[Linuxptp-users] LinuxPTP using intel TSE MAC IP and DP83640

[Vitor W. <vit...@aq...>]

This is my first time on the Source Forge mailing list, so I apologize if i dont follow some community guidelines.



I am trying to make an implementation for PTP time synchronization using a DP83640 PHY + intel TSE MAC + LinuxPTP stack. The Hardware Time Stamps are created in the PHY and the Linux PTP stack receive this information through the TSE MAC via MII.



Checking the time stamp capabilties of my ethernet adapter using ethtol -t eth0 i get the following:

Apparently, i should be okay to use the linuxPTP software, however, when i try to run it or even use the debug tool hwstamp_ctl i get the following:

I thought i configured all the drivers correctly, as well as the device tree. It seems to be a driver related problem. Does anyone have any idea of what the problem could be?



I am using Linux Kernel Version: 5.4.94 and LinuxPTP Version: 3.1
