# Kendryte K210板级支持包说明
|
||||
|
||||
## 1. 简介
|
||||
|
||||
Kendryte K210 是集成机器视觉与机器听觉能力的系统级芯片(SoC)。使用台积电 (TSMC) 超低功耗的 28 纳米先进制程，具有双核64位处理器，拥有较好的功耗性能，稳定性与可靠性。该方案力求零门槛开发，可在最短时效部署于用户的产品中，赋予产品人工智能。
|
||||
|
||||
Kendryte K210 定位于AI与IoT市场的SoC，同时是使用非常方便的MCU。
|
||||
|
||||
Kendryte中文含义为勘智，而勘智取自勘物探智。这颗芯片主要应用领域为物联网领域，在物联网领域进行开发，因此为勘物；这颗芯片主要提供的是人工智能解决方案，在人工智能领域探索，因此为探智。
|
||||
|
||||
* 具备机器视觉能力
|
||||
* 具备机器听觉能力
|
||||
* 更好的低功耗视觉处理速度与准确率
|
||||
* 具备卷积人工神经网络硬件加速器KPU，可高性能进行卷积人工神经网络运算
|
||||
* TSMC 28nm先进制程，温度范围-40°C到125°C，稳定可靠
|
||||
* 支持固件加密，难以使用普通方法破解
|
||||
* 独特的可编程IO阵列，使产品设计更加灵活
|
||||
* 低电压，与相同处理能力的系统相比具有更低功耗
|
||||
* 3.3V/1.8V双电压支持，无需电平转换，节约成本
|
||||
|
||||
芯片规格包括如下：
|
||||
|
||||
| 硬件 | 描述 |
|
||||
| -- | -- |
|
||||
|芯片型号| K210 |
|
||||
|CPU| 双核RV64GC |
|
||||
|主频| 400MHz |
|
||||
|片内SRAM| 8MB |
|
||||
| 外设 | 内嵌AES与SHA256算法加速器 |
|
||||
| | DVP、JTAG、OTP、FPIOA、GPIO、UART、SPI、RTC、I²S、I²C、WDT、Timer与PWM |
|
||||
|
||||
## 2. 编译说明
|
||||
|
||||
编译K210，需要先下载K210 BSP以及RT-Thread代码：
|
||||
|
||||
git clone https://github.com/BernardXiong/K210.git
|
||||
cd K210
|
||||
git submodule init
|
||||
git submodule update
|
||||
|
||||
git clone https://github.com/RT-Thread/rt-thread.git
|
||||
cd rt-thread
|
||||
git checkout -b dev-4.0.x origin/dev-4.0.x
|
||||
|
||||
注意，因为RT-Thread整体代码太庞大，所以并未把RT-Thread git repo以一个submodule方式加入到K210 BSP git repo中，
|
||||
而是需要把RT-Thread代码克隆到K210目录下，并切换到dev-4.0.x分支。
|
||||
|
||||
编译推荐使用[env工具][1]，可以在console下进入到`K210`目录中，运行以下命令：
|
||||
|
||||
set RTT_EXEC_PATH=your_toolchains
|
||||
scons
|
||||
|
||||
来编译这个板级支持包。如果编译正确无误，会产生rtthread.elf、rtthread.bin文件。其中rtthread.bin需要烧写到设备中进行运行。
|
||||
|
||||
## 3. 烧写及执行
|
||||
|
||||
连接好串口，然后使用[K-Flash](https://kendryte.com/downloads/)工具进行烧写bin文件。
|
||||
|
||||
|
||||
|
||||
### 3.1 运行结果
|
||||
|
||||
如果编译 & 烧写无误，当复位设备后，会在串口上看到RT-Thread的启动logo信息：
|
||||
|
||||
|
||||
|
||||

## 6. 注意事项
|
||||
|
||||
在进行系统menuconfig配置时，以下项是必选的
|
||||
|
||||
| 配置项 | 强制配置值 |
|
||||
| ----- | --------- |
|
||||
| Alignment size for CPU architecture data access | 8 |
|
||||
| The stack size of idle thread | > 1024 |
|
||||
| the device name for console | "uarths" |
|
||||
| Set main thread stack size | 4096 |
