- 开发机需要使用linux环境，ubuntu16以上即可
- 下载我们提供的交叉编译器，就是很简单的交叉编译，具体使用可以百度或者问AI 点我下载编译器
- 解压到开发机工作目录， 比如
/home/test/gcc-linaro-5.3.1-2016.05-x86_64_arm-linux-gnueabihf
- 编写你的程序，比如我提供一个测试程序
#include <stdio.h>
#include <stdlib.h>
int main() {
printf("Hello World from ARM Linux!\n");
// 显示一些系统信息
printf("编译器: GCC\n");
printf("架构: ARM\n");
printf("操作系统: Linux\n");
return 0;
}
- 编译程序，非常需要注意
必须要使用静态链接参数-static ，否则程序最后无法再板子上运行。
- 比如编译上面的程序使用命令
/home/test/gcc-linaro-5.3.1-2016.05-x86_64_arm-linux-gnueabihf/bin/arm-linux-gnueabihf-gcc -static -o test test.c , 生成可执行程序test
- 为了方便直接给你个脚本
export PATH=$PATH:/home/test/gcc-linaro-5.3.1-2016.05-x86_64_arm-linux-gnueabihf/bin
export CC=arm-linux-gnueabihf-gcc
export CXX=arm-linux-gnueabihf-g++
$CC -static -o test test.c
- 使用ftp工具比如filezilla客户端，连接网关任意接口ip ，比如LAN口
192.168.10.1, 用户名zlftp,密码zlftp123
- 上传文件到upload目录
- 进入到nodered流程编辑页面，直接给你个测试流程，右上角导入。右边就是运行结果
