Hi, I have a custom RFNoC resampler block that works with a simple RX flowgraph but not with a TX flowgraph. In the TX case, the radio transmits for a split second and then stops transmitting. If I try to run anything on the radio after, it fails with the following error, and I have to power cycle the radio for it to work again:
RuntimeError: EnvironmentError: IOError: Block ctrl (CE_00_Port_30) no response packet - AssertionError: bool(buff) in uint64_t ctrl_iface_impl::wait_for_ack(bool) at /... /rfnoc/src/uhd/host/lib/rfnoc/ctrl_iface.cpp:197 The flowgraph for RX is Radio-DDC-resampler-sink, and the TX flowgraph is Signal source-FIFO-resampler-DUC-Radio. I'm using the axi_rate_change block to handle the rate change my resampler introduces, and it looks like the header fifo in the axi_rate_change block gets full and causes the pipeline to lock up when I run my TX flowgraph, but everything runs fine in RX. Are there any differences between RX and TX in RFNoC that might explain why my block works in one case but not the other? Thanks, Jessica
