i.MX6DQ Ethernet FCS Error counter

[mamorukanou]

Hi,

Is the judgment of the FCS error performed in the Ethernet MAC  HW of iMx6DQ?
If so, please tell us the register that sets the error count threshold.
If not, please tell me that.

Best Regards,

kanou

The ENET_IEEE_R_DROP register only counts the Rx frames with invalid or missing SFD character.

The Rx frames with invalid FCS are counted with the ENET_RMON_R_CRC_ALIGN register.

Have a great day,
Artur

I Change the way of my question.

i.MX6DQ has  "ENET_IEEE_R_DROP" register  related Ethernet.

* Frames not Counted Correctly Statistic Register（ENET_IEEE_R_DROP)

Counter increments if a frame with invalid or missing SFD character is detected and has been dropped. None of the other counters increments if this counter increments.

Question)

Does this counter include not only missing SFD(Start Frame Delimiter) character but also FCS(Frame Check Sequence) error count in Ethernet frame ?
