If data is not being transmitted or received, check the following conditions:
• If transmit m_axis_tready is stuck low following the s_axis_tvalid input being asserted, the core cannot send data.
• If the receive s_axis_tvalid is stuck low, the core is not receiving data.
• Check that the ACLK inputs are connected and toggling.
• Check core configuration.
• Add appropriate core specific checks.
