Hello,
I am unable to verify the known udp data packet I am sending to the W5200. The RX size is correct and the RX RD pointer is 0. The physical address of the RX data has been calculated correctly however the data is not corresponding to what I expected.
I have tried to write to the RX Buffer and then read back the data and have found it does not correspond as well, however writing to the TX buffer and reading corresponds. Is the RX buffer RD only? Is there an extra step required before accessin the RD buffer?
