 5. 执行m编译, m distclean清理; 或者参考vela文档，顶层目录执行 ./build.sh vendor/allwinnertech/boards/r528/r528s3-evb4/configs/bootloader -e -Wno-error V=s -j32进行编译
 6. 执行pack打包
 
+二、[RV-Gemini-S1]R528开发板编译打包说明
+1. 下载源码
+2. Gemini SDK位于/vendor/allwinnertech目录下
+        SDK目录结构：
+        vendor/allwinnertech/
+        ├── apps/                 # 核心应用与 Demo (如 luncher_mini)
+        ├── boards/               # 板级支持包 (包含启动代码、引脚配置)
