DP83867IR: configure 1000M communication failure.

user503335153

Part Number: DP83867IR

External power VDD1V8 suspension,other " strap " are "mode1",Configured to 100Mbps, successful communication, but 1000Mbps failure . "testmode" and "lockmode" are ok in 1000Mbps configure. 1000Mbps register configuration is as follows:

adr0x001f=0x8000; //reset register

adr0x0000=0x0140; //1000Mbps,full duplex

adr0x0010=0x5008; // close SGMII

adr0x0009=0x1b00/0x0300/0x1300; // configure PHY full duplex

adr0x0032=0x00d3/0x00d0; // enable RGMII

adr0x0086=0x0000; // RGMII Sending and receiving clock delay 2.5ns

adr0x31=0x0030; // configure rx_ ctl in strap Non mode 1 and mode 2

After configuration is completed, read the PHY(0x0011) state is 0x2802 Why ?and can't recive any data. Is there any problem with configuration?

Hi,

Register 0x0000 : 0x0140. This indicates Auto-negotiation is disabled. Please check all your HW straps are configured properly as provided in datasheet.

which are HW straps registers?I configured the register that is showed in top post,and others is default. My cpu is FPGA, Which registers are what I have to configure, except those configured below?
adr0x0000=0x0140; //1000Mbps,full duplex
adr0x0010=0x5008; // close SGMII
adr0x0009=0x1b00/0x0300/0x1300; // configure PHY full duplex
adr0x0032=0x00d3/0x00d0; // enable RGMII
adr0x0086=0x0000; // RGMII Sending and receiving clock delay 2.5ns
adr0x31=0x0030; // configure rx_ ctl in strap Non mode 1 and mode 2

Hi,

Following two register provides options reading of the strap values.

1. 0x006E
2. 0x006F
