Hello there.
I'm trying to configure switch on RB433GL board.
I've tried a lot of combinations, but nothing works fine.
I cant figure out what I'm doing wrong...
Any idea?
How to check what is connected to which pad without schematics?
mdio scan founds:
- two 004dd033 ( AR8216/AR8236/AR83160) on phy-id 1 and 4
- switch on phy-id 0
My code looks like this:
#define RB433GL_SWITCH_PHYMASK BIT(0)
#define RB433GL_LAN_PHYMASK BIT(1)
#define RB433GL_WAN_PHYMASK BIT(4)
#define RB433GL_MDIO_PHYMASK (RB433GL_SWITCH_PHYMASK |
RB433GL_LAN_PHYMASK | RB433GL_WAN_PHYMASK)

eth0 still works fine
eth1 can detect link change on second port,
but all the data are lost somewhere deep in the qualcomm side of the wall

in all cases i can't connect to switch with swconfig

and some more configurations to be guessed:
