+## 5.如何使用rv64ilp32工具链
+
+1. 工具链地址：https://github.com/ruyisdk/riscv-gnu-toolchain-rv64ilp32/tags
+
+2. 使用方法：
+
+   - 配置工具链路径
+
+   - 修改ABI参数为：-mabi=ilp32d
+
+   - 使用menuconfig使能下述选项:
+
+     ```shell
+     RT_USING_RV64ILP32
+     ```
+
+   - 使用menuconfig失能下述选项:
+
+     ```shell
+     RT_USING_POSIX_PIPE
+     RT_USING_POSIX_FS
+     RT_USING_DFS
+     ```
+
+3.  使用传统64位工具链与使用新32位工具链编译相同工程的固件大小对比：
+
+   传统64位工具链固件大小：
+
+   ```bash
+   Memory region         Used Size  Region Size  %age Used
+               SRAM:      225856 B        16 MB      1.35%

+    150907    3664   71268  225839   3722f rtthread.elf
+   ```
+
+   新32位工具链固件大小：
+
+   ```bash
+   Memory region         Used Size  Region Size  %age Used
+               SRAM:      209376 B        16 MB      1.25%
