One of my customer experience a problem on the RM57L843,they do the network storm test recently, they found that after injection 10Mb/s unicast traffic to the network card, the hardware will not response the receive interrupt(The variable countEMACCore0RxIsr in the ISR function does not increase).
when the unicast traffic was removed, the MCU cannot recover.In the meantime, the Network Ping impassability.
