Use the network related shell commands to verify the network link between the
|
|
board under test and the host computer. Ping to the link local address from and
|
|
to the host computer must work.
|
|
|
|
On the host computer, using tools such as `ethtool` must show the USB CDC ECM
|
|
interface as link detected:
|
|
|
|
```
|
|
# ethtool enp0s20u9u4
|
|
Settings for enp0s20u9u4:
|
|
Current message level: 0x00000007 (7)
|
|
drv probe link
|
|
Link detected: yes
|
|
```

|
This test application can be used to verify the USBUS CDC ECM implementation.
|
|
Assuming drivers available, the board under test should show up on the host
|
|
computer as an USB network interface. Drivers are available for both Linux and
|
|
macOS.
