequisite packages to build the firmware:
$ sudo apt-get install git g++ libncurses5-dev subversion libssl-dev gawk libxml-parser-perl unzip -
Download the OpenWrt CC source codes:
$ git clone git://git.openwrt.org/15.05/openwrt.git$ git clone https://github.com/openwrt/chaos_calmer.git linkit-7688 $ cd linkit-7688 linkit-7688$ git tag -l linkit-7688$ git checkout tags/v15.05.1 -b linkit7688 linkit-7688$Reference: Download a specific tag with Git
-
Prepare the default configuration file for feeds:
$ ##cd openwrt linkit-7688$ cp feeds.conf.default feeds.conf -
Add the LinkIt Smart 7688 development board’s feed:
linkit-7688$ echo src-git linkit https://github.com/MediaTek-Labs/linkit-smart-7688-feed.git >> feeds.conf -
Update the feed information for all available packages to build the firmware:
linkit-7688$ ./scripts/feeds updatecheck [./scripts/feeds update log](#./scripts/feeds update log) for more information.
-
Install all packages:

OpenWrt源码下载及固件编译
linkit-7688$ ./scripts/feeds install -acheck [./scripts/feeds install -a](#./scripts/feeds install -a) for more information.
-
Prepare the kernel configuration:
$ make menuconfig必须使用 v15.05.1 才有 MT7688（v15.05 没有 MT7688！）。
-
Select the following options:
- Target System: Ralink RT288x/RT3xxx
- Subtarget: MT7688 based boards
- Target Profile: LinkIt7688
-
Save and exit (use the default configuration file without any modification)
参见 [make menuconfig log](#make menuconfig log) for more detail.
-
-
Start the compilation process:
$ make V=99会下载 ***.tar.gz 到
/ /openwrt(or linkit7688)/dl/ -
After the build process is finished, the resulted firmware file will be under “bin/ramips/openwrt-ramips-mt7688-LinkIt7688-squashfs-sysupgrade.bin”. Depending on the hardware resources of the host environment, the build process may take more than 2 hours.
-
You can use this file to update the firmware through Web UI or rename it to lks7688.img to update through a USB drive.
Fix Compiler Fail
make V=99 issue, use patch to resolve:
