## Introduction
|
|||
|
|
|
|||
|
|
This document records the execution instruction of the BSP (board support package) provided by the RT-Thread development team for the NXP i. MX RT1020 EVK development board.
|
|||
|
|
|

|
- Advanced Features
|

|
|
|

|
|
By reading the Quickly Get Started section developers can quickly get their hands on this BSP and run RT-Thread on the board. More advanced features will be introduced in the Advanced Features section to help developers take advantage of RT-Thread to drive more on-board resources.

## Board Resources Introduction
|
|||
|
|
|
|||
|
|
The i.MX RT1020 EVK is a 2-layer low-cost through-hole USB-powered PCB. At its heart lies the i.MX RT1020 crossover MCU in LQFP144 package, featuring NXP’s advanced implementation of the Arm® Cortex®-M7 core. This core operates at speeds up to 500 MHz to provide high CPU performance and excellent real-time response.

## Execution Instruction
|
|||
|
|
|
|||
|
|
### Quickly Get Started
|
|||
|
|
|
|||
|
|
This BSP provides MDK 5 and IAR projects for developers. Here's an example of the IAR 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.eww file, to open the IAR project, compile and download the project to the board.
|
|||
|
|
|
|||
|
|
> By default, the project uses the CMSIS-DAP to download the program, when the CMSIS-DAP connects the board, clicking the download button can download the program to the board.
|
|||
|
|
|
|||
|
|
### **Running Results**
|
|||
|
|
|
|||
|
|
Once the project is successfully downloaded, the system runs automatically. The green LED on the board will flash periodically.
|
|||
|
|
|
|||
|
|
Connect the serial port of the board to the PC, communicate with it via a serial terminal tool(115200-8-1-N). Reset the board and the startup information of RT-Thread will be observed:

|
## **Advanced Features**
|
|||
|
|
|
|||
|
|
This BSP only enables GPIO and serial port 1 by default. If you need more advanced features, you need to configure the BSP with RT-Thread [Env tools](https://www.rt-thread.io/download.html?download=Env), as follows:
|
|||
|
|
1. Open the env tool under BSP;
|
|||
|
|
2. Enter menuconfig command to configure the project, then save and exit;
|
|||
|
|
3. Enter pkgs --update command to update the package;
|
|||
|
|
4. Enter scons --target=mdk5/iar command to regenerate the project.
|
|||
