LX2160ARDB Ethernet port mapping

In the U-Boot log, the names of the Ethernet interfaces are printed in the format <name>@<interface type>, for example, DPMAC3@xgmii. DPMAC is a DPAA2 object that identifies the physical interface. 

 

Interface name is not fixed in LX2160ARDB, depending upon which interface is active, name will be assigned  in TinyDistro as well as in Ubuntu distribution.
Interface names can be checked using ls-listni command.

root@TinyDistro:~# ls-listni
dprc.1/dpni.1 (interface: eth0, end point: dpmac.2)
dprc.1/dpni.0 (interface: eth1, end point: dpmac.17)

 

For details regarding creation of a DPAA2 network interface (DPNI) in Linux, see "LSDK Quick Start Guide for LX2160ARDB -> Bringing up DPAA2 network interfaces" in Layerscape Software Development Kit User Guide.

 

The table below shows the mapping of Ethernet port names appearing on the chassis front panel with the port names in U-Boot and Linux for LX2160ARDB.
