sdk镜像的使用
sdk文件由：sdk-tools、sdk、build-tools、platform-tools、其他文件其中：1.sdk-tools文件是基础框架，相当于容器，存放sdk,build-tools,platforms,platforms，system-images这几个关键文件2. SDK文件是版本文件，如android4.0，android5.0,一个sdk-tools里可以有多个sdk文件，这样就可以支持多版本3. system-image文件是sdk版本支持文件，和sdk要一一对应4.build-tools文件是开发文件，没有的话，会导致R cannot be resol ved as a ...错误5. platform-tools文件，还不知道现在，嘻嘻所以步骤是：1.解压sdk-tools文件，就在里面创建build-tools文件夹，platforms文件夹，platform-tools文件夹（如果有就不用手动创建）2.把sdk文件解压，把整个文件夹放到platforms文件夹里（记住是整个文件夹）3.把build-tools文件解压，把整个文件夹放到build-tools文件夹里（记住是整个文件夹）4.把platform-tools文件解压，把所有文件放到platform-tools文件夹里(不是文件夹，是所有文件)5.把system-images文件解压，把整个文件夹放到system-images文件夹里，如果没有这个文件，虚拟机就无法创建（记住是整个文件夹）说明：platforms文件夹里可以放置多个sdk文件夹，这样就可以进行多android版本开发因此，为了对应支持sdk版本，system-images文件夹里也要存放对应sdk的system-images 文件然后就大功告成。

NXP SCM-i.MX 6 Series Yocto Linux 用户指南说明书
© 2017 NXP B.V.SCM-i.MX 6 Series Yocto Linux User'sGuide1. IntroductionThe NXP SCM Linux BSP (Board Support Package) leverages the existing i.MX 6 Linux BSP release L4.1.15-2.0.0. The i.MX Linux BSP is a collection of binary files, source code, and support files that can be used to create a U-Boot bootloader, a Linux kernel image, and a root file system. The Yocto Project is the framework of choice to build the images described in this document, although other methods can be also used.The purpose of this document is to explain how to build an image and install the Linux BSP using the Yocto Project build environment on the SCM-i.MX 6Dual/Quad Quick Start (QWKS) board and the SCM-i.MX 6SoloX Evaluation Board (EVB). This release supports these SCM-i.MX 6 Series boards:• Quick Start Board for SCM-i.MX 6Dual/6Quad (QWKS-SCMIMX6DQ)• Evaluation Board for SCM-i.MX 6SoloX (EVB-SCMIMX6SX)NXP Semiconductors Document Number: SCMIMX6LRNUGUser's GuideRev.

Enabling Linux OS for SCM-i.MX 6Dual/6Quad/SoloXThis section describes how to obtain the SCM-related build environment for Yocto. This assumes that you are familiar with the standard i.MX Yocto Linux OS BSP environment and build process. If you are not familiar with this process, see the NXP Yocto Project User’s Guide (available at L4.1.15-2.0.0_LINUX_DOCS).2.1. Host setupTo get the Yocto Project expected behavior on a Linux OS host machine, install the packages and utilities described below. The hard disk space required on the host machine is an important consideration. For example, when building on a machine running Ubuntu, the minimum hard disk space required is about 50 GB for the X11 backend. It is recommended that at least 120 GB is provided, which is enough to compile any backend.The minimum recommended Ubuntu version is 14.04, but the builds for dizzy work on 12.04 (or later). Earlier versions may cause the Yocto Project build setup to fail, because it requires python versions only available on Ubuntu 12.04 (or later). See the Yocto Project reference manual for more information.2.2. Host packagesThe Yocto Project build requires that the packages documented under the Yocto Project are installed for the build. Visit the Yocto Project Quick Start at /docs/current/yocto-project-qs/yocto-project-qs.html and check for the packages that must be installed on your build machine.The essential Yocto Project host packages are:$ sudo apt-get install gawk wget git-core diffstat unzip texinfo gcc-multilib build-essential chrpath socat libsdl1.2-devThe i.MX layers’ host packages for the Ubuntu 12.04 (or 14.04) host setup are:$ sudo apt-get install libsdl1.2-dev xterm sed cvs subversion coreutils texi2html docbook-utils python-pysqlite2 help2man make gcc g++ desktop-file-utils libgl1-mesa-dev libglu1-mesa-dev mercurial autoconf automake groff curl lzop asciidocThe i.MX layers’ host packages for the Ubuntu 12.04 host setup are:$ sudo apt-get install uboot-mkimageThe i.MX layers’ host packages for the Ubuntu 14.04 host s etup are:$ sudo apt-get install u-boot-toolsThe configuration tool uses the default version of grep that is on your build machine. If there is a different version of grep in your path, it may cause the builds to fail. One workaround is to rename the special versi on to something not containing “grep”.3. Building Linux OS for SCM i.MX platforms3.1. Setting up the Repo utilityRepo is a tool built on top of GIT, which makes it easier to manage projects that contain multiple repositories that do not have to be on the same server. Repo complements the layered nature of the Yocto Project very well, making it easier for customers to add their own layers to the BSP.To install the Repo utility, perform these steps:1.Create a bin folder in the home directory.