ROC-RK3568-PC
本文详细介绍 AxVisor + Linux 客户机、AxVisor + ArceOS 客户机 以及 AxVisor + Linux 客户机 和 ArceOS 客户机三种情况在 ROC-RK3568-PC 开发板上的构建、部署及运行!
开发环境
AxVisor 及 ROC-RK3568-PC 的 SDK 仅支持在 Linux 系统进中进行开发。本文中的构建及部署环境均采用 Ubuntu 24.04 系统作为开发环境。
-
ROC-RK3568-PC 的 SDK 本身不支持使用 Python3 来构建,需要稍加修改,文中会给出相关修改
-
如果不使用 Python3 环境,则需要手动安装 Python2 环境,因为很多新的 Linux 发行版本,例如, Ubuntu 24.04,默认已经不提供 Python2 的相关包了
构建
准备 AxVisor 镜像 + Linux 客户机镜像。
构建 Linux 客户机镜像
根据 ROC-RK3568-PC 开发板官方文档,构建 Linux 客户机镜像。
获取 SDK
下载 Firefly 提供的 SDK(整个文件夹)。下载的 SDK 实际上是由 repo
工具管理的一个仓库的源码的压缩包(一个 TAG 版本)及相关说明文档,需要解压之后再使用 repo
命令来恢复 SDK 的内容。
-
执行
chmod +x ./sdk_tools.sh
给脚本执行权限。 -
执行
mkdir ../firefly_rk3568_sdk
在当前压 缩包的上一级目录创建一个文件夹,存放实际 SDK 内容。 -
执行
./sdk_tools.sh --unpack -C ../firefly_rk3568_sdk
解压 SDK 仓库压缩包。其中实际上只有一个.repo
文件夹,需要进一步恢复 SDK 内容 -
使用
./sdk_tools.sh --sync -C ../firefly_rk3568_sdk
命令恢复 SDK 内容。也可以
cd ../firefly_rk3568_sdk
之后,手动执行如下命令:.repo/repo/repo sync -l
.repo/repo/repo start firefly --all注意: 如果当前构建环境系统中 Python 版本是 3.12 及以上,由于 SDK 中的
repo
版本比较旧,则需要进行修改才能适配 Python 的 3.10 及以上版本-
编辑
../firefly_rk3568_sdk/.repo/repo/main.py
中的如下所示的内容(imp
在 Python 的 3.4 版本中被标记为过时(由importlib
代替),并最终在 3.12 版本中被删除): -
新建
.repo/repo/formatter.py
文件(Python 3.10 及以上版本中formatter.py
过时已经被删除),并在其中输入以下内容:"""Generic output formatting.
Formatter objects transform an abstract flow of formatting events into
specific output events on writer objects. Formatters manage several stack
structures to allow various properties of a writer object to be changed and
restored; writers need not be able to handle relative changes nor any sort
of ``change back'' operation. Specific writer properties which may be
controlled via formatter objects are horizontal alignment, font, and left
margin indentations. A mechanism is provided which supports providing
arbitrary, non-exclusive style settings to a writer as well. Additional
interfaces facilitate formatting events which are not reversible, such as
paragraph separation.
Writer objects encapsulate device interfaces. Abstract devices, such as
file formats, are supported as well as physical devices. The provided
implementations all work with abstract devices. The interface makes
available mechanisms for setting the properties which formatter objects
manage and inserting data into the output.

更新 SDK。上面的 4 个步骤只需要执行一次,后续更新则都在
firefly_rk3568_sdk
目录中执行.repo/repo/repo sync -c --no-tags
即可,其中的build.sh
就是构建入口。
移植适配
ROC-RK3568-PC 的 SDK 不支持使用 Python3 来构建,如果当前构建环境系统中 Python 版本是 Python3 版本,则需要做如下修改:
-
修改
u-boot/make.sh
中的如下位置来取消对于 Python2 的检测
实际上,U-Boot 源码中还有大量基于 Python2 的脚本文件,在默认的构建中没有用的,因此这里不再继续修改
