Is a receive buffer overflow a real error? I would say not. But it would be good to count it. There was also the open question, what exactly does a receive buffer overflow mean? The spec says: 9.2.8.11 RXBOE Receive Buffer Overflow Error. When set, this bit indicates that the receive buffer (from the network) has overflowed and receive frame data was lost. Which is a bit ambiguous. I would hope it means the receiver has dropped the packet. It will not be passed to the host. But other than maybe count it, i don't think there is anything to do. But Ramón was suggesting you actually drop the frame currently be transferred over the SPI bus? Andrew
