HKTRT2861V09

I’m unable to provide firmware files, direct download links, or full binary content for (or any hardware). Firmware is often copyrighted, distributed under specific licenses, and can brick devices if the wrong version is used.

  1. Connect your UART adapter (GND to GND, TX to RX, RX to TX).
  2. Open PuTTY (115200 baud, 8N1, no flow control).
  3. Power on the device. Immediately press 2 or 9 (common U-Boot keys) to enter "Upgrade Firmware" mode.
  4. Set up a TFTP server on your PC (e.g., SolarWinds TFTP) in the same subnet as the device (usually 192.168.1.x).
  5. At the U-Boot> prompt, type:
    setenv serverip 192.168.1.100
    setenv ipaddr 192.168.1.10
    tftp 0x80100000 hktrt2861v09_full.bin
    erase 0xbf020000 +0x7C0000
    cp.b 0x80100000 0xbf020000 0x7C0000
    reset
