1.申请PSDK ID与KEY
申请链接：https://developer.dji.com/payload-sdk/apply/
2.申请通过后可以在用户中心中下载PSDK2.1.0的开发包
1.下载安装包，并解压
unzip Payload_SDK_V2.1.0.zip大家可以看下文件架构
doc/psdk_other_docs/psdk_code_style: Template files described code style of Payload SDK. doc/simple_model: Some structural models of Skyport 1/Skyport 2/X-Port and aircraft. The structure models provide convenience for users to design payload structure. psdk_lib/api_headers: Header files of Payload SDK, describing all API of Payload SDK. Users can understand features provided by Payload SDK and its usages relying on the header files. psdk_lib/lib: Library files of Payload SDK. Users select appropriate library file to use based on target platform. sample/api_sample: Sample code used to demonstrate usage of Payload SDK features. sample/platform: Sample code related to specific platform, including Linux and FreeRTOS platforms. sample/platform/linux/common/osal: OSAL layer implementation of Linux operation system. sample/platform/linux/manifold2: Sample project used on Manifold 2. sample/platform/rtos_freertos/common/osal: OSAL layer implementation of FreeRTOS operation system. sample/platform/rtos_freertos/psdk_development_board_1.0: Sample project used on Payload SDK development board 1.0. tools: Some tools used with Payload SDK.2.我们先修改Cmakelist.txt文件,位于Payload_SDK_V2.1.0-build.189/sample/platform/linux/manifold2/project
修改两个地方，第一处是编译链版本,将原来的gcc g++改为arm-linux-gnueabihf-gcc arm-linux-gnueabihf-g++
set(CMAKE_C_COMPILER "arm-linux-gnueabihf-gcc") set(CMAKE_CXX_COMPILER "arm-linux-gnueabihf-g++")
第二处修改PSDK链接库(如下直接注释原来的，添加以下两行)
link_directories(${CMAKE_CURRENT_LIST_DIR}/../../../../../psdk_lib/lib/arm-linux-gnueabihf-gcc) link_libraries(${CMAKE_CURRENT_LIST_DIR}/../../../../../psdk_lib/lib/arm-linux-gnueabihf-gcc/libpayloadsdk.a)
3.在app_info.h中填写申请的用户信息（文件路径/Payload_SDK_V2.1.0-build.189/sample/platform/linux/manifold2/application）
4.我们先注释掉一些不好适配的功能先让这个PSDK跑起来
注释psdk_config.h文件中的所有预定义：如图所示
注释main.c中的234-237行 289-297行 416-422行（可能随着版本变化 位置不一样请对照下面图片进行注释）
注释psdk_media_file_mp4.c文件中207-213行（可能随着版本变化 位置不一样请对照下面图片进行注释）
注释psdk_media_file_jpg.c文件170-176行（可能随着版本变化 位置不一样请对照下面图片进行注释）
注释osal.c文件63-68行（可能随着版本变化 位置不一样请对照下面图片进行注释）
到这里初步已经适配完成了，我们进行编译和试跑。
在project中新建文件夹build
mkdir build进行编译
cd build cmake .. make运行可执行文件
./psdk_demo
