Hi,


May I know is this one time random failure event or you can somehow consistently reproduce the error every 4 hours or after some specific event/operation occurs ?

  • Can you also elaborate further on the failure description ?
  • Did you saw corrupted packet, lost of packet or application software stuck/hang issue ?


Can you explain more on your Ethernet hardware setup ? Any block diagram to share ?

  • What TSE IP variance is set ?
  • How does your TSE IP connect to PC ?


Below is some debug suggestion.


Thanks.


Regards,

dlim

hi Dlim

I am using TSE ip 18.1 version. The above problem is a random failure does not happen after a particular cycle. Never experience loss of packet or corrupted packet. It looks more like a hang issue. The Max10 IP core is connected to processor through PHY device(KSZ8081MNXIA-TR).

The Ethernet resumes after reset is pressed sometimes but sometimes does not resume operation even after a power cycle.

The rx_err[5:0] signal has been monitored but it does not show any errors so far in my observation.
