Bootloader Installation: HMI3

Installing the KOS bootloader installs the node manager, the necessary software to recognize the board as a KOS device. KOS Studio recognizes KOS Devices and can interact with them as needed.

Node discovery lists all the possible devices running KOS in your network and all devices connected via KOS Studio within your organization.

Prerequisites

Software:

  • Ensure your Mac or Windows machine has the Raspberry Pi Imager installed. If needed, you can install it from here.

Hardware:

  • A Windows or Mac machine with a USB Standard-A port (or the with supported USB hub or adapter)
  • A HMI3 board with power and screen connected.
  • A USB type-A flash drive.

Step 1: Download the bootloader.

  • Download the HMI3 bootloader.
    • In Mac OS, the file is automatically unarchived, and the *.img file will be in the download location.
    • In Windows, the user must unarchive the downloaded file and use *. img for flashing.

Step 2: Prepare the USB thumb drive

  • Connect the USB flash drive to the Mac / PC.
  • Start the RPi Imager installed on the machine.
  • Locate and select the ‘.img’ and select the inserted flash drive.
  • Follow the instructions for RPi Imager to flash the image to the flash drive.

Step 3: Flash the HMI3 board

  • Insert the USB-A thumb drive into one of the USB-A ports of the HMI3 board.

  • Switch on the board.
  • The bootloader will install automatically and wait for the installation complete message on the screen.
Installation complete. Remove the Installation media and reboot.

Step 4: Verification

  • Now remove the thumb drive and reboot the HMI3 board.
  • Connect the HMI 3 board with ethernet.
  • Power up the board and wait for a few seconds to boot up.
  • The Node Manager screen with the IP is displayed.
  • You can use this IP in KOS Studio to interact with the device such as installing your device images.
