static int cmd_hello(const struct shell *shell, size_t argc, char **argv)

    return 0;
}

    shell_print(shell, "Rebooting the system...");
    sys_reboot(SYS_REBOOT_COLD);
    return 0;
}

int main(void)

编译、烧录命令

在zephyr的目录中执行如何初始命令

cd D:/luglZephyrproject
export ZEPHYR_BASE=D:/luglZephyrproject/zephyr          # 正斜杠
export ZEPHYR_SDK_INSTALL_DIR=D:/luglZephyrproject/zephyr-sdk-1.0.1/zephyr-sdk-1.0.1
export ZEPHYR_TOOLCHAIN_VARIANT=zephyr
west build -b stm32wb5mm_dk -d build_stm32wb5mm_dk_shell app/stm32wb5mm_dk_shell

烧写：$ west flash -d build_stm32wb5mm_dk_shell

实现效果：
