一、获取SDK

请向代理或FAE获取全志V821的SDK，本博客使用的SDK是 V821_SDK_V1.1.tar

二、解压SDK

先确认压缩包里面是否包含了opt目录

tar tf V821_SDK_V1.1.tar | head -1

这个就是包含了opt目录，直接解压到根目录就可以

tar xvf V821_SDK_V1.1.tar -C /

三、安装基本环境

3.1 安装软件

本文环境：Ubuntu 24.04

sudo apt-get updatesudo apt-get install build-essential subversion git-core libncurses5-dev zlib1g-dev gawk flex quilt libssl-dev xsltproc libxml-parser-perl mercurial bzr ecj cvs unzip lib32z1 lib32z1-dev lib32stdc++6 libstdc++6 -y

对于Ubuntu 16.04以上版本，部分软件包已不再提供或者采用了其他的包，执行上述命令时， 安装失败的包可先忽略，进一步执行以下命令：

sudo apt-get install libc6:i386 libstdc++6:i386 lib32ncurses5 lib32z1

3.2 从仓库恢复SDK

cd /opt/V821_SDK_V1.1
.repo/repo/repo sync -l

3.2.1 ubuntu24.04 不支持python2

root@foxpi:/opt/V821_SDK_V1.1# .repo/repo/repo sync -l
warning: Python 3 support is currently experimental. YMMV.
Please use Python 2.6 - 2.7 instead.
Traceback (most recent call last):File "/opt/V821_SDK_V1.1/.repo/repo/main.py", line 19, in <module>import imp
ModuleNotFoundError: No module named 'imp'

3.2.2 不支持的原因

Python 2自2020年1月1日起停止维护，Ubuntu 22及以后版本官方仓库已移除Python 2相关包

Tips: 用ubuntu 16、18、20的就不用担心啦

3.2.3 下载安装python2

3.2.3.1 安装编译依赖

sudo apt update
sudo apt install -y build-essential wget libssl-dev libbz2-dev libreadline-dev libsqlite3-dev libncurses5-dev libncursesw5-dev libffi-dev zlib1g-dev

3.2.3.2 下载Python 2源码

cd /usr/src
sudo wget https://www.python.org/ftp/python/2.7.18/Python-2.7.18.tgz
sudo tar xzf Python-2.7.18.tgz
cd Python-2.7.18

3.2.3.3 编译安装

sudo ./configure
sudo make -j$(nproc)
sudo make altinstall
# 注意：使用make altinstall避免覆盖系统默认的python3命令。

3.2.3.4 验证安装

root@foxpi:/usr/src/Python-2.7.18# python2.7 --version
Python 2.7.18

3.2.3.5 创建软链接

查找当前路径

root@foxpi:/opt/V821_SDK_V1.1# whereis python
python: /usr/src/Python-2.7.18/python

创建链接

sudo ln -s /usr/local/bin/python2.7 /usr/bin/python

查看结果

root@foxpi:/opt/V821_SDK_V1.1# whereis python
python: /usr/bin/python /usr/src/Python-2.7.18/python

3.2.3.6 从本地仓库恢复SDK

root@foxpi:/opt/V821_SDK_V1.1# .repo/repo/repo sync -l

四、首次编译

• source build/envsetup.sh ：初始化Tina环境变量
• lunch 会提供方案选项以供选择
• make -j$(nproc) ：编译，其中-j后面的数字参数为编译用的线程数，可根据开发者编译用的PC实际情况选择。
• pack : 打包，将编译好的固件打包成一个.img格式的固件，固件路径 out/v821_linux_foxpi_uart0.img

4.1 创建自己的板级方案

4.1.1 初始化环境变量

foxpi@foxpi:/opt/V821_SDK_V1.1$ source build/envsetup.sh
NOTE: The SDK(/opt/V821_SDK_V1.1) was successfully loaded
load openwrt... ok
Please run lunch next for openwrt.
load bsp...ok

4.1.2 选择一个基本方案

创建自己的板级方案会在这个基础上进行修改

foxpi@foxpi:/opt/V821_SDK_V1.1$ lunchYou're building on LinuxLunch menu... pick a combo:1  v821-aiglass-tina2  v821-ipc-tina3  v821-perf2-tina4  v821-perf2_fastboot-tina5  v821-perf2b-tina6  v821-perf2b_fastboot-tina7  v821-ver1-tina
Which would you like?: 3

4.1.3 create_new_board

SDK提供便捷的方式创建板级档案 create_new_board

foxpi@foxpi:/opt/V821_SDK_V1.1$ create_new_board_______             _____             __        ___                   __

/_/ /_/_//_/\_,_/  \___/_/  \__/\_,_/\__/\__/ /____/\___/\_,_/_/  \_,_/-------------------------------------------------------------------------
Base on board name: v821-perf2-tina
Please input new board name (eg. custom_board): foxpi
Start generate new board: v821-foxpi-tina
-------------------------------------------------------------------------
Board foxpi now created. Please reload environment and lunch your new board:
source build/envsetup.sh && lunch

4.2 编译打包

然后按照下面顺序进行编译和打包

source build/envsetup.sh
lunch {刚才创建的序号}
make
pack

第一次编译建议单线程编译
make -j1 V=sc

以下为部分编译日志

foxpi@foxpi:/opt/V821_SDK_V1.1$ make
