• If using the AXI4-Stream interface, make sure to write data correctly. The most common mistake is to assume words are written without looking at s_axi_tx_tready . Also remember that the s_axi_tx_tkeep signal must be used to indicate which bytes are valid when s_axi_tx_tlast is asserted.
• Ensure to read correctly from the RX interface. Data and framing signals are only valid when m_axi_rx_tvalid is asserted.
