1.1.5 SAM E54 Xplained Pro Evaluation Kit: Building and Running the UDP Bootloader applications

Downloading and building the application

To clone or download this application from Github,go to the main page of this repository and then click Clone button to clone this repo or download as zip file. This content can also be download using content manager by following these instructions

Path of the application within the repository is apps/udp_bootloader/

To build the application, refer to the following table and open the project using its IDE.

Setting up SAM E54 Xplained Pro Evaluation Kit

  • Connect the Debug USB port on the board to the computer using a micro USB cable

  • Establish a connection between Host PC and the device through the RJ45 Ethernet connector using an Ethernet cable

Running the Application

  1. Open the test application project test_app/firmware/sam_e54_xpro.X in the IDE

  2. Build the project to generate the binary (Do not program the binary)

  3. Open the bootloader project bootloader/firmware/sam_e54_xpro.X in the IDE

  4. Build and program the application using the IDE

  5. LED0 will be Turned On once programming is completed and bootloader starts running

  6. Open the Terminal application (Ex.:Tera Term) on the computer to get test application messages through UART once bootloaded

  7. Configure the serial port settings as follows:

    • Baud : 115200

    • Data : 8 Bits

    • Parity : None

    • Stop : 1 Bit

    • Flow Control : None

  8. Configure the Host PC for setting up IP Address to communicate with the device

    • Go to Control Panel/Network and Internet/Network Connections

    • Open Ethernet properties

      ethernetProperties

    • Double Click on Internet Protocol Version 4 (TCP/IPv4)

      ethernetProperties

    • Configure the IP Address as shown below

      • IP address : 192.168.1.12

      • Subnet Mask : 255.255.255.0

      ethernetProperties

  9. Launch the Unified Host application from below path

    • <harmony3_path>/bootloader/tools/UnifiedHost-*/UnifiedHost-*.jar

  10. Configure the Unified host application

    • Select the Device architecture and Protocol as shown below

      hostConfig

    • Click on configure button to configure UDP port Number and IP Address

      hostUSBSetting

    • Load the test application hex file to be programmed using below option

      • <harmony3_path>/bootloader_apps_ethernet/apps/udp_bootloader/test_app/firmware/sam_e54_xpro.X/dist/sam_e54_xpro/production/sam_e54_xpro.X.production.hex

      hostLoadHex

    • Open the Console window of the host application to view application bootloading sequence

      hostToolsConsole

  11. Click on Program Device button to program the loaded test application hex file on to the device

    hostProgramDevice

  12. Following snapshot shows output of successfully programming the test application

    hostSuccess

  13. If above step is successful then LED0 should start blinking and you should see below output on the console

    output

  14. Press and hold the Switch SW0 to trigger Bootloader from test application and you should see below output

    output

  15. Repeat Steps 11-13 once and jump to Step-16

    • This step is to verify that bootloader is running after triggering bootloader from test application in Step 14

  16. Press and hold the Switch SW0 and then press Reset button or Power cycle the device to force trigger bootloader at startup

  17. Repeat Steps 11-13 once

    • This step is to verify whether bootloader is triggered by switch press at reset
