Hello, We have been using LinuxPTP with great success on a system with a dp83640 PHY and DaVinci MAC running Linux 4.2. We now need to move to a 1 GigE based system with PHY-based timestamping, but it seems that no driver exists which supports the PHC of the PHY we're targeting.
The system we're targeting is the TI am335x Starter Kit (TMDSSK3358), which uses the Qualcomm Atheros ar8031 PHY, and the MAC in the am335x processor uses the TI CPTS for timestamping. I found a previous response from Richard on the linuxptp-devel mailing list (URL: https://sourceforge.net/p/linuxptp/mailman/message/31706496/) which states "Right now, the dp83640 is only PHY driver in the kernel with time stamping and PHC supported", but since that was written on 2013-12-02 I am hopeful that there may be more options by now. However, the mainline ar8031 PHY driver has no PHC support, and I see no other PHY-based timestamping solutions listed in the Driver Support Matrix in LinuxPTP's current readme file. Is there any chance that a driver for the ar8031 with timestamping and PHC support exists outside of mainline Linux so that we could still potentially use this platform? Even an in-development driver could be an option for us. If not, is this group aware of any alternative 1 GigE PHYs with PHC Linux driver support of some sort? Any help or suggestions would be greatly appreciated. Dave
