I'm trying to use the DP83869HM in SGMII-Copper mode but cannot get it to work.
The SGMII interface of the DP83869HM is connected to the SGMII of a KSZ9897S Microchip switch device.
The DP83869HM is also connected to an RGMII interface of a Xilinx Zynq-7000 device and to an RJ45 connector.
The circuitry works, i.e. I can get ethernet traffic through the switch, when the DP83869HM is in
RGMII-to-SGMII mode (Zynq to switch traffic) and when in RGMII-to-copper mode (Zynq to RJ45 traffic).
I now want to set the DP83869HM into SGMII-Copper mode to get switch to RJ45 traffic but when using the
following settings from SNLS614A (except autonegotiation is disabled), I don't get traffic through the switch from the RJ45
0x01DF=0X0006 (also tried 0x0046)
0x0000=0x0140
0x0010=0x5048
0x0009=0x0B00 (also tried 0x1B00 and 0x1300)
0x0c00=0x0140
I have set the SGMII interface of the switch (KSZ9897S) to non-autonegotiation, full duplex, 1Gbps and it is set in MAC-side mode.
I would appreciate any help to get the correct configuration/setup.
