If data is not being transmitted or received for the AXI4-Stream Interfaces, check the following conditions:
- If transmit
s_axi_tx_tready
is stuck Low following thes_axi_tx_tvalid
input being asserted, the core cannot send data. - If the receive
s_axi_tx_tvalid
is stuck Low, the core is not receiving data. - Check that the
user_clk
inputs are connected and toggling. - Check that the AXI4-Stream waveforms are being followed and check the core configuration.
