Setting up PIC32WM BZ6 Curiosity Evaluation Board

  • is used as Host Development kit

  • is used as Target Development kit

    can_bootloader_host_target_connection

  • Insert ATA6563 click board in the mikroBUS 1 connector of PIC32WM BZ6 Curiosity Evaluation Board.

  • Connect SAM E54 Xplained Pro Evaluation Kit to PIC32WM BZ6 Curiosity Evaluation Board as per the pin connections shown below

  • Connect the CANL on CAN Header of the Host development kit to the PIN 2 on ATA6563 click board of the Target development kit

  • Connect the CANH on CAN Header of the Host development kit to the PIN 7 on ATA6563 click board of the Target development kit

  • Connect a ground wire between the Host development kit and Target development kit

  • Connect the Debug USB port on the Host development kit to the computer using a micro USB cable

  • Connect the Debug USB port on the Target development kit to the computer using a micro USB cable

Building and Configuring CAN Host Applications

Using CAN NVM Host application to send the application binary to Target development kit

host_app_nvm_setup

If the NVM Host Development Kit being used is other than then follow the steps mentioned in Configuring NVM Host application project

  1. Open the NVM host application project host_app_nvm/firmware/sam_e54_xpro.X in the IDE

    • If a NVM host application project of different development kit is used then open that project in the IDE

  2. Build and program the NVM host application using the IDE on to the Host development kit

    • The prebuilt test application image available under host_app_nvm/firmware/src/test_app_images/image_pattern_hex_pic32wm_bz6_curiosity.h will be programmed on to the Target development kit with default host_app_nvm project configuration

  3. Jump to Running The Application

Running the Application

  1. Open the bootloader project bootloader/firmware/pic32wm_bz6_curiosity.X in the IDE

  2. Build and program the application using the IDE on to the Target development kit

    • RGB_LED_RED will be turned-on to indicate that bootloader code is running on the target
    • RGB_LED_RED will also turn on when the bootloader does not find a valid application; i.e. the first word of the application (stack pointer), contains 0xFFFFFFFF

  3. If the test application is being programmed, Open the Terminal application (Ex.:Tera Term) on the computer and configure the serial port settings for Target Development kit as follows:

    • Baud : 115200
    • Data : 8 Bits
    • Parity : None
    • Stop : 1 Bit
    • Flow Control : None

  4. Press the Switch SW0 on the Host development kit to trigger programming of the application binary

  5. Once the programming is complete,

    • LED0 on the Host development kit will be turned on indicating success

    • The target development kit need to be reset. Press the NMCLR switch, the boot-loader will jump to the user application

    • If the test application is programmed then RGB_LED_RED should start blinking and you should see below output on the Target development kit console

      output

  6. Press and hold the Switch USR BTN1 to trigger Bootloader from test application and you should see below output

    output

  7. Press Reset button on the Host development kit to reprogram the application binary

  8. Repeat Steps 4-5 once

    • This step is to verify that bootloader is running after triggering bootloader from test application in Step 6
