ls1021a-iot Ethernet Switches not WORKING!!

[shimsangwon]

Hello.

I am currently using the ls1021a-iot board. The switch can not be set after installing the Linux kernel provided by nxp on the board.

What I use is

https://www.nxp.com/support/developer-resources/reference-designs/qoriq-ls1021a-iot-gateway-referenc...

'LEDE', OpenWRT, and the Linux SDK Source ISO (REV0.1).

The Ethernet switch did not work with all three versions.

The second and third kernels build the Linux SDK Source ISO (REV 0.1) with fsl-image-rds, fsl-image-core.

The following is the contents of U-Boot and Ethernet contents set in Ethtool.

Here is what I would like to ask you.

1. eth2 is an Ethernet Switch, so how do you check the ip list connected to eth2?

2. eth2 is linked, but you can actually connect to eth2 and try to ping or connect with ip. Is there a way to set it up separately?

I have built it into a document and tried to use eth0 and eth2 with br-lan. But it was not all.

I have tried to solve the problem for a long time, but it is not done and I need help.

Thank you in advance.

Sorry for delayed response.

You said:

"/ * ETSEC3 is not set here. Is there anything that does not matter?
   I have eTSEC3 set up for other users. * /

According to board schematic, L2 switch is connected to ETSEC3, so using ETSEC3 for other purposes is not possible.

Have a great day,
Alexander
