Connect JH-7110 DevKit to Network

This section provides steps to connect JH-7110 DevKit to network and enter U-Boot terminal.

  1. Connect the jumper wires between the USB-to-Serial converter and the UART0 Debug pins of JH-7110 DevKit debug header. The following figure is an example:

    Figure 1. Connecting to the UART0 Debug Pins of JH-7110 DevKit
    Tip: You can also use the USB-to-Serial converter of Type-C port to connect Type-C debug port directly.
  2. Configure the serial port baud rate settings to 115200 bps.
  3. Connect JH-7110 DevKit to the network cable and power cord.
  4. Turn on JH-7110 DevKit and you will see the start-up information as follows:
