Kendryte K210环境搭建(Windows&Ubuntu)

Kendryte K210是RISC-V Dual Core 64bit, with FPU、QVGA@60fps/VGA@30fps的AIoT方向的芯片。同时也因为采用开源的指令集,使得它可能具有无限的潜力。

我们这次依旧没有使用公版,依旧是自家的板子,但是目前还没后续消息,也不能说太多,就忽略掉相关硬件信息吧,请见谅。

一、Ubuntu开发环境搭建:

1. 获取资料

获取资料当然是应该去官方的开发者资源中心,在里面可以看到资料还是比较详细的,同时也包括了工具链和SDK等等,同时开发文档有简中和繁中两种选择,这不得不说很舒服。
言归正传,我们需要下载什么呢?当然是toolchain、SDK和OpenOCD(On-Chip Debugger)了。
当然使用带有桌面的linux实体机或者虚拟机相对简单很多,如果命令行界面的话,最简单的操作步骤就是wget URL-link就可以了。

wget https://s3.cn-north-1.amazonaws.com.cn/dl.kendryte.com/documents/kendryte-openocd-0.1.3-ubuntu64.tar.gz
wget https://s3.cn-north-1.amazonaws.com.cn/dl.kendryte.com/documents/kendryte-toolchain-ubuntu-amd64-8.2.0-20190213.tar.gz
wget https://s3.cn-north-1.amazonaws.com.cn/dl.kendryte.com/documents/kendryte-freertos-sdk-0.7.0.zip
wget https://s3.cn-north-1.amazonaws.com.cn/dl.kendryte.com/documents/kendryte-standalone-sdk-0.5.6.zip

2. 安装toolchain

进入到下载文件保存的目录,将toolchain解压并放在指定目录。

hulk@hulk-test:~/kendryte210$ sudo tar -xvf kendryte-toolchain-ubuntu-amd64-8.2.0-20190213.tar.gz -C /opt/

我这里面的下载目录就是~/kendryte210,然后使用tar配合-xvf-C来解压并放在/opt目录下面,这个路径是自己选择的。

hulk@hulk-test:~/kendryte210$ cd /opt/kendryte-toolchain/bin/
hulk@hulk-test:/opt/kendryte-toolchain/bin$ pwd
/opt/kendryte-toolchain/bin

我们这一步的目的是获取它的目录,然后要把它添加到系统的PATH里面,这样才能方便的使用

sudo vi /etc/profile

打开文件后,在文末添加一行

PATH="$PATH:/opt/kendryte-toolchain/bin"

然后保存退出并重载一下profile文件即可。

source /etc/profile

接下来就是验证一下到底有没有装好呢?利用自动补全功能即可,在命令行输入riscv64然后按积下TAB键,就可以看到一堆自动补全待选的内容,如果没有review上面的步骤。

3. 安装OpenOCD

继续回到我们之前的下载路径,然后解压OpenOCD,并进入。

hulk@hulk-test:~/kendryte210$ tar -xvf kendryte-openocd-0.1.3-ubuntu64.tar.gz
hulk@hulk-test:~/kendryte210$ cd ./kendryte-openocd/

对于这个不熟悉的东西,我们可以先看下它的Readme.txt,它里面就提到了我们如何快速开始。

==============
  Quickstart
==============

1. Install libusb-1.0 first if you do not have:

  sudo apt install libusb-dev -y

2. Run the following command in the `kendryte-openocd` directory(or `check_version.sh`):

  ./bin/openocd -v

and you will see two lines of words if it can work:

  Kendryte Open On-Chip Debugger For RISC-V v0.1.3 (20180912)
  Licensed under GNU GPL v2

我们就直接照着做就可以了。

4. 开始编译

解压SDK

hulk@hulk-test:~/kendryte210$ unzip kendryte-standalone-sdk-0.5.6.zip
hulk@hulk-test:~/kendryte210$ cd kendryte-standalone-sdk-0.5.6/
hulk@hulk-test:~/kendryte210/kendryte-standalone-sdk-0.5.6$ ls
CHANGELOG.md  cmake  CMakeLists.txt  kendryte-package.json  lds  lib  LICENSE  README.md  src

准备工作做完,就可以开始准备编译了。首先,我们应该先建立一个用于编译的文件夹。

mkdir build
cd build

生成makefile,因为我们之前已经配置了相关环境

hulk@hulk-test:~/kendryte210/kendryte-standalone-sdk-0.5.6/build$ cmake .. -DPROJ=hello_world
PROJ = hello_world

看到Makefile created.,就表示OK了。
最后就可以开始编译了,可以看到如下类似的编译画面:

二、Windows开发环境搭建:

1. 获取资料

获取资料当然是应该去官方的开发者资源中心,在里面可以看到资料还是比较详细的,同时也包括了工具链和SDK等等,同时开发文档有简中和繁中两种选择,这不得不说很舒服。
言归正传,我们需要下载什么呢?当然是toolchain、SDK和OpenOCD(On-Chip Debugger)了。
我们直接点击我们点击我们需要下载的包后面的下载按钮即可。

Kendryte K210 FreeRTOS SDK
Kendryte K210 Standalone SDK
Kendryte OpenOCD for win32
RISC-V 64bit toolchain for Kendryte K210_win32

2. 安装toolchain

进入到下载文件保存的目录,将toolchain解压并放在指定目录。我把toolchain放在了E盘里面单独的一个文件夹E:\Kendryte210\kendryte-toolchain,并且进入bin文件夹,然后复制当前的目录路径,然后打开Windows的环境变量设置,将这个路径添加进去。
PATH

这里面一定要根据你的实际存放目录来确定,并且后面一定不能删除,切记。

3. 开始编译

首先在Windows下面编译,要先安装Cmake,我们可以到Cmake官网去下载。然后一步一步安装就好了。
解压SDK,可以把SDK和刚才的toolchain放在一个目录下面E:\Kendryte210\kendryte-standalone-sdk-0.5.6,然后进去这个目录,我们可以按住shift+右键,打开powershell,也可以向我一样安装一个cmder,因为这个比powershell要看着舒服一些,具体用法可以百度,也可以等我后面介绍。
接下来就是创建编译需要用到的makefile

E:\Kendryte210\kendryte-standalone-sdk-0.5.6
$ mkdir build
E:\Kendryte210\kendryte-standalone-sdk-0.5.6
$ cd build
E:\Kendryte210\kendryte-standalone-sdk-0.5.6\build

Makefile created.


-- Configuring done
-- Generating done
-- Build files have been written to: E:/Kendryte210/kendryte-standalone-sdk-0.5.6/build

看到Makefile created.就表示成功创建了makefile文件。同时可以在文件夹里面看到build目录下面生成了很多文件。
PATH

现在就可以开始编译代码了。在刚才的comder里面,我们输入mingw32-make,就可以开始编译了。

E:\Kendryte210\kendryte-standalone-sdk-0.5.6\build

到这里Ubuntu与Windows两大常用系统下面的环境就搭建好了,怎么选择完全可以看个人了。在使用桌面版Ubuntu时,完全可以时VS Code来完成写代码,同时在Ubuntu编译(迷信编译)。后面的文章将会位大家介绍下Kflash的简单用法。
