Не вводите людей в заблуждение.
88E1111 прекрасно работает как с прямым, так и с кросс кабелем.
Вот пример правильной инициализации 88E1111 для RGMII:
case PHY_ID_88E1111:
{
MDIO_PHY_ADDR = PHY_ADDR_88E1111 ;
uint16_t data ;
data = rd_mdio (0) ;
data |= ((1<<12) | (1<<8)) ;
data &= ~((1<<14) | (1<<11) | (1<<10)) ;
wr_mdio (0, data) ;
data = rd_mdio (4) ;
data |= ((1<<8) | (1<<6)) ;
data &= ~((1<<10) | (1<<7) | (1<<5)) ;
wr_mdio (4, data) ;
data = rd_mdio (9) ;
data |= ((1<<9)) ;
data &= ~((1<<15) | (1<<14) | (1<<13) | (1<<8)) ;
wr_mdio (9, data) ;
data = rd_mdio (16) ;
data |= ((1<<15) | (1<<14) | (1<<13) | (1<<12) | (1<<6) | (1<<5)) ;
data &= ~((1<<4)) ;
wr_mdio (16, data) ;
data = rd_mdio (27) ;
data &= ~((1<<3) | (1<<2) | (1<<1) | (1<<0)) ;
data |= ((1<<3) | (0<<2) | (1<<1) | (1<<0)) ;
wr_mdio (27, data) ;
data = rd_mdio (20) ;
data &= ~((1<<7) | (1<<1)) ;
data |= ((1<<7) | (1<<1)) ;
wr_mdio (20, data) ;
data = rd_mdio (29) ;
data &= ~0x001F ;
data |= 16 ;
wr_mdio (29, data) ;
data = rd_mdio (30) ;
data |= ((1<<0)) ;
wr_mdio (30, data) ;
data = rd_mdio (0) ;
data |= ((1<<15)) ;
wr_mdio (0, data) ;
__delay_cycles (const20ms) ;
poll_speed = false ;
mac_config = (LINK_AUTO<<ETH1000_SPEEDSEL0) |
(0<<ETH1000_MACFLTDISABLE) |
(1<<ETH1000_TXGENERATEIPV4) |
