ch32x033还可以利用PIOC加速，可能比SPI加速更合适，难点和创新点在PIOC的代码。隔壁网站ch32x035开发板试用俺以做个daplink并PIOC加速为试用出发点申领试用，然后被据.。。。然后我看了那些申请通过的试用方案，一言难尽>。

不过也好，先忙其它的，准备哪天等手里项目做差不多再到wch那买一块开发板来做软件方案。

xkrisc · 全志 SOC

此buildroot仓库也可以编译生成D1哪吒的镜像，这是完全利用主线中的支持了。只要把步骤中的

make licheepi_rv_defconfig

换成

make nezha_defconfig

我没哪吒开发板所以测试不了，理论上编译出的sdcard.img是能启动D1哪吒的。

如果想像Lichee RV Dock一样，用最新的opensbi, uboot, linux kernel，可按configs/licheepi_rv_defconfig中e设置定制这三者版本的地方改configs/nezha_defconfig文件

xkrisc · 全志 SOC

buildroot上游已经支持了D1 Nezha开发板，我为Lichee RV Dock做了如下适配开发：

A.uboot、opensbi使用了上游linux-sunxi社区的d1-wip分支，参见https://linux-sunxi.org/Allwinner_Nezha

B.linux kernel使用了上周日（2022年1月9日）release的linux-5.16 + linux-sunxi社区的d1-wip分支合并而成

C.为Lichee RV CM和其Dock添加了dts文件

D.buildroot添加了Lichee RV的board/相应目录和configs/目录下相应的defconfig文件

这样做的好处是，紧跟上游，代码清晰，关键软件部件几乎最新。

0.host上安装用于buildroot的必要软件包
此过程略，可自行搜索解决

1.获取代码：

git clone https://gitee.com/xhackerustc/buildroot.git -b d1-wip

2.用buildroot编译用于licheepi rv的img：

cd buildroot
make licheepi_rv_defconfig
make menuconfig   //上游buildroot默认uclibc且最小化编译，riscv平台俺建议用glibc，软件包方 面这一步选一些需要的软件包
make

3.编译完成后在output/images/sdcard.img就是要烧入sdcard的img

sudo dd if=output/images/sdcard.img of=/dev/sdX

目前sdcard，sdio、usb host、user按键、wdt都能工作。

注1：因使用的是mainline的linux内核，sipeed wiki中的RGB LED WS2812 进行花式点灯需要改下:
点红灯：

echo 88 > /sys/class/leds/rgb\:indicator/brightness;echo 255 0 0 > /sys/class/leds/rgb\:indicator/multi_intensity

接着上面点绿灯：

echo 0 255 0 > /sys/class/leds/rgb\:indicator/multi_intensity

点蓝灯以此类推。

注2：此系统镜像也适用于只有Lichee RV核心模块的用户，当然usb host、RGB LED肯定不能用的，所以最好启动后修改/boot/extlinux/extlinux.conf文件，把其中的:

devicetree /boot/sun20i-d1-licheepi-rv-dock.dtb

换成

devicetree /boot/sun20i-d1-licheepi-rv.dtb

这两dtb文件镜像都自带了

上电后串口log如下：从此log可以看到opensbi升级到了0.9版本，uboot升级到了uboot-2022.01-rc1, linuxe内核是最新的linux-5.16

memcpy性能数据表明它的cpu的L1 data cache很大可能是32KB，应该无L2以及L3，L1后应该就是内存了

xkrisc · 全志 SOC

烧录img是LicheeRV_Tina_dock_hdmi_8723ds.img，启动后发现cpu占用率很高，且来自sdio中断数特别高，所以做benchmark前需要把这两都降下来，否则benchmark结果受影响 --- 去/etc/rc.d/目录下把WAFT、SWUPdate、wpa_supplicant、mtp啥的都禁用，方法是把那些刚才提到的S开头的脚本改名，以bak开头。最终结果大概是系统中除内核线程外userspace只有一个shell，中断方面只有display中断比较频繁，大概60个中断/s（display常见就是60个中断/s)，除自己编译内核外目前还不知道怎么停掉display。

