Flash Images

Once you have generated the system image using the Qualcomm Robotics Download Manager:

  1. Turn off the Qualcomm Robotics RB5 development kit.

  2. Press the F_DL button and connect the power source

  3. Keeping F_DL button pressed, connect the USB Type-C to Qualcomm Robotics RB5 development kit and the other end to the Ubuntu machine.

  4. Once this is correctly done, the flash will begin automatically.

    Note: The images will not flash if the device is not in download mode.

    After the flashing is successful, adb should come up. If not, please power cycle the development kit. Since the system images are flashed, there is no need to press the F_DL key to force the device to enter the Emergency Download Mode. $ adb devices

  5. Once the flashing process is complete, adb should be available. Proceed to Qualcomm's SDKs (Qualcomm FastCV, Hexagon DSP SDK, SNPE) using SDKManager. These SDKs are available on the Qualcomm Developer Network. Next, you can proceed to Network Setup.
