使用IKAYAKI-SDK编译构建系统

1. IKAYAKI-SDK架构简介

1. 模块介绍

简称	全称	职责
SYS	System	实现 MI 系统初始化、内存缓冲池管理、各个模块之间数据流的管理
VDEC	Video Decoder	H264/H265/JPEG 视频解码器
DIVP	Deinterlace&Video Post Process Engine	DIVP Engine有两个主要的功能 ①对解码后数据进行格式转换 ②解码后数据进行缩放
VDISP	Vitrual Display	软件拼图
DISP	Display Engine	DISP对VDEC/DIVP 处理单元输出的图像做硬件拼图，并连同AO输出音频信号一起编码成HDMI/VGA/CVBS 输出信号的单元
VENC	Video Encoder	H264/H265/MotionJpeg编码器
AI	Audio Input Interface	I2S audio input采集单元
AO	Audio Output Interface	音频输出
GFX	Graphics Engine	Graphic Engine 提供对2D画图的基本硬件加速支援，降低CPU的负荷
FB	FrameBuffer	UI显示
HDMI	High Definition Multimedia Interface	HDMI/VGA标准输出

2. 软件架构

功能实现函数从上到下，分为MI API层，MI实现层，Hal硬件抽象层，Driver层和芯片硬件层。
SDK功能代码在Kernel层实现，减少从kernel到User mode来回调度，提高逻辑函数实现的效率。
对上层客户提供MI API的User Mode接口，用户层APP直接调用MI接口，即可调用到对应的MI功能。

3. SDK目录结构

目录	模块名	功能
project	board	PCB板信息存放路径
project	configs	预配置文件存放路径
project	image	产生镜像文件的材料库和镜像文件存放处
project	kbuild	kernel编译环境
project	release	目标池，存放对外头文件，库文件和内核模块以及第三方库
SDK	Verify/feature	验证文件夹，里面存放模块单元测试和特性测试文件
SDK	Verify/demo	整体功能测试demo

4. 内存管理

详细参考Memory Layout介绍。

通过mmap.ini预留的内存
支持mma管理module内存，各个module从mma预留的size中分配

5. 基本概念

数据流：各个MI Module 可以看成是一个纯数据处理单元，数据流推送由MI SYS内部统一调度。输入数据流表示该数据单元的input数据，输出数据流表示该处理单元处理过的output数据。
控制流：APP 对各个MI Module 数据处理过程进行参数控制的过程，比如设置MI_VDEC解码参数，启动停止MI_VDEC 通道，设置MI_VDEC通道输出端口之分辨率及format等
Channel（通道）
- 对于需要处理或者输出stream的MI模组，一个channel代表该MI 模组处理或者输出一路stream的分时复用的上下文（context）及相关控制流设定
- 对于可分时复用之模组如MI_VDEC, MI_DIVP, MI_DISP，可支援多个channel
Port（端口）
- Port分为2种，input port和output port。input port为channel输入数据流的位置，而output port则是channel输出数据流的位置。
- 一个channel可以有多个input port及多个output port.

2. 获取SDK工程

代码获取

使用浏览器打开链接 https://dongshanpi.cowtransfer.com/s/5c3c05deef7247 下载整个文件夹 IKAYAKI_SDK ，下载完成后可以看到里面包含了如下 6个压缩包文件。

arm-sigmastar-linux-uclibcgnueabihf-9.1.0.tar.xz
gcc-sigmastar-9.1.0-2020.07-x86_64_arm-linux-gnueabihf.tar.xz
boot-IKAYAKI_DLM00V015.tar.gz    
project-IKAYAKI_DLM00V015.tar.gz
kernel-IKAYAKI_DLM00V015.tar.gz  
sdk-IKAYAKI_DLM00V015.tar.gz

使用Filezila 或者samba 或拖拽等方式把这些文件拷贝到 Ubuntu系统家目录下。

拷贝之前可以先使用 mkdir DongshanPI-PicoW 创建一个板子的目录，之后再次创建一个 IKAYAKI_SDK 文件夹,如下命令中 $ 符号后的操作示例。

book@100ask.org:~$ mkdir DongshanPI-PicoW
book@100ask.org:~$ cd DongshanPI-PicoW/
book@100ask.org:~/DongshanPI-PicoW$ mkdir IKAYAKI_SDK
book@100ask.org:~/DongshanPI-PicoW$ cd IKAYAKI_SDK/
book@100ask.org:~/DongshanPI-PicoW/IKAYAKI_SDK$

最后我们将下载好的 6个压缩包文件拷贝至创建好的 IKAYAKI_SDK 文件夹。拷贝完成后如下所示

book@virtual-machine:~/DongshanPI-PicoW/IKAYAKI_SDK$ ls -lh
total 1.3G
-rwxr--r-- 1 book book  40M Sep  9  2022 arm-sigmastar-linux-uclibcgnueabihf-9.1.0.tar.xz

book@virtual-machine:~/DongshanPI-PicoW/IKAYAKI_SDK$

解压源码

接下来我们需要使用 tar 命令进行依次解压缩操作。

解压glibc工具链

book@virtual-machine:~/DongshanPI-PicoW/IKAYAKI_SDK$ tar -xvf  gcc-sigmastar-9.1.0-2020.07-x86_64_arm-linux-gnueabihf.tar.xz

