ls12028ardb l2switch issue

pjw — Fri, 13 Nov 2020 01:46:32 GMT

Hi, I'm testing custom boards with ls1028ardb.

What is currently being tested is the l2switch part.
Part 4.1.12.3.2 of LS1028A_BSPv02_Rev0.
Now, on the custom board,
eno0 / eno2 / switch / swp0 / swp1 / swp2 is available.

The test method is as follows.

1. Complete the ENETC interface sh file as manual and execute the file.
2. ip addr add 192.168.2.1/24 dev switch
3. Connect swp0 and laptop by wlan (Note that laptop ip is designated as 192.168.2.2)

The ---> problem is this part.
Ping 192.168.2.1 on the laptop to activate.
However, ping 192.168.2.2.2 on the board does not work.

Then, after designating the ip of swp0 as 192.168.2.3, ping 192.168.2.3 on the laptop gives the signal.
However, ping 192.168.2.2.2 shall not be tested on the board.

Is this how it works?
As far as I understand, in L2Switch mode, the board acts as a hub, so I understood that the hosts are connected.
Therefore, I understood that communication should be possible if each host pc is connected to swp0/swp1/swp2 and the ip is set to 192.168.2.xxx.

If not, is another way necessary?
