Introduction

In this training topic, we introduce the SAMA7G54-EK Evaluation Kit (P/N: EV21H18A).  

SAMA7G54-EK Evaluation Kit

What can I do with the SAMA7G54-EK Evaluation Kit?

The SAMA7G54-EK is designed for evaluating and prototyping with the SAMA7G54, a high-performance, Arm® Cortex®-A7 CPU-based embedded microprocessor (MPU) running up to 1 GHz. The SAMA7G54-EK can be used to develop embedded Linux® or MPLAB® Harmony 3 Software Framework applications.

For information on Microchip's MPU offerings, visit the Microprocessors (MPUs) product page. 

What is the SAMA7G54-EK?

The SAMA7G54-EK is a multi-function demonstration and development platform featuring:

  • SAMA7G54 MPU
  • Mass Storage
  • Debugging
  • User Interface
  • Communications
  • Security
  • Audio
  • Expansion
  • Power Options

For more information, see: the SAMA7G54-EK - Features page.

Where can I get embedded Linux demo images?

Embedded Linux demonstration images for the SAMA7G54-EK are available on the Linux4SAM website. Images are available from three build automation systems:

How Do I Write Images?

Images can be written onto a SD Memory Card (of size 1 GB or higher) using the balenaEtcher utility program. BalenaEtcher is a cross-platform utility program used for writing image files onto storage media. For more information on writing demonstration Linux images, see:

You can alternatively write an image to the onboard NAND and NOR Flash memory. This is done using the SAM-BA In-System Programmer (ISP) utility. For more information, see:

Where Can I Get Source Code?

How Do I Debug?

J-Link Onboard (OB) + CDC – The Segger J-Link On-Board (OB) Debug Probe is included on the SAMA7G54-EK. The J-Link OB + CDC provides debugging/programming and a virtual COM port (CDC) from a single USB port. J-Link OB is fully supported and integrated into the MPLAB® X Integrated Development Environment (IDE).

Console Serial Port – A console serial port is available using the J-Link OB + CDC USB port (J24). With the target console where you can:

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

For more information see: SAMA7G54-EK – Console Serial Communications.

JTAG – A JTAG interface to the SAMA7G54-EK is provided by 20-pin connector J27. This facilitates software development and debugging by connecting an external JTAG debugger such as the J-32 Debug Probe or Segger J-Link BASE Debug Probe.

Serial Debug – A 2-pin Serial Wire Debug (SWD) port is provided by 6-pin connector J20. The two signals, SWDIO and SWCLK, are overlaid on the TMS and TCK pin allowing for bi-modal devices.

You will need a 6-pin, 5-volt Serial-to-USB adapter to connect the Serial Debug Port to a personal computer. If a 3-wire adapter is used, a jumper needs to be closed (shorted) between J20: VBUS_FTDI and J21: VDD_3V3