解压bootloader

book@virtual-machine:~/DongshanPI-PicoW/IKAYAKI_SDK$ tar -xvf  boot-IKAYAKI_DLM00V015.tar.gz

解压kernel

book@virtual-machine:~/DongshanPI-PicoW/IKAYAKI_SDK$ tar -xvf  kernel-IKAYAKI_DLM00V015.tar.gz

解压sdk

book@virtual-machine:~/DongshanPI-PicoW/IKAYAKI_SDK$ tar -xvf  project-IKAYAKI_DLM00V015.tar.gz
book@virtual-machine:~/DongshanPI-PicoW/IKAYAKI_SDK$ tar -xvf  sdk-IKAYAKI_DLM00V015.tar.gz

解压后的所有目录,这里会发现 boot kernel project sdk 目录都没有了后面的 -IKAYAKI_DLM00V015 字样，这里请留意。

设置工具链

在上一步骤我们解压了 glibc交叉编译工具链，接下来需要设置一下环境变量，如下所示，首先进入到 gcc-sigmastar-9.1.0-2020.07-x86_64_arm-linux-gnueabihf交叉编译工具链路径，之后继续进入到 bin路径，使用pwd命令显示当前的完整路径，/home/book/DongshanPI-PicoW/IKAYAKI_SDK/gcc-sigmastar-9.1.0-2020.07-x86_64_arm-linux-gnueabihf/bin之后通过设置 ~/.bashrc 来配置环境变量参数

book@virtual-machine:~/DongshanPI-PicoW/IKAYAKI_SDK$ cd gcc-sigmastar-9.1.0-2020.07-x86_64_arm-linux-gnueabihf/
book@virtual-machine:~/DongshanPI-PicoW/IKAYAKI_SDK/gcc-sigmastar-9.1.0-2020.07-x86_64_arm-linux-gnueabihf$ cd bin/

book@virtual-machine:~/DongshanPI-PicoW/IKAYAKI_SDK/gcc-sigmastar-9.1.0-2020.07-x86_64_arm-linux-gnueabihf/bin$

设置临时环境变量

此方式只在当前终端下有效，如果重新打开一个终端，需要重新设置执行这些配置

export ARCH=arm
export CROSS_COMPILE=arm-linux-gnueabihf-
export PATH=$PATH:/home/book/DongshanPI-PicoW/IKAYAKI_SDK/gcc-sigmastar-9.1.0-2020.07-x86_64_arm-linux-gnueabihf/bin

book@virtual-machine:~$ export ARCH=arm
book@virtual-machine:~$ export CROSS_COMPILE=arm-linux-gnueabihf-
book@virtual-machine:~$ export PATH=$PATH:/home/book/DongshanPI-PicoW/IKAYAKI_SDK/gcc-sigmastar-9.1.0-2020.07-x86_64_arm-linux-gnueabihf/bin

设置永久环境变量

使用vim gedit nano等文本编辑器工具打开 ~/.bashrc 在最底部添加如下三行环境配置，即可永久生效。

export ARCH=arm
export CROSS_COMPILE=arm-linux-gnueabihf-
export PATH=$PATH:/home/book/DongshanPI-PicoW/IKAYAKI_SDK/gcc-sigmastar-9.1.0-2020.07-x86_64_arm-linux-gnueabihf/bin

修改默认sh

如果默认是sh，需要将sh改成 bash 。

book@virtual-machine:~$ sudo rm /bin/sh
book@virtual-machine:~$ sudo ln –s /bin/bash /bin/sh

3. SDK开发包编译步骤

如下分别提到了“编译boot”，“编译kernel”，“编译sdk”，boot已经默认编译好放到project路径，因此刚开始验证的时候，可以直接跳过“编译boot”和“编译kernel”，直接从“编译sdk”（kernel的编译已经集成到编译sdk里面，默认会编译kernel）开始编译出来整个image，就可以烧写、验证了。

注意：不同的芯片原厂都有不同的开发框架和方式，请使用的同学不要纠结这个问题，按照文档操作就可以。注意：不同的芯片原厂都有不同的开发框架和方式，请使用的同学不要纠结这个问题，按照文档操作就可以。注意：不同的芯片原厂都有不同的开发框架和方式，请使用的同学不要纠结这个问题，按照文档操作就可以。

编译bootloader

检查环境变量是否正确

在终端下输入 arm-linux-gnueabihf-gcc -v来验证是否正确，如果正常会打印出 gcc的版本信息等,如下所示，如果没有，请回到上一步配置。

book@virtual-machine:~$ arm-linux-gnueabihf-gcc -v
Using built-in specs.
COLLECT_GCC=arm-linux-gnueabihf-gcc
COLLECT_LTO_WRAPPER=/home/book/DongshanPI-PicoW/IKAYAKI_SDK/gcc-sigmastar-9.1.0-2020.07-x86_64_arm-linux-gnueabihf/bin/../libexec/gcc/arm-linux-gnueabihf/9.1.0/lto-wrapper

