Hi,
I've managed to take some steps backwards with my rfnoc work. In a test using the ADDSUB block and looking at packet sizes I see a maximum of 2000 samples per packet reported by the streamer, and 8058 byte packets received in wireshark. In my block I count valid's to assert tlast, and have been using 256 samples with "sideband at end". However, it seems I cannot increase that counter to 1024 samples where I get these errors (even if I set the streamer SPP to 1024): [ERROR] [STREAMER] The receive transport caught a value exception. ValueError: Bad CHDR header or invalid packet length. (Strangely, I still get the 1024-sample packets according to wireshark, so I guess its not related to the firmware?) BTW in my noc shell I have an MTU of 10, and have axis_data_to_chdr fifo's of 2048 samples. What do I need to do to ensure I can also get large packets out of my block, as smaller blocks are causing dropped packet headaches? Many thanks, Kevin
