I am working with Xilinx Zynq ultrascale+ , that is built around custom board. In this board I have 3 gems -gem0..gem2 that are connected to DP83867IS PHY. in addition, my system is working in SGMII , 100base-tx mode.
I am trying to find simple, easy to deploy bare metal test procedure for the MAC (gem) and PHY (dp83867) in external loopback mode. That is to test among other things the pcb connections of the PHY component, magnetics all the way to RJ45.
The first thing that I tried was to implement ping test with lwIP library: https://xilinx-wiki.atlassian.net/wiki/spaces/A/pages/18842366/Standalone+LWIP+library Here in the webpage you can see that SGMII is not supported in GEM and indeed it didn't work.
So I wonder if there is a test- ping or just sending data packets from gem0 through the PHY and outside, to verify the connections?
