RT-Thread for x86
这是一份基础的RT-Thread针对x86的版本、移植,主要是能够在qemu中执行。以下说明主要针对Linux的环境,如果是Windows环境,请使用Env工具,同时请自行处理生成iso的方法。
编译
编译RT-Thread for x86版本,还需要一份支持newlib的工具链,可以通过以下地址获得:
*i386-unknown-elf_for_x86_64-pc-linux-gnu_latest.tar.bz2
下载后解压,然后在rtconfig.py中配置其中的EXEC_PATH变量
if CROSS_TOOL == 'gcc':
PLATFORM = 'gcc'
EXEC_PATH = os.getenv('RTT_EXEC_PATH') or 'E:/Program Files/CodeSourcery/Sourcery_CodeBench_Lite_for_IA32_ELF/bin'
然后在x86 bsp目录下执行scons命令来编译:
scons
配置
RT-Thread for x86的版本也支持menuconfig的配置方式,在Linux下可以使用scons --menuconfig
的方式进行配置。
因为menuconfig是一份字符界面的配置(Kconfig),在ubuntu下需要安装ncurses5的库
sudo apt install libncurses5-dev
运行
在ubuntu下运行,请确保你安装了qemu-system-i386
,grub
以及 xorriso
软件包:
sudo apt install qemu-system-x86 grub-common xorriso
然后执行./run.sh
命令可以使用qemu来模拟执行(它也会生成可启动的iso文件)
~/workspace/rt-thread/bsp/x86$ ./run.sh

在qemu下可以按Ctrl-A + X退出qemu。
