转发: powerpc 405ex emac1 problem connect to single Giga phy

[zhong wang]

Hello all： 
  We use the AMCC PowerPC 405ex through emac1 way RGMII with realtek RTL8211 Giga phy linked to, At present the PHY Address is: 00110 
add delay  2ns for RGMII 
CONFIG[8:5]:AUTO_Negotiation 
1111=NWay,advertise ，all capabilities,prefer Slave 
mode;1=RGMII mode 
Clk on the hardware no problem, Mdio, mdc even on, but at Llinux / driver / net / ibm-newemac / core.c discovered phy address, phy ID at  .Config file has joined 
     NETDEVICE = Y 
     PHYLIB=Y 
     REALTEK-PHY=Y 
   But will be compiled under the best Uimage to board, the feeling of the PHY the driver has not been mounted use. The following is a kernel information :

PPC 4xx OCP EMAC driver, version 3.54 
MAL v2 /plb/mcmal, 2 TX channels, 2 RX channels 
RGMII /plb/opb/emac-rgmii at ef600b00 initialized with MDIO support 
/plb/opb/emac-rgmii at ef600b00: input 0 in RGMII mode 
eth0: EMAC-0 /plb/opb/ethernet at ef600900, MAC 00:47:41:52:52:59 
/plb/opb/emac-rgmii at ef600b00: input 1 in RGMII mode 
/plb/opb/ethernet at ef600a00: find TRL 821X Giga PHY（0x4） 
  
  But also in Llinux / driver / net / ibm-newemac / phy.c also add the operation of RTL8211bg as follows: 
#define RTL821x_PHYSR            0x11 
#define RTL821x_PHYSR_DUPLEX    0x2000 
#define RTL821x_PHYSR_SPEED       0xc000 
#define RTL821x_INER        0x12 
#define RTL821x_INER_INIT      0x6400 
#define RTL821x_INSR        0x13 
static int rtl821x_init(struct mii_phy *phy) 
{ 
       phy_write(phy, RTL821x_INER, 0x6400); //enable interrupt 
              return  0; 
} 
  
static struct mii_phy_ops rtl821x_phy_ops = { 
       .init         = rtl821x_init, 
       .setup_aneg    = genmii_setup_aneg, 
       .setup_forced  = genmii_setup_forced, 
       .poll_link = genmii_poll_link, 
       .read_link       = genmii_read_link 
}; 
  
static struct mii_phy_def rtl821x_phy_def = { 
       .phy_id           = 0x001cc912,  // for rtl8211 single phy 
   // .phy_id         = 0x001cc960,   for 8366sr inside phy 4 
       .phy_id_mask = 0x001fffff, 
       .name             = "RTL 821X Giga Phy", 
       .features  = PHY_GBIT_FEATURES, 
       //.flags           = PHY_HAS_INTERRUPT, 
       .ops        = &rtl821x_phy_ops 
  
  But will be compiled under the best Uimage to board, the feeling of the PHY the driver has not been mounted use. The following is a kernel information 
     After IP with a good PC PING board, Return Request Time Out! Troublesome players you look at what questions are
