本文介绍了如何搭建Amlogic A311D的开发环境，包括使用Ubuntu 18.04服务器或虚拟机作为源码编译平台，Windows 10用于烧录镜像，以及详细说明了toolchain编译链的配置，如GCC的版本选择和配置，涉及kernel和uboot的编译步骤。

1.、开发环境准备
1.1 Ubuntu 18.04 服务器或虚拟机 -- （用于源码编译）
建议内存32G以上

1.2 Windows 10电脑 -- （用于镜像的烧录）

1.3 A311D主控的开发板

2.toolchain编译链

2.1 需要用到的GCC

kernel：
gcc-linaro-6.3.1-2017.02-x86_64_aarch64-linux-gnu.tar
gcc-linaro-6.3.1-2017.02-x86_64_arm-linux-gnueabihf.tar.gz

uboot：

gcc-linaro-aarch64-none-elf-4.8-2013.11_linux.tar

2.2 uboot gcc配置

OTT-DS-AndP/bootloader/uboot-repo/bl33$ git diff ./
diff --git a/Makefile b/Makefile
old mode 100644
new mode 100755
index d42a459..973942a

3.编译方法

. build/envsetup.sh
lunch w400-userdebug
make otapackage 2>&1 | tee build.log
