Subject: Re: Micrel KSZ8031 - phy link missing
Dear Bruno,
many thanks,
i still have the issue after patching kernel 3.17.
static int ksz8021_config_init(struct phy_device *phydev)
{
const u16 val = KSZPHY_OMSO_B_CAST_OFF | KSZPHY_OMSO_RMII_OVERRIDE;
int rc;
rc = kszphy_setup_led(phydev, 0x1f, 4);
if (rc)
dev_err(&phydev->dev, "failed to set led mode\n");
/*
* signalled no-link to linux-net community, followed
* see [PATCH] phy/micrel: KSZ8031RNL RMII clock
reconfiguration bug
*/
rc = ksz_config_flags(phydev);
if (rc < 0)
return rc;
rc = phy_write(phydev, MII_KSZPHY_OMSO, val);
return rc < 0 ? rc : 0;
}
I am using RMII in my custom board, don't know if it makes any difference.
