Dear all,
I´m trying to config the KSZ9563 switch in the device tree of my verdin am62 on a custom carrier board. However, my device tree setup doesn´t seem to work has supposed.

&cpsw_port2 {

The carrier board hardware, as shown below, has the SOM as the MAC and the switch Port 3 has the PHY:
After flashing the am62 verdin the the boot output is the following:

For what I can see PHY can´t connect am65_cpsw_nuss_port ethernet@8000000port@2: phy_connect() failed and after boot it does not appear as an ethernet device after run ifconfig -a:

Even after forcing the device to be up, which returns SIOCSIFFLAGS: No such device.
I hope you could give me some insights on the device tree setup so that the some recognizes the switch and can connect phy.
If any other info is need, ask me.
Thank you in advance!

Carla
