Reboot ROCK 3C.
root@rock-3c:~# reboot
Step3: Load kernel module
root@rock-3c:~# modprobe g_ether root@rock-3c:~# dmesg -c [ 108.290807] using random self ethernet address [ 108.290820] using random host ethernet address [ 108.292182] usb0: HOST MAC 9a:ec:b8:df:56:60 [ 108.292322] usb0: MAC 52:4c:1e:5e:dd:aa [ 108.292382] using random self ethernet address [ 108.292391] using random host ethernet address [ 108.292504] g_ether gadget: Ethernet Gadget, version: Memorial Day 2008 [ 108.292513] g_ether gadget: g_ether ready [ 108.403372] dwc3 fcc00000.dwc3: device reset [ 108.530261] dwc3 fcc00000.dwc3: device reset [ 108.685170] g_ether gadget: high-speed config #2: RNDIS
Step 4: Bring up the usb0 device
root@rock-3c:~# ifconfig usb0 up
Now you should have usb0 on ROCK 3C enabled.
Step 5: Check usb0 network card on ROCK 5B.
On ROCK 5B Debian11, the dmesg gives something like below:
root@rock-5b:~# dmesg -c [ 334.470377] usb 2-1: new high-speed USB device number 2 using ehci-platform [ 334.620061] usb 2-1: New USB device found, idVendor=0525, idProduct=a4a2, bcdDevice= 4.19 [ 334.620088] usb 2-1: New USB device strings: Mfr=1, Product=2, SerialNumber=0 [ 334.620107] usb 2-1: Product: RNDIS/Ethernet Gadget [ 334.620125] usb 2-1: Manufacturer: Linux 4.19.193-1-rk356x with dwc3-gadget [ 334.634014] rndis_host 2-1:2.0 usb0: register 'rndis_host' at usb-fc880000.usb-1, RNDIS device, c2:e5:aa:9d:8f:e0
usb0 is the "USB network card" for ROCK 3C and ROCK 5B
Step 6: Setup USB Network
On ROCK 3C

root@rock-5b:~# HOST_IP=10.0.1.2 root@rock-5b:~# ifconfig usb0 $HOST_IP netmask 255.255.255.0
Step 7: Test network via ping
on ROCK 5B
root@rock-5b:~# ifconfig usb0 usb0: flags=4163<UP,BROADCAST,RUNNING,MULTICAST> mtu 1500 inet 10.0.1.2 netmask 255.255.255.0 broadcast 10.0.1.255 ether c2:e5:aa:9d:8f:e0 txqueuelen 1000 (Ethernet) RX packets 37 bytes 2464 (2.4 KiB) RX errors 0 dropped 0 overruns 0 frame 0 TX packets 145 bytes 28585 (27.9 KiB) TX errors 58 dropped 0 overruns 0 carrier 0 collisions 0
On ROCK 3C, ping 'ROCK 5B'
