IMX6ULL Pro Development Board Drivers

This repository provides drivers and example code for various components and peripherals of the i.MX 6ULL Pro development board.

Overview

The i.MX 6ULL Pro development board is an integrated single-chip solution suitable for various applications. This repository provides low-level drivers for the board's peripherals, including LED, Clock, Exception and Interrupt, DAC, SPI, I2C, UART, and LCD.

Development Environment

To build and deploy the drivers for the i.MX 6ULL Pro development board, set up a suitable development environment with the following tools:

About the Chip

The i.MX 6ULL is a low-power application processor from NXP, based on the ARM Cortex-A7 core.

Toolchain

The drivers can be compiled using the GNU Arm Embedded Toolchain. Install it by following these steps:

sudo apt-get update
sudo apt-get install gcc-arm-none-eabi

• IDE: ARM DS-5, Keil, or Eclipse.
• Compiler: ARM GCC or Keil ARMCC.
• Debugger: JTAG or SWD compatible with ARM Cortex-M processors.
• Operating System: Linux

Build System

The repository uses a Makefile-based build system. To build the project, you need make installed:

sudo apt-get install make

Emulator/Debugger

To debug the drivers, you can use OpenOCD and GDB:

sudo apt-get install openocd gdb-multiarch

Setup

1. Clone the Repository:

git clone git@github.com:Haibo-S/IMX6ULL-Pro-Drivers.git

2. Navigate into the repo:

cd IMX6ULL-Pro-Drivers

3. Build

make

4. Upload to Board

Use OpenOCD and GDB to upload and debug the code on the i.MX 6ULL Pro development board.

Quick Start:

For a quick start, try the following example code, which toggles an onboard LED:

#include "led.h"

int main(void) {
    led_init();
    while (1) {
        led_on(1);
        delay(500);
        led_off(1);
        delay(500);
    }
    return 0;
}
