Yeah, I'm currently working on PTP support for STM32F4 platform. The PTP daemon is mostly done, with the few missing features noted in the pull request linked above. For highest resolution, the platform should have support for timestamping arriving and leaving ethernet packets. Currently there are not yet NuttX drivers for that. But being an RTOS, it will probably achieve better than 0.1 ms accuracy even without hardware timestamping, provided that a high resolution RTC is available. My plan is to next add support for STM32F4 to use the ethernet peripheral 64-bit timestamp counter for the system time source, and to query timestamps from that through SO_TIMINGS ioctl call. -- This is an automated message from the Apache Git Service.
