T-HEAD Android

本项目为平头哥维护的生态开发板对安卓开源项目(AOSP)支持的仓库,主要包含了生态开发板的板级配置、外设HAL层、内核、u-boot和预编译组件支持,其余组件则可直接从上游AOSP仓库拉取。目前仓库中维护了基于曳影1520 SoC原型的BeagleV Ahead和Lichee Pi 4A开发板相关支持。

平头哥一直致力于RISC-V架构的安卓支持,开源了安卓10和安卓12两个版本的RISC-V架构支持,推动了RISC-V架构支持向安卓主线的合入并贡献了大量补丁提交;目前RISC-V架构已经得到了安卓开源项目的官方支持并作为Tire 1目标进行维护;后续平头哥也会持续贡献AOSP主线、上游三方项目、算法库优化、生态开发板、应用支持和RISC-V标准规范制定,帮助RISC-V的安卓支持在功能、性能、稳定性以及软硬件生态上进一步完善;也欢迎社区开发者参与到RISC-V的安卓支持和生态开发板支持的贡献。

生态开发板

BeagleV Ahead

BeagleV Ahead是推出的开发板产品,可以支持安卓、Debian、Ubuntu等多种操作系统;开发板集成了TH1520 SoC,包含4核运行于1.85G的玄铁C910处理器和4TOPS算力的NPU,内置GPU支持OpenGL ES、OpenCL和Vulkan,拥有USB、WiFI/BT、以太网、hdmi、mipi csi/dsi等多种设备接口,可用于视频会议一体机、人脸识别考勤门禁、医学成像等AI边缘计算应用场景。 beaglev

快速上手

在下载安卓开源项目源代码之前,请检查您的工作环境,建议使用具有至少250G磁盘空间、16GB+内存的Linux系统(推荐使用Ubuntu 20.04以上版本)的工作环境, 编译时间和主机的处理器核心数有关,建议使用有较多核心的主机。

将安卓开源项目(主线版本)和开发板支持源代码下载到工作目录:

mkdir riscv-android-src && cd riscv-android-src
repo init -u https://android.googlesource.com/platform/manifest -b master
git clone https://gitee.com/thead-android/local_manifests.git .repo/local_manifests -b thead-android-community
repo sync

BeagleV Ahead

完成下载后可以通过以下命令对系统进行构建

source build/envsetup.sh
lunch beaglev_ahead-userdebug
m -j

编译生成文件如下所示,可以将需要的文件拷贝供fastboot使用

$ ls out/target/product/beaglev_ahead/*img
out/target/product/beaglev_ahead/boot.img           out/target/product/beaglev_ahead/super_empty.img        out/target/product/beaglev_ahead/vendor_boot-debug.img

$ mkdir fastboot

beaglev_connect

图3. BeagleV Ahead 连接

开发板使用主要需要连接电源、串口、usb和显示:

  • 串口主要用于U-boot和内核中的命令交互,可通过底板上Debug的RX和TX连接,波特率为115200
  • USB Device接口主要用于fastboot和adb工具的连接
  • MIPI DSI/HDMI接口可以使用于连接屏幕显示UI界面

对系统进行完整烧写需要按住开发板的USB按键同时按复位键进入boot烧写模式。

之后使用fastboot对系统镜像进行烧写,adb和fastboot工具可以访问安卓开发者网站下载 https://developer.android.com/tools/releases/platform-tools

#烧录uboot并初始化boot环境变量
fastboot flash ram u-boot-with-spl.bin
fastboot reboot
fastboot flash uboot u-boot-with-spl.bin

#烧录各个分区
#在非boot烧写模式,可以在uboot的命令行中输入命令fastboot usb 0,单独烧录分区
fastboot flash bootpart bootpart.ext4
fastboot flash boot boot.img
fastboot flash vendor_boot vendor_boot.img
fastboot flash super super.img 
fastboot flash userdata userdata.img
fastboot flash vbmeta vbmeta.img
fastboot flash vbmeta_system vbmeta_system.img
 
#初始化metadata和misc分区
fastboot erase metadata 
fastboot erase misc

当完成烧写后重新复位上电进入系统启动模式,可以通过串口/ADB访问系统的命令行,并可通过触屏或外接HDMI显示系统图像界面进行交互。

Lichee Pi 4A EVB

完成下载后可以通过以下命令对系统进行构建

source build/envsetup.sh
#若使用Lichee Pi 4A开发板
