1. 开箱打开快递，发现Lichee RV非常mini，出乎我的想象。上个对比图，大家看看。

这是一个全志D1（现在官网上叫D1-H）芯片的低成本核心板。sipeed出品，官网名称叫做Lichee RV哪吒计算条，可以搭配Lichee RV HDMI Dock底板或者Lichee RV 86 Panel底板。
Lichee RV哪吒计算条的主要特性：

- 主控：全志D1H，平头哥玄铁C906内核，1GHz
- 内存：512MB ddr3
- 存储：TF卡启动
- 显示：预留一个小尺寸spi lcd的fpc排座，官方说是1.14英寸135x240的液晶屏。
- 接口：1）USB-OTG接口，2）2.54 4PIN系统串口,3)通过双M.2 B-Key金手指连接器，预留出67x2PIN
- 尺寸：46x25mm
以上是核心板的主要接口和器件。

2 D1-H介绍
2.1 简介
D1-H 是全志科技首款基于RISC-V指令集的芯片，集成了阿里平头哥64位C906核心，支持RVV，1GHz+主频，可支持Linux、RTOS等系统。同时支持最高4K的H.265/H.264解码，内置一颗HiFi4 DSP，最高可外接2GB DDR3，可以应用于智慧城市、智能汽车、智能商显、智能家电、智能办公和科研教育等多个领域。

2.2 芯片框图

系统框图：

除系统框图外，官方还提供了一个多媒体解码的解决方案系统图：

从上面两幅框图看，全志给D1-H芯片搭载了丰富的多媒体类外设，这也是全志之前产品主要的应用场景。
与之前的产品主要区别在于内核，D1-H采用的是RISC-V指令集的玄铁C906，我想这应该也是把这个核心板起名叫哪吒的原因吧。

3 系统烧录
D1-H的开发方式，有三种可以选：
1）debian镜像，新手建议选这个
2）tina镜像，熟悉的高手可以选这个，全志主推这个系统。基于openwrt魔改而来，全志的很多芯片都支持这个系统。
3) waft，这个是阿里云推出的东东，做前端的建议选这个。是一个面向 AIoT 的高性能应用研发框架，Waft 基于 WebAssembly 和自研的渲染引擎技术打造，适用于智能终端的软件应用研发场景。

考虑后面自己买个Lichee HDMI Dock底板，这里先选择LicheeRV_Debian_dock_hdmi_8723ds.img进行测试。

烧录软件：PhoenixCard
硬件：>=16G的tf卡一张，以及一个tf卡读卡器。

烧录过程比较简单：
1）点“固件”按钮选择要烧录的固件；
2）制作卡的种类选择“启动卡”；
3）从列表里选择你的tf卡；
4）点“烧卡”。
然后就会向下面图片一样：

注意：在状态显示40%的时候，虽然进度条不动了，输出信息栏也没有输出内容了，请千万不要动！！！

要一直等它自己进行完，时间会稍微长一点。
直到输出栏出现如下各种操作“完成”，表示烧录完成：

4 启动
把TF卡插到哪吒计算条，并连接号usb转ttl模块到pc。
pc打开串口调试工具，我这里用的是xshell。在串口调试工具打开相应的串口，波特率设置为115200，其他配置使用默认的就可以。
然后用type-c数据线供电（或用usb转ttl供5V电），在串口调试工具会输出启动信息：

Debian GNU/Linux 11 sipeed ttyS0



sipeed login:

从启动信息，可以看出整个启动过程，以及相关的信息。先启动了OpenSBI，然后启动uboot，然后kernel。
在uboot阶段，可以看到内存是512MB，CPU主频是1008Mhz。
在开始引导kernel是有这么一句话“Android's image name: d1-nezha”
从这里可以看出这个uboot之前是为一个Android系统设计的，现在被用来引导启动debian。
在linux启动过程有几个错误信息，咱们暂时先不管。

使用账号：sipeed，密码：licheepi登录系统后，出现如下信息：

5 解决“Message from syslogd。。。”问题
在shell下，系统不停地输出“Message from syslogd。。。”等信息，非常影响输入命令和观察输出内容。

解决方法：
1) 进入etc目录

复制

cd /etc

2) 打开rsyslog.conf文件。测试下了发现该系统自带nano工具。

复制

sudo nano rsyslog.conf

3)注释掉*.emerg *

复制

#*.emerg *

4）保存文件
先按ctrl+x，然后输入：y。
5）复位rsyslog服务

复制

systemctl restart rsysctl

shell中会显示如下内容，表示成功了：

从此，再也不用承受Message from syslogd。。。的骚扰了

6 简单测试
没有底板，先看看能做什么。
1）听说这个板子自带gcc
输入：

复制

gcc -v

显示：

复制

sipeed@sipeed:~$ gcc -v

Using built-in specs.

COLLECT_GCC=gcc

COLLECT_LTO_WRAPPER=/usr/lib/gcc/riscv64-linux-gnu/10/lto-wrapper

Target: riscv64-linux-gnu

Configured with: ../src/configure -v --with-pkgversion='Debian 10.2.1-6' --with-bugurl=file:///usr/share/doc/gcc-10/README.Bugs --enable-languages=c,ada,c++,go,d,fortran,objc,obj-c++,m2 --prefix=/usr --with-gcc-major-version-only --program-suffix=-10 --program-prefix=riscv64-linux-gnu- --enable-shared --enable-linker-build-id --libexecdir=/usr/lib --without-included-gettext --enable-threads=posix --libdir=/usr/lib --enable-nls --enable-clocale=gnu --enable-libstdcxx-debug --enable-libstdcxx-time=yes --with-default-libstdcxx-abi=new --enable-gnu-unique-object --disable-libitm --disable-libsanitizer --disable-libquadmath --disable-libquadmath-support --enable-plugin --enable-default-pie --with-system-zlib --enable-libphobos-checking=release --with-target-system-zlib=auto --enable-objc-gc=auto --enable-multiarch --disable-werror --disable-multilib --with-arch=rv64imafdc --with-abi=lp64d --enable-checking=release --build=riscv64-linux-gnu --host=riscv64-linux-gnu --target=riscv64-linux-gnu

Thread model: posix

Supported LTO compression algorithms: zlib zstd

gcc version 10.2.1 20210110 (Debian 10.2.1-6) 

sipeed@sipeed:~$

very good，有gcc可以用~~~

2）新建个目录

复制

mkdir hello

3）进入hello目录

复制

cd hello

4）新建hello.c

复制

nano hello.c

5) 输入代码

复制

#include<stdio.h>

int main()

{

    printf("Hello world!\n");

    return 0;

}

6）保存
按ctrl+x，输入：y。
7）编译

复制

gcc hello.c -o hello

8）看一下编译结果

复制

la -al

9）没问题的话就可以运行了

复制

./hello

查看编译结果和运行后输出内容如下：

好了，最简单的测试hello world成功了~~~
