boards: phytec-som-am335x: ethernet broken after reset

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



Hi Teresa,

With the current code for the phytec-som-am335x, the ethernet works only
after the first powerup. If you soft reset the module the network won't
work anymore.

...
cpsw 4a100000.ethernet: detected phy mask 0x6
mdio_bus: miibus0: probed
cpsw 4a100000.ethernet: Failed to setup slave 0: I/O error
...

That happens in the second boot. The phy is probably in a wrong state and
won't communicate over MDIO.

Do you have any ideas?

Thanks,
Michael
