The following steps demonstrate the boot sequence for the SD-boot mode.

  1. To verify the image, copy the required images to the SD card:

    • For standalone, copy the BOOT.BIN to the SD card.

    • For Linux images, navigate to the <plnx-proj-root>/images/linux and copy BOOT.BIN, Image, rootfs.cpio.gz.uboot, boot.scr to the SD card.

    Note

    You can either boot the VCK190/VMK180/VPK180 board using the ready-to-test images as part of the released package path, <design-package>/<vck190 or vmk180 or vpk180>/ready_to_test/qspi_images/linux/, or refer to Example Project: Creating Linux Images Using PetaLinux to build your own set of Linux images using the PetaLinux tool.

  2. Load the SD card into the VMK180/VCK190/VPK180 board in the J302 connector.

  3. Connect the Micro USB cable into the VMK180/VCK190/VPK180 Board Micro USB port (J207), and the other end into an open USB port on the host machine.

  4. Configure the board to boot in SD-Boot mode (1-ON, 2-OFF, 3-OFF, 4-OFF) by setting the SW1 switch as shown in the following figure.

  5. Connect 12V power to the VMK180/VCK190/VPK180 6-Pin Molex connector.

  6. Start a terminal session using Tera Term or Minicom depending on the host machine being used. Set the COM port and baud rate for your system, as shown in the following figure.

  7. For port settings, verify COM Port in the device manager and select the com port with interface-0.

  8. Turn on the VMK180/VCK190/VPK180 board using the power switch (SW13).

    Note

    Logs for standalone images are displayed on the terminal. For Linux images, you can log in using user: root and pw: root after the boot-up sequence on the terminal. After that, run gpiotest on the terminal. You will see logs as shown in the following figure.
