When flashing the Ubuntu system on the RDK Ultra development kit, you need to use the D-Robotics hbupdate flashing tool. The tool is available for both Windows and Linux versions, named hbupdate_win64 and hbupdate_linux, respectively. The tool can be downloaded from the following link: hbupdate.

Tool Usage Notes:​

  • Unzip the tool's archive, ensuring the extraction path does not contain any spaces, Chinese characters, or special symbols.
  • The tool communicates with the RDK Ultra via Ethernet. To ensure fast flashing, make sure the PC has a gigabit Ethernet port and is directly connected to the development kit.
  • Set the PC's network configuration to static IP mode, as follows:
    • IP: 192.168.1.195
    • Netmask: 255.255.255.0
    • Gateway: 192.168.1.1

Flashing Procedure​

  1. Connect the RDK Ultra to your PC using an Ethernet cable and ensure that the network is reachable by pinging the device.

  2. Short the FC_REC and GND pins of the Functional Control Interface (Interface 10).

  3. Run the hbupdate main program, open the flashing tool, and select the development board model as RDK_ULTRA (this is a required option).
