Has anyone looked into Micro-ROS and PTP? RA6M3 and some of the STM32 Nucleo-144 boards list it as a feature in the datasheets.
I briefly experimented with a PTP clock. Windows was a no-go at the time and ptp4l compared well against a IRIG-B PCIe timing card. We currently use IRIG-B but are looking to transition to PTP in the near future.
