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?
