Hi all,
I'm working to port owrt/lede on the dwr-921 (mt7620n based).
Currently I'm able to complete the boot but the wan port (port 4) doesn't
work.
All the other lan port (port 0-3) are working properly.
Yesterday with blogic we though the problem was related to the assignment of
the port-4 to the embedded switch using the
mediatek,port4 = "ephy";
property in the dts, but also this doesn't work.
I check in the datasheet and I see that this feature is valid only in the
mt7620a.
According to the DS the mt7620n have only one switch configuration with 5 FE
port:
MT7620N MT7620A
Switch 5p FE SW 5p FE SW + RGMII(1)
4p FE SW + RGMII(2)
When I try, using the oem system, to switch from the 3g wan to the eth wan I
get the following messages on the console:

And the wan port work as expected.
Therefore, in some way, some sort of configuration is required.
Any ideas?
