Zephyr_01, environment

前言

使用qemu_cortex_m3模拟的板子

目录结构

SDK和测试工程路径如下

测试工程目录结构如下

复制代码

wwl@wwl-pc:~/testprj/0_mode$ tree .
.
├── CMakeLists.txt
├── hp.sh
├── prj.conf
└── src
    ├── app.c
    └── main.c

main.c内容如下

c 复制代码

#include <zephyr/kernel.h>

int main(void)
{
   return 0;
}

app.c是测试工程，我会在这里做一些测试任务

CMakeLists.txt

复制代码

cmake_minimum_required(VERSION 3.20.0)

set(BOARD qemu_cortex_m3)
set(ENV{ZEPHYR_BASE} "/home/wwl/zephyrproject/zephyr")

find_package(Zephyr REQUIRED HINTS ${ZEPHYR_BASE})

project(hello)

target_sources(app PRIVATE src/main.c)
target_sources(app PRIVATE src/app.c)

prj.conf工程配置文件

复制代码

CONFIG_QEMU_ICOUNT=y
CONFIG_QEMU_ICOUNT_SHIFT=5
CONFIG_QEMU_ICOUNT_SLEEP=y

hp.sh我打包了一些编译相关指令，不爱用west

sh 复制代码

Vscode配置

.vscode/launch.json 这个文件让我可以使用GDB调试

复制代码

    "version": "0.2.0",
    "configurations": [
        {
            "name": "Attach GDB to QEMU",

                }
            ]
        }
    ]
}

.vscode/settings.json VScode 配置文件，主要是排除SDK中的venv和west文件

复制代码
