cd byte-unixbench/UnixBench
./Run

应用层访问设备节点/dev/spidev0.0 /dev/spidev0.1

在Pi板设备上进行内核源代码编译

1.安装编译环境

apt install gcc make git python libncurses5-dev openssl libssl-dev build-essential pkg-config libc6-dev bison flex

1. 串口引脚说明

40PIN引脚，其中第8、10、14引脚信号分别对应TXD RXD GND，3.3V TTL电平，请连接到USB转TTL模块上。
如下图：

图中标号1连接GND
图中标号2连接USB串口模块TXD
图中标号3连接USB串口模块RXD

上图中40 pin排母功能定义如下表（图中左下为编号1，左上为编号2，右下为编号39，右上为编号40）

2. 串口工具putty

串口工具不限，附件仅作为参考使用
putty.zip

电脑串口工具设置串口波特率115200，8比特数据位，1个停止位，无校验，关闭流控。

使用MIPI DSI桥连接RGB屏（桥芯片TC358762或ICN6211）

RK3588集成DWC-MIPI-DSI2 ，它是一个实现 MIPI-DSI2 规范中定义的所有协议功能的控制器，兼容 D-PHY 和 C-PHY 的物理接口，支持两路的 Display Stream Compression (DSC) 数据传输，RK3588 有两个 DSI-2 控制器和两个独立的物理的 D/C-PHY，可以同时最多支持两路 MIPI 输出。

MIPI DSI基于差分信号传输，可以降低引脚数量和硬件设计复杂度，并保持良好的硬件兼容性。另外，基于MIPI DSI协议的IP还具备低功耗、低EMI的特性。

Hello from Docker!
This message shows that your installation appears to be working correctly.

To generate this message, Docker took the following steps:

1. The Docker client contacted the Docker daemon.
2. The Docker daemon pulled the "hello-world" image from the Docker Hub.
   (arm64v8)
3. The Docker daemon created a new container from that image which runs the
   executable that produces the output you are currently reading.
4. The Docker daemon streamed that output to the Docker client, which sent it
   to your terminal.

To try something more ambitious, you can run an Ubuntu container with:
$ docker run -it ubuntu bash