Thread model: posix
gcc version 9.1.0 (GCC)

之后再重新在终端配置一下 ARCH CROSS_COMPILE 两个环境变量,设置完成后就可以继续进行后续的开发操作了

export ARCH=arm
export CROSS_COMPILE=arm-linux-gnueabihf-

接下来进入到 boot 目录内，这个就是bootloader源码目录，进入目录后，我们就可以在这里面编译 bootloader 镜像了

book@virtual-machine:~/DongshanPI-PicoW/IKAYAKI_SDK$ cd boot/
book@virtual-machine:~/DongshanPI-PicoW/IKAYAKI_SDK/boot$ ls

编译bootloader

在开始编译之前我们要先确认配置文件名称，如下所示 DongshanPI-PicoW 默认的镜像配置文件名称为 pioneer3_spinand_defconfig

Flash Type	Other	Defconfig
SPI-NAND	基本	pioneer3_spinand_defconfig

接下来使用 make pioneer3_spinand_defconfig 来指定配置文件并开始编译，配置完成后输入 make 命令即可开始编译，操作步骤如下所示，请留意 $ 符号后面才是命令。

book@virtual-machine:~/DongshanPI-PicoW/IKAYAKI_SDK/boot$

编译完成的镜像是 u-boot_spinand.xz.img.bin 这个是最终可以用来烧录的镜像文件。

一般情况下，没法单独只烧写一个 u-boot镜像，所以最好是参考下面步骤拷贝到 project 目录，做成一个完整的镜像使用烧写工具烧写。

拷贝打包使用

把编译出来的 u-boot_spinand.xz.img.bin，替换到project/board/p3/boot/spinand/uboot/u-boot_spinand.xz.img.bin，重新编译project即可生产一个完整系统镜像

book@virtual-machine:~/DongshanPI-PicoW/IKAYAKI_SDK/boot$ cp u-boot_spinand.xz.img.bin ../project/board/p3/boot/spinand/uboot/

编译kernel

编译SDK会默认编译kernel，和SSD201/SSD202不同。因此建议修改相关kernel之后，直接在project下编译，会默认编译kernel的内容，并且不需要手动release到project下的路径。

检查环境变量是否正确

在终端下输入 arm-linux-gnueabihf-gcc -v来验证是否正确，如果正常会打印出 gcc的版本信息等,如下所示，如果没有，请回到上一步配置。

之后再重新在终端配置一下 ARCH CROSS_COMPILE 两个环境变量,设置完成后就可以继续进行后续的开发操作了

export ARCH=arm
export CROSS_COMPILE=arm-linux-gnueabihf-

接下来进入到 boot 目录内，这个就是bootloader源码目录，进入目录后，我们就可以在这里面编译 bootloader 镜像了

编译LinuxKernel

在开始编译之前我们要先确认配置文件名称，如下所示 DongshanPI-PicoW 默认的镜像配置文件名称为 pioneer3_ssc021a_s01a_spinand_demo_defconfig

Chip	Packaging	Memory	Flash Type	Toolchain	Other	Defconfig
SSD210	QFN68	64M	SPI-NAND	glibc	不带sensor	make pioneer3_ssc021a_s01a_spinand_demo_defconfig

接下来使用 make pioneer3_ssc021a_s01a_spinand_demo_defconfig 来指定配置文件并开始编译，配置完成后输入 make 命令即可开始编译，操作步骤如下所示，请留意 $ 符号后面才是命令。

编译完成的镜像是 arch/arm/boot/uImage.xz 这个是最终可以用来启动的内核镜像。这个是设备树文件 arch/arm/boot/dts/pioneer3-ssc021a-s01a-demo.dtb

如果kernel 有新增kernel modules需要将相应的module添加到kernel_mod_list/kernel_mod_list_late（kernel_mod_list_late里的ko会在mi module之后装载）修改路径：project/kbuild/customize/$(KERNEL_VERSION)/$(CHIP)/$(PRODUCT)/kernel_mod_list

注意：如果编译kernel时提示 dtb打包错误，则需要参考 https://github.com/DongshanPI/Sigmastar-Linux/commit/dfbfa30b5dd564a05812d5ecd967a53e51749304 修改对应的源码，这个问题是SDK不兼容问题导致。

编译SDK

默认编译sdk时，会先build kernel，第一次编译通过make clean;make image -j8命令全部编译，后续如果不需要build kernel可以用make image-fast代替make image。

检查环境变量是否正确

在终端下输入 arm-linux-gnueabihf-gcc -v来验证是否正确，如果正常会打印出 gcc的版本信息等,如下所示，如果没有，请回到上一步配置。

打包错误解决

vim image/makefiletools/script/fwfs_pack.py
修改 120行 str(image_size) 为 str(int(image_size))

4.拷贝镜像烧写编译完成后生成的image在project/image/output/images目录，我们把这些所有的镜像文件拷贝到默认的系统镜像文件夹内，替换掉原来的，重启开发板进入烧录模式就可以更新系统为你最新编译出来的系统镜像了。
