hello tagoshi,
they’re correct. it’s bit-4 for FS flag and bit-5 for FE flag.
so, FS with 0x10 and FE with 0x20 it means frame-start and frame-end were all received.
BTW,
you may refer to see-also Topic 235004, which mentioned that they can capture frames normally without enable embedded data.
that why I’m checking internally for SerDes chips with embedded metadata.
