Hi all,
I find abnormal behavior of chip which corrupts eth driver. In receive,
driver poll flag buffer empty and when buffer is not empty read receive
packet header form receive buffer. But after is last frame red, flag buffer
empty was false and driver try read next packet ( but that was no data ) and
lost synchronization. I add one more condition - I compare read and write
pointer of receive buffer from chip registers.
Any similar experience?
