DP83867IS: 100 MBPS IS WORKING BUT 1G IS NOT WORKING,PART NO USED IS DP83867ISRGZ.

Part Number: DP83867IS

HI,

THIS IS KISHORE .WE HAVE A CUSTOM BOARD (XILINX ARTIX 7 FPGA) WHICH IS INTERFACED TO TI PART NO :DP83867ISRGZ IN RGMII MODE.

STRAP CONFIGURATIONS ARE AS FOLLOWS:

GPIO_0   : MODE3

GPIO_1   : MODE2

LED_0     : MODE1

LED_1     : MODE2

LED_2     : MODE1

RX_CTRL     : MODE3

RX_D0         : MODE1

RX_D2         : MODE1.

WE HAVE CHECKED ALL THE VOLTAGES AT THE RESPECTIVE STRAPS AND IT IS WITH IN THE RANGE AS PER THE DATASHEET.

DURING  AUTONEG  1G SPEED IS DETECTED BUT IT'S NOT PINGING.

-----lwIP TCP echo server ------
TCP packets sent to port 6001 will be echoed back

Configuring default IP of 192.168.1.10
Board IP: 192.168.1.10
Netmask : 255.255.255.0
Gateway : 192.168.1.1
TCP echo server started @ port 7.

KINDLY HELP US ,THE PROJECT IS IN CRITICAL STAGE .KINDLY ARRANGE TO SEND YOUR APPLICATION ENGINEER TO OUR WORK PLACE.

    Hi naga,

    I am contacting our field sales to discuss contact with a field applications engineer.

    Looking at your configuration for RGMII delays, you have the TX delay set to 0ns. This may be OK for 100M, but probably will not work for 1000M unless your FPGA also has skew implemented.

    Please try placing LED_1 in strap mode 1. Or try changing register 0x0086 = 0x77 when in 1000M mode.

    Best Regards,