$ mkdir ~/bin (this step may not be needed if the bin folder already exists)$ curl /git-repo-downloads/repo > ~/bin/repo$ chmod a+x ~/bin/repo2.Add this line to the .bashrc file to ensure that the ~/bin folder is in your PATH variable:$ export PATH=~/bin:$PATH3.2. Installing Yocto Project layersAll the SCM-related changes are collected in the new meta-nxp-imx-scm layer, which is obtained through the Repo sync pointing to the corresponding scm-imx branch.Make sure that GIT is set up properly with these commands:$ git config --global "Your Name"$ git config --global user.email "Your Email"$ git config --listThe NXP Yocto Project BSP Release directory contains the sources directory, which contains the recipes used to build, one (or more) build directories, and a set of scripts used to set up the environment. The recipes used to build the project come from both the community and NXP. The Yocto Project layers are downloaded to the sources directory. This sets up the recipes that are used to build the project. The following code snippets show how to set up the SCM L4.1.15-2.0.0_ga Yocto environment for the SCM-i.MX 6 QWKS board and the evaluation board. In this example, a directory called fsl-arm-yocto-bsp is created for the project. Any name can be used instead of this.Building Linux OS for SCM i.MX platforms3.2.1. SCM-i.MX 6D/Q quick start board$ mkdir fsl-arm-yocto-bsp$ cd fsl-arm-yocto-bsp$ repo init -u git:///imx/fsl-arm-yocto-bsp.git -b imx-4.1-krogoth -m scm-imx-4.1.15-2.0.0.xml$ repo sync3.2.2. SCM-i.MX 6SoloX evaluation board$ mkdir my-evb_6sxscm-yocto-bsp$ cd my-evb_6sxscm-yocto-bsp$ repo init -u git:///imx/fsl-arm-yocto-bsp.git -b imx-4.1-krogoth -m scm-imx-4.1.15-2.0.0.xml$ repo sync3.3. Building the Yocto imageNote that the quick start board for SCM-i.MX 6D/Q and the evaluation board for SCM-i.MX 6SoloX are commercially available with a 1 GB LPDDR2 PoP memory configuration.This release supports the imx6dqscm-1gb-qwks, imx6dqscm-1gb-qwks-rev3, and imx6sxscm-1gb-evb. Set the machine configuration in MACHINE= in the following section.3.3.1. Choosing a machineChoose the machine configuration that matches your reference board.•imx6dqscm-1gb-qwks (QWKS board for SCM-i.MX 6DQ with 1 GB LPDDR2 PoP)•imx6dqscm-1gb-qwks-rev3 (QWKS board Rev C for SCM-i.MX 6DQ with 1GB LPDDR2 PoP) •imx6sxscm-1gb-evb (EVB for SCM-i.MX 6SX with 1 GB LPDDR2 PoP)3.4. Choosing a graphical back endBefore the setup, choose a graphical back end. The default is X11.Choose one of these graphical back ends:•X11•Wayland: using the Weston compositor•XWayland•FrameBufferSpecify the machine configuration for each graphical back end.The following are examples of building the Yocto image for each back end using the QWKS board for SCM-i.MX 6D/Q and the evaluation board for SCM-i.MX 6SoloX. Do not forget to replace the machine configuration with what matches your reference board.3.4.1. X11 image on QWKS board Rev C for SCM-i.MX 6D/Q$ DISTRO=fsl-imx-x11 imx6dqscm-1gb-qwks-rev3 source fsl-setup-release.sh -b build-x11$ bitbake fsl-image-gui3.4.2. FrameBuffer image on evaluation board for SCM-i.MX 6SX$ DISTRO=fsl-imx-fb MACHINE=imx6sxscm-1gb-evb source fsl-setup-release.sh –b build-fb-evb_6sxscm$ bitbake fsl-image-qt53.4.3. XWayland image on QWKS board for SCM-i.MX 6D/Q$ DISTRO=fsl-imx-xwayland MACHINE=imx6dqscm-1gb-qwks source fsl-setup-release.sh –b build-xwayland$ bitbake fsl-image-gui3.4.4. Wayland image on QWKS board for SCM-i.MX 6D/Q$ DISTRO=fsl-imx-wayland MACHINE=imx6dqscm-1gb-qwks source fsl-setup-release.sh -b build-wayland$ bitbake fsl-image-qt5The fsl-setup-release script installs the meta-fsl-bsp-release