Hi, I'm trying to get ptp4l to sync with my GM using G.8275.2 profile using DSA with Microchip PTP support and lan1 acting as an individual NIC. I had this profile working before on a development board that had a dumb phy but now using a board that has a Microchip KSZ9567 which is a 7 port switch with port 7 connected to imx8mm via RGMII.
The weird thing is if I use plain 1588 profile (PTP), it will work both direct connected and thru switch so might be a E2E issue. I'm using linuxptp 2.0 with Yocto Dunfell build. Using fslc-linux 5.4.114 kernel. My GM is Trimble Thunderbolt GM200. If my board is directly connected to the GM using G.8275.2, it will sync and give very small GM offset numbers. But when I go through a dumb switch I get crazy delay numbers and ptp4l will never sync. If I try this exact same setup using regular 1588 profile instead of G.8275.2 profile, my GM offsets usually run +/- 300 range when connected thru switch. I hope I just have a configuration setting wrong that's causing this issue but I'm just not seeing it. I do have tcpdump on the target so will try to get some captures to see if I can determine any differences in the messaging between the two use cases and post them. But for now I'll just show the console output for the two cases below ... direct connected to GM vs going thru switch.
