Hello,
1>My board is xilinx vcu118 with ti83867 . it works ta SGMII mode. There is a GMII-SGMII bridge inside xilinx fpga
2>it can finish auto-negotiation with partner for 10Mbps ,or 100Mbps,or 1000Mbps speed. the bit[1 ]of 0x1 register shows link established.
3>The GMII rx interface of mac controller is not any response (e.g: no SFD detected)after i send ping packet from u-boot under 10Mbps or 100Mbps mode.
4>Under 1000Mbps mode ,the GMII rx interface of mac controller can ack the ping packet.however,the data reports CRC error.
there are many 0xfefefefe byte inside gmii rxdata[7:0]
how to debug?
P.s
1>Does Ti has a dp83867 software driver for sgmii mode?
2>does the bit[6] of 0x0 register need to be configed 0 with auto-negotiation enable if 10Mbps or 100Mbps is seletced?
