Switch ports swp0-3 not working on LS1028ARDB w/LS SDK 1909

[trp]

Hello,

The title says it all ..

We have managed to get eno0 to work; however the switch ports are all DOWN. We have followed all the instructions in the LS SDK 1909 manual.

We did not have the same problem with BSP 0.3.

How do we fix this?

Regards,

Tom Roar