layer and configures theDISTRO_FEATURES required to choose the graphical back end. The –b parameter specifies the build directory target. In this build directory, the conf directory that contains the local.conf file is created from the setup where the MACHINE and DISTRO_FEATURES are set. The meta-fslbsp-release layer is added into the bblayer.conf file in the conf directory under the build directory specified by the –e parameter.4. Deploying the imageAfter the build is complete, the created image resides in the <build directory>/tmp/deploy/images directory. The image is (for the most part) specific to the machine set in the environment setup. Each image build creates the U-Boot, kernel, and image type based on the IMAGE_FSTYPES defined in the machine configuration file. Most machine configurations provide the SD card image (.sdcard), ext4, and tar.bz2. The ext4 is the root file system only. The .sdcard image contains the U-Boot, kernel, and rootfs, completely set up for use on an SD card.4.1. Flashing the SD card imageThe SD card image provides the full system to boot with the U-Boot and kernel. To flash the SD card image, run this command:$ sudo dd if=<image name>.sdcard of=/dev/sd<partition> bs=1M && syncFor more information about flashing, see “P reparing an SD/MMC Card to Boot” in the i.MX Linux User's Guide (document IMXLUG).Specifying displays4.2. MFGTool (Manufacturing Tool)MFGTool is one of the ways to place the image on a device. To download the manufacturing tool for the SCM-i.MX 6D/Q and for details on how to use it, download the SCM-i.MX 6 Manufacturing Toolkit for Linux 4.1.15-2.0.0 under the "Downloads" tab from /qwks-scm-imx6dq. Similarly, download the manufacturing tool for the SCM-i.MX 6SoloX evaluation board under the "Downloads" tab from /evb-scm-imx6sx.5. Specifying displaysSpecify the display information on the Linux OS boot command line. It is not dependent on the source of the Linux OS image. If nothing is specified for the display, the settings in the device tree are used. Find the specific parameters in the i.MX 6 Release Notes L4.1.15-2.0.0 (available at L4.1.15-2.0.0_LINUX_DOCS). The examples are shown in the following subsections. Interrupt the auto-boot and enter the following commands.5.1.1. Display options for QWKS board for SCM-i.MX 6D/QHDMI displayU-Boot > setenv mmcargs 'setenv bootargs console=${console},${baudrate} ${smp}root=${mmcroot} video=mxcfb0:dev=hdmi,1920x1080M@60,if=RGB24'U-Boot > run bootcmd5.1.2. Display options for EVB for SCM-i.MX 6SXNote that the SCM-i.MX 6SX EVB supports HDMI with a HDMI accessory card (MCIMXHDMICARD) that plugs into the LCD connector on the EVB.Accessory boards:•The LVDS connector pairs with the NXP MCIMX-LVDS1 LCD display board.•The LCD expansion connector (parallel, 24-bit) pairs with the NXP MCIMXHDMICARD adapter board.LVDS displayU-Boot > setenv mmcargs 'setenv bootargs console=${console},${baudrate} ${smp}root=${mmcroot} ${dmfc} video=mxcfb0:dev=ldb,1024x768M@60,if=RGB666 ldb=sep0'U-Boot > run bootcmdHDMI display (dual display for the HDMI as primary and the LVDS as secondary)U-Boot > setenv mmcargs 'setenv bootargs console=${console},${baudrate} ${smp}root=${mmcroot} video=mxcfb0:dev=hdmi,1920x1080M@60,if=RGB24video=mxcfb1:dev=ldb,LDBXGA,if=RGB666'U-Boot > run bootcmdLCD displayu-boot > setenv mmcargs 'setenv bootargs ${bootargs}root=${mmcroot} rootwait rw video=mxcfb0:dev=lcd,if=RGB565'u-boot> run bootcmd6. Reset and boot switch configuration6.1. Boot switch settings for QWKS SCM-i.MX 6D/QThere are two push-button switches on the QWKS-SCMIMX6DQ board. SW1 (SW3 for QWKS board Rev B) is the system reset that resets the PMIC. SW2 is the i.MX 6Dual/6Quad on/off button that is needed for Android.There are three boot options. The board can boot either from the internal SPI-NOR flash inside the SCM-i.MX6Dual/6Quad or from either of the two SD card slots. The following table shows the switch settings for the boot options.Table 1.Boot configuration switch settingsBoot from top SD slot (SD3)Boot from bottom SD slot (SD2)Boot from internal SPI NORDefault1.References6.2.

