+# acm32f0x0板级支持包
+
+## 1. 简介
+
+ACM32F4xx芯片是上海爱信诺航芯电子科技有限公司(后续简称上海航芯)一系列支持多种低功耗模式的通用MCU。包括如下硬件特性：
+
+|--------------------------|--------------------|
+|         硬件             |         描述       |
+| -------------------------|--------------------|
+|芯片型号                  | ACM32F4XX系列      |
+|CPU                       | ARM Cortex-M33     |
+|主频                      | 180MHz             |
+|片内SRAM                  | 192K               |
+|片内Flash                 | 512K               |
+|--------------------------|--------------------|
+
+具体型号及资源请参考上海航芯官方网站[ACM32F4](www.aisinochip.com/index.php/product/child1/id/219.html)。
+
+## 2. 编译说明
+
+推荐使用[env工具][1]，可以在console下进入到`bsp/acm32f4xx-nucleo`目录中，运行以下命令：
+
+`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。
+
+也可以通过`scons --target=mdk5`生成keil工程，再使用keil进行编译。
+
+## 3. 烧写及执行
+
+开发板的使用请参考上海航芯官方网站相应型号的[开发工具](www.aisinochip.com/index.php/product/detail/id/25.html)。
+
+### 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：
+
+## 4. 驱动支持情况及计划
+
+| **片上外设**  | **支持情况** |               **备注**                |
+| ------------- | ------------ | ------------------------------------- |
+| GPIO          |     支持     | PA0, PA1... PF4 ---> PIN: 0, 1...83  |
+| UART          |     支持     |              UART1/UART2              |
+| LED           |     支持     |              LED1                     |

+;*                      - Set the initial SP
+;*                      - Set the initial PC == _iar_program_start,
+;*                      - Set the vector table entries with the exceptions ISR
+;*                        address.
+;*                      - Branches to main in the C library (which eventually
+;*                        calls main()).
+;*                      After Reset the Cortex-M33 processor is in Thread mode,
+;*                      priority is Privileged, and the Stack is set to Main.
