Peripheral Condition
Each peripheral supporting condition for this BSP is as follows:
Instruction
-Get started
This BSP provides MDK4, MDK5, and IAR projects for developers and it supports the GCC development environment. Here's an example of the MDK5 development environment, to introduce how to run the system.
-Hardware connection
Use a USB cable to connect the development board to the PC and turn on the power switch.
-Compile and Download
Double-click the project.uvprojx file, to open the MDK5 project, compile and download the project to the board.
By default, the executable file will be downloaded to the board by the simulator, which is connected to PC via the USB cable.
-Running Results
Once the project is successfully downloaded, the system runs automatically.
Connect the serial port of the board to PC, communicate with it via a serial terminal tool (115200bps, 8N1). Restart the board and the startup information of RT-Thread will be observed:

Advanced Features
This BSP only enables GPIO and serial port 2 by default. If you need more advanced features such as SPI, I2C, you need to configure the BSP with ENV tools, as follows:
- Open the env tool under BSP.
- Enter menuconfig command to configure the project, then save and exit.
- Enter pkgs --update command to update the package.
- Enter scons --target=mdk4/mdk5/iar command to regenerate the project.