二、常见的Linux下的SDK案例1. GNU C Library (glibc) SDKGNU C Library是Linux系统中最基本的库之一，提供了许多与C 语言程序设计相关的函数和接口。
glibc SDK可以帮助开发者进行系统编程，包括文件操作、进程管理、网络通信等。
2. GTK SDKGTK是一套用于创建图形用户界面的工具包，被广泛应用于Linux 下的应用程序开发中。
GTK SDK提供了一系列的库和工具，使得开发者可以轻松创建漂亮、功能丰富的图形界面应用程序。
3. Qt SDKQt是一个跨平台的应用程序开发框架，支持多种操作系统，包括Linux。
Qt SDK提供了一套完整的开发工具和库，使得开发者可以使用C++语言进行图形界面应用程序的开发。
4. ALSA SDKALSA（Advanced Linux Sound Architecture）是Linux下的音频驱动架构，提供了一套完整的音频处理和控制的接口。
ALSA SDK 提供了用于音频应用程序开发的库和工具，开发者可以使用它来实现音频播放、录制、混音等功能。
5. OpenSSL SDKOpenSSL是一个开源的加密库，提供了各种密码学算法和安全协议的实现。
OpenSSL SDK为开发者提供了一系列的函数和接口，使得开发者可以在Linux下进行网络通信的加密和解密操作。
6. OpenCV SDKOpenCV是一个开源的计算机视觉库，提供了一系列的图像处理和计算机视觉算法的实现。

linux sdk命令的用法 -回复
linux sdk命令的用法-回复Linux SDK命令的用法Linux是一种开源操作系统，为开发者提供了丰富的软件开发工具和应用程序接口，以构建各种类型的应用程序。
Linux SDK（Software Development Kit）是一组用于开发Linux应用程序的工具、库和文档。
它包括编译器、调试器、开发库和示例代码等，为开发者提供了一站式的开发环境。
本文将逐步介绍Linux SDK命令的用法。
第一步：安装Linux SDK首先，我们需要在Linux系统上安装Linux SDK。
这通常可以通过包管理器或从官方网站下载SDK。
一旦安装完成，我们可以开始使用其中的命令和工具。
第二步：使用编译器Linux SDK包含了一个强大的编译器集合，用于将源代码编译成可执行文件。
最常用的是GNU编译器套件（GCC），它支持多种编程语言，如C、C++、Objective-C等。
下面是GCC的一些常用命令：1. gcc：编译C源代码文件。
例如，gcc -o hello hello.c将hello.c文件编译为名为hello的可执行文件。
2. g++：编译C++源代码文件。
类似于gcc命令，可以使用g++命令来编译C++程序。
3. gcc -c：只进行编译而不链接。
这个命令生成目标文件（.o文件），可以在后续的步骤中使用。
4. gcc -E：预处理源代码文件。
这个命令将宏展开、头文件包含等预处理指令应用到源代码文件中。
5. gcc -g：生成带有调试信息的可执行文件。
使用这个选项可以在调试程序时获得更多的信息。
除了GCC，Linux SDK还提供了其他编译器，如LLVM（低级虚拟机），它支持更多的编程语言和编译优化。
第三步：使用调试器在开发过程中，调试器是一个非常重要的工具，用于定位和修复代码中的错误。
Linux SDK提供了多个调试器，如GDB（GNU调试器）和LLDB（LLVM调试器）。
下面是一些调试器的使用命令：1. gdb：启动GDB调试器。
