ZYNQ使用88E1510 PHY芯片的驱动程序
2024-08-30 17:01:14
SDK V2014.4
PHY 88E1510
PL端以太网，自协商
standalone应用程序
PL端设计，略。
根据PL端生成的hdf，新建项目，采用官方lwip echo server例程。发现运行结果为
-----lwIP TCP echo server ------
TCP packets sent to port 6001 will be echoed back
auto-negotiated link speed: 69073
很明显不对。
1、调试发现运行到 xaxiemacif_physpeed.c文件中的get_IEEE_phy_speed()函数时，phy_model = 464 = 0x1D0，不属于例程自带的以下两个型号：
if (phy_identifier == MARVEL_PHY_IDENTIFIER) {
if (phy_model == MARVEL_PHY_88E1116R_MODEL) {
return get_phy_speed_88E1116R(xaxiemacp, phy_addr);
} else if (phy_model == MARVEL_PHY_88E1111_MODEL) {
return get_phy_speed_88E1111(xaxiemacp, phy_addr);
}
}
2、所以加入该型号的驱动函数：
#define MARVEL_PHY_88E1510_MODEL 0x1D0
unsigned get_phy_speed_88E1510(XAxiEthernet *xaxiemacp, u32 phy_addr)
{
u16 temp;
u16 phy_identifier;
u16 phy_model;
u16 control;
u16 status;
u16 partner_capabilities;
xil_printf("in get_phy_speed_88E1510.\r\n");//FOR DEBUG
/* Get the PHY Identifier and Model number */
XAxiEthernet_PhyRead(xaxiemacp, phy_addr, 2, &phy_identifier);
XAxiEthernet_PhyRead(xaxiemacp, phy_addr, 3, &phy_model);
phy_model = phy_model & PHY_MODEL_NUM_MASK;
XAxiEthernet_PhyWrite(xaxiemacp,phy_addr, IEEE_PAGE_ADDRESS_REGISTER, 2);
XAxiEthernet_PhyRead(xaxiemacp, phy_addr, IEEE_CONTROL_REG_MAC, &control);
//control |= IEEE_RGMII_TXRX_CLOCK_DELAYED_MASK;
control &= ~(0x10);
XAxiEthernet_PhyWrite(xaxiemacp, phy_addr, IEEE_CONTROL_REG_MAC, control);
XAxiEthernet_PhyWrite(xaxiemacp, phy_addr, IEEE_PAGE_ADDRESS_REGISTER, 0);
XAxiEthernet_PhyRead(xaxiemacp, phy_addr, IEEE_AUTONEGO_ADVERTISE_REG, &control);
control |= IEEE_ASYMMETRIC_PAUSE_MASK;
control |= IEEE_PAUSE_MASK;
control |= ADVERTISE_100;
control |= ADVERTISE_10;
XAxiEthernet_PhyWrite(xaxiemacp, phy_addr, IEEE_AUTONEGO_ADVERTISE_REG, control);
XAxiEthernet_PhyRead(xaxiemacp, phy_addr, IEEE_1000_ADVERTISE_REG_OFFSET, &control);
control |= ADVERTISE_1000;
XAxiEthernet_PhyWrite(xaxiemacp, phy_addr, IEEE_1000_ADVERTISE_REG_OFFSET, control);
XAxiEthernet_PhyWrite(xaxiemacp, phy_addr, IEEE_PAGE_ADDRESS_REGISTER, 0);
XAxiEthernet_PhyRead(xaxiemacp, phy_addr, IEEE_COPPER_SPECIFIC_CONTROL_REG, &control);
control |= (7 << 12); /* max number of gigabit attempts */
control |= (1 << 11); /* enable downshift */
XAxiEthernet_PhyWrite(xaxiemacp, phy_addr, IEEE_COPPER_SPECIFIC_CONTROL_REG, control);
XAxiEthernet_PhyRead(xaxiemacp, phy_addr, IEEE_CONTROL_REG_OFFSET, &control);
control |= IEEE_CTRL_AUTONEGOTIATE_ENABLE;
control |= IEEE_STAT_AUTONEGOTIATE_RESTART;
XAxiEthernet_PhyWrite(xaxiemacp, phy_addr, IEEE_CONTROL_REG_OFFSET, control);
XAxiEthernet_PhyRead(xaxiemacp, phy_addr, IEEE_CONTROL_REG_OFFSET, &control);
control |= IEEE_CTRL_RESET_MASK;
XAxiEthernet_PhyWrite(xaxiemacp, phy_addr, IEEE_CONTROL_REG_OFFSET, control);
while (1) {
XAxiEthernet_PhyRead(xaxiemacp, phy_addr, IEEE_CONTROL_REG_OFFSET, &control);
if (control & IEEE_CTRL_RESET_MASK)
continue;
else
break;
}
xil_printf("Waiting for PHY to complete autonegotiation.\r\n");
XAxiEthernet_PhyRead(xaxiemacp, phy_addr, IEEE_STATUS_REG_OFFSET, &status);
while ( !(status & IEEE_STAT_AUTONEGOTIATE_COMPLETE) )
{
sleep(1);
XAxiEthernet_PhyRead(xaxiemacp, phy_addr, IEEE_COPPER_SPECIFIC_STATUS_REG_2, &temp);
if (temp & IEEE_AUTONEG_ERROR_MASK)
{
xil_printf("Auto negotiation error \r\n");
}
XAxiEthernet_PhyRead(xaxiemacp, phy_addr, IEEE_STATUS_REG_OFFSET, &status);
}
xil_printf("autonegotiation complete \r\n");
XAxiEthernet_PhyRead(xaxiemacp, phy_addr, IEEE_SPECIFIC_STATUS_REG, &partner_capabilities);
if ( ((partner_capabilities >> 14) & 3) == 2)/* 1000Mbps */
return 1000;
else if ( ((partner_capabilities >> 14) & 3) == 1)/* 100Mbps */
return 100;
else /* 10Mbps */
return 10;
}
3、然后将 get_IEEE_phy_speed()函数改为：
if (phy_identifier == MARVEL_PHY_IDENTIFIER) {
if (phy_model == MARVEL_PHY_88E1116R_MODEL) {
return get_phy_speed_88E1116R(xaxiemacp, phy_addr);
} else if (phy_model == MARVEL_PHY_88E1111_MODEL) {
return get_phy_speed_88E1111(xaxiemacp, phy_addr);
}
//新加
else if (phy_model == MARVEL_PHY_88E1510_MODEL) {
return get_phy_speed_88E1510(xaxiemacp, phy_addr);
}
}
4、编译运行结果正确：
-----lwIP TCP echo server ------
TCP packets sent to port 7 will be echoed back
in get_phy_speed_88E1510.
Waiting for PHY to complete autonegotiation.
autonegotiation complete
auto-negotiated link speed: 1000
Board IP: 192.168.1.10
Netmask : 255.255.255.0
Gateway : 192.168.1.1
TCP echo server started @ port 7
5、官方例程是回显网口数据，即在网口输入什么就输出什么，如果想在串口也输出，可以改下recv_callback()函数：
if (tcp_sndbuf(tpcb) > p->len) {
err = tcp_write(tpcb, p->payload, p->len, 1);
xil_printf("%s\n\r",(char*)( p->payload)); //加上这句话即可在串口也回显网口数据
} else
xil_printf("no space in tcp_sndbuf\n\r");
