Hi,
I have RZ/T1 CPU with Ethernet running on it. If I do a network burst the ETHERC stops receiving frames at some time, there is no data delivered to the application (ETHERC.BUFID.LONG returns buffer empty). When the error scenario occurs, both bits REMP (RX FIFO Almost Empty) and RFULL (RX FIFO Almost Full) in the GMAX_RXFIFO are set. The rx fifo cannot be almost empty and almost full at the same time! Is this a bug in the ethernet controller?
