arm-fullhanv2-eabi-b3/ +``` + +使用下述命令将工具链的路径导出至环境变量（路径替换为用户工具链的路径）： + +```shell +export PATH=$PATH:/home/rtt/MC3302_RTT_SDK_V0.9.0_202504191346/Toolchain/arm-fullhanv2-eabi-b3/arm-fullhanv2-eabi-b3/bin +``` + +### 3.2 配置与编译 + +进入SDK源码路径，如下图所示： + +![](figures/1.src.png) + +源码路径下存在`envsetup.sh`脚本，运行下述命令配置SDK使用的平台与默认配置： + +```shell +./envsetup.sh +``` + +运行上述命令会出现下述两个选项，DEMO板的配置选择`2，2`，示例如下： + +![](figures/2.config.png) + +`mc3302_ddr_defconfig`文件可配置运行示例，该文件的相对路径如下： + +```shell +configs/mc3302_ddr_defconfig +``` + +打开上述文件，取消注释`CONFIG_APP_CONFIG_MAXLOAD_TEST=y`选项，注释`CONFIG_APP_CONFIG_SAMPLE_TEST=y`选项，该配置用于运行双屏显示示例。 + +![](figures/4.mconfig.png)- + +完成上述配置后，执行下述命令进行应用编译： + +```shell +cd bsp/rt-thread +make distclean +make mc3302_ddr_defconfig +make +``` + +示例编译结果如下： + +![](figures/3.complie.png) + +### 3.3 烧录软件配置 +

+![](figures/7.Download3.png) + +参考上图将前五个选项打勾，文件位置参考上图将SDK路径更换为用户的SDK路径。 + +完成上述配置，选择串口选项，串口端口根据用户平台选择，然后点击页面上的齿轮设置串口的参数，具体配置如下： + +![](figures/8.uart.png) + +### 3.4 烧录固件 + +首先将板子断电，将BOOT0管脚的跳帽接至1，如下图所示： + +![](figures/9.boot0.png) + +完成上述配置后点击下载选项，随后给板子上电开始下载固件: + +![](figures/10.Download4.png) + +完成烧录后断电将boot0的跳帽置为1后，重新上电即可启动。 + +### 3.5 运行测试命令 +
