Hi,
I have just received my Mesa 7i96s today from Mr. Andrew Beck of BECK CNC.
I left W4 and W5 at their default setting ( I can't see jumpers

) And I have followed the instructions given in this thread, and I am able to ping it.
This is what I have done:
With the Ethernet cable connected between Mesa 7i96s and Raspberry Pi4
[
behai@picnc:~ $ ip link show
1: lo: <LOOPBACK,UP,LOWER_UP> mtu 65536 qdisc noqueue state UNKNOWN mode DEFAULT group default qlen 1000
link/loopback 00:00:00:00:00:00 brd 00:00:00:00:00:00
2: eth0: <BROADCAST,MULTICAST,UP,LOWER_UP> mtu 1500 qdisc mq state UP mode DEFAULT group default qlen 1000
link/ether d8:3a:dd:25:8c:37 brd ff:ff:ff:ff:ff:ff
3: wlan0: <BROADCAST,MULTICAST,UP,LOWER_UP> mtu 1500 qdisc pfifo_fast state UP mode DORMANT group default qlen 1000
link/ether d8:3a:dd:25:8c:38 brd ff:ff:ff:ff:ff:ff
]
I notice that
eth0 shows
<BROADCAST,MULTICAST,UP,LOWER_UP>
With the Ethernet cable disconnected:

behai@picnc:~ $ ip link show
1: lo: <LOOPBACK,UP,LOWER_UP> mtu 65536 qdisc noqueue state UNKNOWN mode DEFAULT group default qlen 1000
link/loopback 00:00:00:00:00:00 brd 00:00:00:00:00:00
2: eth0: <NO-CARRIER,BROADCAST,MULTICAST,UP> mtu 1500 qdisc mq state DOWN mode DEFAULT group default qlen 1000
link/ether d8:3a:dd:25:8c:37 brd ff:ff:ff:ff:ff:ff
3: wlan0: <BROADCAST,MULTICAST,UP,LOWER_UP> mtu 1500 qdisc pfifo_fast state UP mode DORMANT group default qlen 1000
link/ether d8:3a:dd:25:8c:38 brd ff:ff:ff:ff:ff:ff
]
I notice that
eth0 shows
<NO-CARRIER,BROADCAST,MULTICAST,UP>
So I guess my hardwired ethernet is eth0.
Then I log into my home router to verify that
192.168.1/24 is not in used as per the official manual instruction.
I then added the following lines into
/etc/network/interfaces:
[
auto eth0
iface eth0 inet static
address 192.168.1.121
hardware-irq-coalesce-rx-usecs 0
]
Then I ran
sudo ifdown -a followed by
sudo ifup -a, both ran successfully. I.e. they produced no output.
Then finally:
ping 192.168.1.121
The response is continuous until I pressed Control + C to interrupt.
I HAVE A QUESTION, PLEASE:
While the pinging was running, I disconnected the Ethernet cable, I expect the response to stop or at least to halt, but it did not. It continues to produce pinging notifications.
Is this normal, please?
Thank you and best regards,
...behai.
