Dear Expert-team,

 

FEC_EIR[23](MII interrupt) rarely NOT assert when i.MX53 FEC MII data recieve (or read reg of PHY) completed.
If this happend, communication force disconnected.  It was clearly not satisfied our product requirements.

 

Why didn't FEC_EIR[23] flag changed?

Is there any workaround for this?

 

Thanks.
