Other Parts Discussed in Thread: MIO,
Hello TI Support,
I'm having issues with the Ethernet on a custom board with a ZynqMP and the Ti83867 PHY running in SGMII mode.
We have a custom board designed with Xilinx Zynq Ultrascale+ FPGA. We connect to port 0 as GEMO(EMIO) <-->SGMII over LVDS <---> External PHY use TI DP83867.
When boot up Linux, I cannot dhcp, and I cannot get any activity on wireshark.
I can set IP address and ping itself, but cannot ping outside.
My Linux log:
