Dear All,
Now I use VSC8201PHY on MPC8347 with uboot-1.1.3,I think VSC8201 PHY is similar to CIS8201PHY,so I add struct phy_info_vsc8201 based on struct phy_info_cis8201 in tsec.c and related registers in tsec.h, but during bootup I meet below problem in tsec.c when it goes to read phy_id in function read_phy_reg(), the phy_id is always ffffffff, the log file is as follow:
Net: TSEC initialize begin... In Read reg func PHY ID is:0 Register number MIIMADD is 2 PHY Reg after read PHYIR1 is:ffff PHY Reg High 16 bit is:ffff0000 Begin Read phy reg! In Read reg func PHY ID is:0 Register number MIIMADD is 3 PHY Reg after read PHYIR2 is:ffff Tsec: read from reg is ffffffff Freescale TSEC0: PHY id ffffffff is not supported! Freescale TSEC0: No PHY found TSEC initialize begin... In Read reg func PHY ID is:1 Register number MIIMADD is 102 PHY Reg after read PHYIR1 is:ffff PHY Reg High 16 bit is:ffff0000 Begin Read phy reg! In Read reg func PHY ID is:1 Register number MIIMADD is 103 PHY Reg after read PHYIR2 is:ffff Tsec: read from reg is ffffffff Freescale TSEC1: PHY id ffffffff is not supported! Freescale TSEC1: No PHY found Freescale TSEC0, Freescale TSEC1
Thanks in advance.
