Other Parts Discussed in Thread: TMDXIDK5718, TLK105L, DP83848C
Hi,
I'm using SDK-LINUX-AM57X 06_03_00_106 on our custom board.
Our board has 3 ethernet ports .
It is similer to TMDXIDK5718. But it doesn't have 2 Gigabit (1000Mb) Ethernet Ports.
All 3 ports are 100Mb Ethernet Ports on PRU-ICSS.
The PHY device DP83848MSQ/NOPB instead of TLK105L.
Mdio found PHY devices.
davinci_mdio 4b232400.mdio: phy[1]: device 4b232400.mdio:01, driver NS DP83848C 10/100 Mbps PHY <- pruss1_emac0
davinci_mdio 4b2b2400.mdio: phy[1]: device 4b2b2400.mdio:01, driver NS DP83848C 10/100 Mbps PHY <- pruss2_emac1
davinci_mdio 4b2b2400.mdio: phy[3]: device 4b2b2400.mdio:03, driver NS DP83848C 10/100 Mbps PHY <- pruss2_emac0
pruss1_eth driver was initialized. But pruss2_eth(pruss2_emac0 and pruss2_emac1) not.
In prueth.c
"prueth_netdev_init" returned -517.
/* connect PHY */
emac->phydev = of_phy_connect(ndev, emac->phy_node,
&emac_adjust_link, 0, emac->phy_if);
if (!emac->phydev) {
dev_dbg(prueth->dev, "couldn't connect to phy %s\n",
emac->phy_node->full_name);
ret = -EPROBE_DEFER;
goto free;
}
"of_phy_connect" returned NULL.
