# NXP i. MX RT1170 EVK BSP(Board Support Package) Execution Instruction.
[中文页](README_zh.md) |
## 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 RT1170 EVK development board.
The document is covered in three parts:
- NXP i. MX RT1170 EVK Board Resources Introduction
- Quickly Get Started
- 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
i.MX RT1170 crossover MCUs are part of the EdgeVerse™ edge computing platform and are setting speed records at 1 GHz. This ground-breaking family combines superior computing power and multiple media capabilities with ease-of-use and real-time functionality. The dual core i.MX RT1170 MCU runs on the Arm® Cortex®-M7 core at 1 GHz and Arm Cortex-M4 at 400 MHz, while providing advanced security. The i.MX RT1170 MCU offers support over a wide temperature range and is designed for consumer, industrial and automotive markets.
## Peripheral Condition
Each peripheral supporting condition for this BSP is as follows:
| **On-board Peripherals** | **Support** | **Remark** |
| ------------------------ | ----------- | ------------------------------------- |
| USB | √ | |
| SPI Flash | √ | |
| Ethernet | √ | |
| **On-chip Peripherals** | **Support** | **Remark** |
| GPIO | √ | |
| SPI | √ | |
| I2C | √ | |
| SDIO | √ | |
| RTC | √ | |
| PWM | √ | |
| CAN | √ | |
## 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.
Then, the necessary libraries should be pulled; otherwise, the compilation will fail.
```bash
pkgs --update
```
#### 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.
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:
```
\ | /
- RT - Thread Operating System
/ | \ 4.1.1 build May 13 2022 11:37:59
2006 - 2022 Copyright by RT-Thread team
```
## **Advanced Features**
This BSP only enables 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.