CPU部分：
Dhrystone: 2977963 Dhrystones/s, 因cpu频率1008MHZ，所以算得1.68 DMIPS/MHZ

coremark: 2323.960028 Iterations/s, 算得2.32 Iterations/s/MHZ

DDR部分：
D1 SoC的cpu支持RVV，所以测一下vector指令优化的memcpy以及glibc自带的std memcpy

这个性能结果不错RVV杠杠滴

注：这些数据都是linux下测得的虽然尽可能的去掉了操作系统系统影响因素但肯定比不过裸机环境的

xkrisc · 全志 SOC

俺长期从事linux内核和bsp开发，2021年一直口水D1哪吒开发板不过一直没舍得买，这次买了Lichee_RV_DOCK。开箱图就不贴了，烧Tina系统的img，用usb串口转接连EXTIO的GND、TX、RX引脚，串口可获得shell。下面做些官方wiki中https://wiki.sipeed.com/hardware/zh/lichee/RV/RV.html没有的小实验：

1.用户按键
在hdmi口边上下有两个键，一是RST，另一个即user按键

root@MaixLinux:/mnt/SDCARD# ./evtest
No device specified, trying to scan all of /dev/input/event*
Available devices:
/dev/input/event0: sunxi-keyboard
/dev/input/event1: audiocodec sunxi Audio Jack
/dev/input/event2: fts_ts
Select the device event number [0-2]: 0
Input driver version is 1.0.1
Input device ID: bus 0x19 vendor 0x1 product 0x1 version 0x100
Input device name: "sunxi-keyboard"
Supported events:
Event type 0 (EV_SYN)
Event type 1 (EV_KEY)
Event code 28 (KEY_ENTER)
Event code 114 (KEY_VOLUMEDOWN)
Event code 139 (KEY_MENU)
Event code 172 (KEY_HOMEPAGE)
Event code 352 (KEY_OK)
Properties:
Testing ... (interrupt to exit)
Event: time 6994.130779, type 1 (EV_KEY), code 352 (KEY_OK), value 1
Event: time 6994.130779, -------------- SYN_REPORT ------------
Event: time 6994.219394, type 1 (EV_KEY), code 352 (KEY_OK), value 0
Event: time 6994.219394, -------------- SYN_REPORT ------------

所以此用户按键默认键码是KEY_OK

2. rtc

root@MaixLinux:~# cat /sys/class/rtc/rtc0/time && sleep 10 && cat /sys/class/rtc/rtc0/time
01:58:24
01:58:33
root@MaixLinux:/mnt/SDCARD# ./rtctest

RTC Driver Test Example.

Counting 5 update (1/sec) interrupts from reading /dev/rtc0: 1 2 3 4 5
Again, from using select(2) on /dev/rtc: 1 2 3 4 5

Current RTC date/time is 1-1-1970, 01:52:04.
Alarm time now set to 01:52:09.
Waiting 5 seconds for alarm... okay. Alarm rang.

*** Test complete ***

3.watchdog
因watchdog被procd进程占用，故暂未测试wdt的功能，等用buildroot构建一个简单系统后可测

4.芯片里的温度sensor

root@MaixLinux:~# cat /sys/class/thermal/thermal_zone0/temp
30820

单位按linux惯例应该是毫摄氏度，所以这里报告温度是30.82度

5. sdcard和sdio的一些基本参数

root@MaixLinux:~# cat /sys/kernel/debug/mmc0/ios
clock: 50000000 Hz
vdd: 21 (3.3 ~ 3.4 V)
bus mode: 2 (push-pull)
chip select: 0 (don't care)
power mode: 2 (on)
bus width: 2 (4 bits)
timing spec: 2 (sd high-speed)
signal voltage: 0 (3.30 V)
driver type: 0 (driver type B)
root@MaixLinux:~# cat /sys/kernel/debug/mmc1/ios
clock: 50000000 Hz
vdd: 21 (3.3 ~ 3.4 V)
bus mode: 2 (push-pull)
chip select: 0 (don't care)
power mode: 2 (on)
bus width: 2 (4 bits)
timing spec: 2 (sd high-speed)
signal voltage: 0 (3.30 V)
driver type: 0 (driver type B)

所以sdcard也好，用于wifi的sdio也好，都是HS模式，时钟最高到50MHZ，工作电压3.3V，sd总线4位宽。

6. 各clock/pll基本情况

root@MaixLinux:~# cat /sys/kernel/debug/clk/clk_summary
...
pll-ddr0 2 2 0 1584000000 0 0 50
000
dram-clk 0 0 0 1584000000 0 0 50
000
...
pll-cpux 0 0 0 1008000000 0 0 50
000
riscv 0 0 0 1008000000 0 0 50
000
riscv-axi 0 0 0 504000000 0 0 50
000
pll-cpux-div 0 0 0 1008000000 0 0 50
000
...

这个列表好长，只把感兴趣的部分贴出。这表明那颗riscv cpu跑在1008MHZ频率下，DDR基础频率1584MHZ

注：evtest和rtctest是自己编译的程序，系统未自带。
