Hey Z,
I'll leave the big questions to the three folks I mentioned above who are taking over, as this is my last day. We're running the board through the paces at the moment and are looking into next steps from a software, RTL and marketing perspective.
As for the hardware timestamping, we have gotten to a point where we are just debugging the driver changes in Yocto. Hoping that the team can post good news on that front soon.
All the best!
Matt
