SAM9X75 Curiosity Development Board - Introduction

Last modified by Microchip on 2024/10/03 10:14

In this training, we introduce the SAM9X75 Curiosity Development Board. The SAM9X75 Curiosity is designed for evaluating and prototyping with the high-performance, ultra-low power SAM9X75 ARM926EJ-S based microprocessor (MPU) running up to 800 MHz which can be used to develop embedded Linux® or Real-Time Operating System (RTOS) applications.

How Do I Write Images?

Demonstration images can be flashed onto a microSD memory card (of size 1 GB or higher) using the balenEtcher, a cross-platform utility program for writing image files onto storage media.

You can alternatively write an image to the onboard QSPI or NAND Flash memory. This is done using the SAM-BA® In-System Programmer (ISP) utility.

For more information on writing demonstration Linux images, see the "SAM9X75 Curiosity Development Board - Booting Demo Linux Image" page.

How Do I Debug?

JTAG

A JTAG interface to the SAM9X75-Curiosity is provided by 20-pin connector J34. This facilitates software development and debugging by connecting an external JTAG debugger such as the MPLAB PICkit™ 5 In-Circuit Debugger or J-32 Debug Probe .

Console Serial Port

A console serial port is available using the Debug Universal Asynchronous Receiver Transmitter (UART) port. The SAM9X75 Curiosity features a dedicated serial UART port (J35) (3.3 VDC TTL level) for communicating with the target console where you can:

  • View the kernel log
  • Query processes
  • Get information on various internal features of the system

See the "SAM9X75 Curiosity Development Board - Console Serial Communications" page for more information about the Linux console.
