Hello, I have a custom board with ls1020a processor connected with ksz9031rnx phy. In both modes 1000 base, 100 base, I have to repeated several times unplugging/plugging of cable to link up the interface. What can be a reason?
Thanks
Hello Serge Frolov,
KSZ9031RNX PHY supports RGMII, please make sure LS1021a Ethernet interface is configured as RGMII.
KSZ9031RNX PHY driver drivers/net/phy/micrel_ksz90x1.c has already been integrated in u-boot, please check whether you have already configured CONFIG_PHY_MICREL_KSZ90X1 in u-boot.
Please follow the procedure in function "ksz90xx_startup" in drivers/net/phy/micrel_ksz90x1.c to check PHY link status.
Thanks,
Yiping
Thanks, Yiping!
In 100 base mode phy works good, but in 1000 base mode link faults. In ksz9031errata said, that it may be, if 125 clk_out from phy is connected to mac core. Later I checked it.
Thanks!
