Dear @xiaolei.qin,
Could you check below steps if it works.

Connect HMTD cable between 88Q4364 and validate the loopback

  • Make sure the FW is udpated to 7.1.8.
 cd /usr/lib/firmware/marvell_ethernet/88Q4364/
   ./flash_4364 --GetCurrentVersion mgbe0_0
   ./flash_4364 --Install mgbe0_0 Arc-7.1.8.fw.image-ARC_9KB_nvidia_Main_MSMode-GPIO_ID58_VER2031.nvm.bin

Flashing time is around 12 to 15 minutes

  • Reboot device and Test Steps to verify this REQ
    Step1> Connect both 88Q4384 port back to back on MGBE0 instance with HMTD cable.
    Step2> execute master on one Orin.

  • Use set_mode_4364 <master(1)/slave(0)> to set mode.

# set master mode on first orin
  ./set_mode_4364 mgbe0_0 1
# set slave on another Orin.
   ./set_mode_4364 mgbe0_0 0
# Assign static IP on both Orin boards.
   ifconfig mgbe0_0 192.168.1.1 up #Master Orin
   sudo ifconfig mgbe0_0
   ifconfig mgbe0_0 192.168.1.2 up #Slave Orin
   sudo ifconfig mgbe0_0
