点击左边菜单栏的Get BusyBix中的Download Source

跳转到busybox 的下载源码界面

有各个版本的busybox源码可以下载

BUSYBOX下载版本源码链接https://busybox.net/downloads/
点击链接后如图

也可以选择binaries 下载busybox去安装使用

android上安装busybox和使用示例

例如我下载的是1.31.0版本，用于安卓设备上，进行安装使用

一、下载

1.在Index of /downloads/binaries界面，点击1.31.0-defconfig-multiarch-musl版本

BUSYBOX版本下载链接https://busybox.net/downloads/binaries/1.31.0-defconfig-multiarch-musl/
点击链接后如图

2.查看android的构架

输入串口指令getprop |grep ro.product.cpu.abi

我的板子查看后是 armeabi-v7a

pxxx_xxx:/ # getprop |grep ro.product.cpu.abi
[ro.product.cpu.abi]: [armeabi-v7a]

3.在busybox-armv7l右击鼠标，选择将链接另存为

busybox-armv7l.txt

将busybox-armv7l.txt改成busybox

二、移动

可以用adb push 也可以用U盘cp

找到一个位置，将busybox放到位置。然后给777 的权限

C:\Users\Administrator>adb push C:\Users\Administrator\Downloads\busybox /data/busybox
C:\Users\Administrator\Downloads\busybox: 1 file pushed, 0 skipped. 110.3 MB/s (1152216 bytes in 0.010s)

C:\Users\Administrator>adb shell
pxxx_xxx:/ $ su
pxxx_xxx:/ # cd data/busybox/
pxxx_xxx:/data/busybox # ls -l
total 1132
-rw-rw-rw- 1 shell shell 1152216 2024-12-19 10:50 busybox
pxxx_xxx:/data/busybox # chmod 777 busybox

三、安装和设置环境变量

安装

./代表当前路径，安装在当前路径下，记住路径所在位置，用于设置环境变量

./busybox  --install ./

设置环境变量

/data/busybox是刚才的安装路径，如果安装在其它位置可以修改成安装的路径

export PATH=/data/busybox:$PATH

pxxx_xxx:/data/busybox # ./busybox  --install ./
pxxx_xxx:/data/busybox # export PATH=/data/busybox:$PATH
pxxx_xxx:/data/busybox # cd /
pxxx_xxx:/ # busybox
BusyBox v1.31.0 (2019-06-10 15:54:50 CEST) multi-call binary.
BusyBox is copyrighted by many authors between 1998-2015.
Licensed under GPLv2. See source distribution for detailed
copyright notices.

Usage: busybox [function [arguments]...]
   or: busybox --list[-full]
   or: busybox --show SCRIPT
   or: busybox --install [-s] [DIR]
   or: function [arguments]...

        BusyBox is a multi-call binary that combines many common Unix
        utilities into a single executable.  Most people will create a
        link to busybox for each function they wish to use and BusyBox
        will act like whatever it was invoked as.

四、使用

例如使用microcom 串口指令

microcom -t 5000 -s 115200 /dev/ttyS1

打开串口/dev/ttyS1，设置波特率115200，5s没操作退出

pxxx_xxx:/ # microcom -t 5000 -s 115200 /dev/ttyS1

# ls
[1;32mapp.elf[m                  [1;32mconfig.ini[m               [1;32mmnt.sh[m
[1;32marm-histbv320-linux-gdb[m  [1;32mfactory.elf[m              [1;32mreadme.txt[m
[1;32mautorun[m                  [1;32mfts_config.ini[m
# pxxx_xxx:/ #

busybox源码下载和查看

例如在Index of /downloads下载busybox-1.31.0.tar.bz2

解压后如图

Android源码上使用busybox

新建文件夹

新建一个busybox的文件夹
busybox文件夹里面放上arm和arm64的文件，arm和arm64文件夹里都是下载的busybox
busybox文件夹里面放上Android.mk

新建的busybox文件目录如图

arm的文件夹如图

Android.mk

在Android.mk里写上busybox模块的编译方式和路径等
例如我的写法1

LOCAL_PATH := $(call my-dir)
ifneq (,$(filter user userdebug eng,$(TARGET_BUILD_VARIANT)))
# busybox
include $(CLEAR_VARS)
LOCAL_MODULE := busybox
LOCAL_MODULE_TAGS := eng
LOCAL_MODULE_CLASS := EXECUTABLES
LOCAL_MODULE_STEM := $(LOCAL_MODULE)
LOCAL_SRC_FILES := $(TARGET_ARCH)/busybox
LOCAL_MODULE_TAGS := optional
LOCAL_PROPRIETARY_MODULE := true
LOCAL_MODULE_PATH := $(TARGET_OUT)/sbin
include $(BUILD_PREBUILT)
endif

例如我的写法2

LOCAL_PATH:= $(call my-dir)
include $(CLEAR_VARS)
LOCAL_SRC_FILES := $(TARGET_ARCH)/busybox
LOCAL_MODULE := busybox 
LOCAL_MODULE_TAGS := optional
LOCAL_MODULE_CLASS := EXECUTABLES
LOCAL_PROPRIETARY_MODULE := true
include $(BUILD_PREBUILT)

编译

mmm

mmm带路径编译
mmm external/busybox:busybox

mmm external/busybox:busybox

编译成功如图

mm

cd external/busybox
mm

android9$ cd external/busybox
android9/external/busybox$ mm

添加模块编译

找到会编译到的编译脚本里，如果是.mk文件里
添加
PRODUCT_PACKAGES +=
busybox2

PRODUCT_PACKAGES += \
    busybox2

会在编译时把busybox也编译上。
生成的路径是
out\target\product\xxxx\system\sbin\busybox
out\target\product\xxxx\vendor\bin\busybox
