3.10.7 File Transfer Protocol Bootloader using SAM E54 Xplained Pro Development Boards

Download

Description

File Transfer Protocol (FTP) Bootloader demonstrates the use of an FTP server and client within a network, utilizing two SAM E54 Xplained Pro Evaluation Kits. One kit functions as the FTP server, while the other serves as the FTP client. Each kit is equipped with its own file system media. The SD card on the IO1 Xpro board serves as the storage medium for the file system, facilitating file transfers between the client and server boards. This application primarily focuses on the FTP network, where the client logs into the server to download the application binary file for loading the application.

Modules/Technology Used

Hardware Used

Software/Tools Used

This project has been verified to work with the following versions of software tools:

Refer Server Project Manifest, Client Project Manifest present in harmony-manifest-success.yml under the project folder same54_ftp_server or same54_ftp_client/firmware/src/config/sam_e54_xpro

  • Refer the Release Notes to know the MPLAB X IDE and MCC Plugin version.
  • Any Serial Terminal application, such as Tera Term terminal application.
  • Windows command prompt

Because Microchip regularly update tools, occasionally issue(s) could be discovered while using the newer versions of the tools. If the project does not seem to work and version incompatibility is suspected, It is recommended to double-check and use the same versions that the project was tested with.

To download original version of MPLAB Harmony v3 packages, refer to document How to Use the MPLAB Harmony v3 Project Manifest Feature (DS90003305)

Setup

  • Attach the IO1 Xpro board to the EXT1 of the SAME54 Xplained Pro Evaluation Kits.
  • Insert the Micro SD card into the Micro SD card slot on the IO1 Xpro boards. Ensure that the SD Card in the FTP Server contains the binary (*same54_ftp_server\utilities\test.bin) to be downloaded by the FTP Client.
  • Connect the micro-USB cable from the computer to the DEBUG USB connector on the SAM E54 Xplained Pro Evaluation Kits.
  • Connect the RJ45 ports of both SAM E54 Xplained Pro Evaluation Kits through the RJ45 cable, as shown in the following figure.

Programming hex file

The pre-built hex file can be programmed by following the below steps.

Steps to program the hex file:
  • Open MPLAB X IDE
  • Close all existing projects in IDE, if any project is opened.
  • Go to File -> Import -> Hex/ELF File.
  • In the Import Image File window,
    1. Create Prebuilt Project,
      • Click the Browse button to select the prebuilt hex file.
      • Select Device as ATSAME54P20A.
      • Ensure the proper tool is selected under Hardware Tool and click on Next button.
    2. Select Project Name and Folder,
      • Select appropriate project name and folder and click on Finish button
  • In MPLAB X IDE, click on Make and Program Device button to program the device.
  • Follow the steps in Running the Demo section below.

Programming/Debugging Application Project

  • Open the project(same54_ftp_server/firmware/ftp_client_sam_e54_xpro.X and same54_ftp_client/firmware/ftp_client_sam_e54_xpro.X) in MPLAB X IDE
  • Ensure SAM E54 Xplained Pro is selected as hardware tool to program/debug the application
  • Build the code and program the devices by clicking on the Make and Program button in MPLAB X IDE tool bar
  • Follow the steps in Running the Demo section below

Running the Demo

FTP Server:
  • From a terminal window application (such as Tera Term), connect to the COM port enumerated by SAM E54 Xplained Pro evaluation kit.
  • Restart the application (i.e reset the SAM E54 Xplained Pro Evaluation Kit)
FTP Client:
  • From a terminal window application (such as Tera Term), connect to the COM port enumerated by SAM E54 Xplained Pro evaluation kit.
  • Restart the application (i.e reset the SAM E54 Xplained Pro Evaluation Kit)
  • The IP address will be displayed on the terminal once it is ready. The user can connect to the FTP server
    • Type ftpc connect <host_ip_address>
  • Upon successful connection, enter the login details
    • Type ftpc login <username> <password>
  • Once logged in, use ftpc get command to download a binary from the server
    • Type ftpc get -a test.bin
  • After the binary is successfully downloaded it can be flashed to the MCU by using the boot command.
  • MCU is reset after the programming is complete and test application (LED Toggle) code starts executing.

Output

  • Once FTP server and client applications are programmed in the SAM E54 Xplained Pro Evaluation Kits, The initialization status of the TCP/IP stack is seen in the tera term window, the file system mounting status and GMAC IP address are listed in tera term console.
FTP Server:

FTP Client:

Note: Make sure the tera term baud rate to be 115200 for seeing the output properly.
