- Check if fetch crediting is enabled or not (See Credit Descriptor Context Structure); the user logic is required to provide a credit for each descriptor that should be fetched.
- Make sure the hardware and credit context are cleared before enabling the queue.
- Check PIDX and CIDX values. Make sure there are enough descriptors.
- QDMA Driver failed to load (qdma:qdma_device_online: qdma_init failed -16.)
- Make sure to connect st_rx_msg_rdy, tm_dsc_sts_rdy and soft_reset_n to 1'b1
- tm_dsc_sts_error reports error in h2c direction. The issue seems to occur after the first PIDX update write to QDMA.
- Make sure the Ring Size configuration is done correctly.
- C2H Hang
- Confirm C2H transfer is hitting 4K boundery in host memory when the hang occurs.
- Make sure s_axis_c2h_tready and s_axis_c2h_cmpt_tready signal are toggling correctly.
- Check if it is dependent on number of queues active when the hang occurs.
- QDMA IP not detected in lspci
- Check the following signals in ILA:
- user_link_up, axi_aresetn, soft_reset_n, phy_ready
- QDMA Driver failed to load (qdma:qdma_device_online: qdma_init failed -16.)
