Hi, I am having trouble running the FFT block of size 1024 on an N310. I am using the "rfnoc_rx_to_file" example program (UHD v3.14.1.0) to run it. It works with size 256 or 512. Additionally, I am able to run with 1024 if I switch to an X310 (same PC). Please let me know if you have any ideas... Rob
*Here is the command that fails:* rfnoc_rx_to_file --args="type=n3xx" --nsamps=65536 --block-id=FFT_0 --block-args="spp=1024" --rate=125e6 --freq=2400e6 --radio-args="spp=1024" *The following is the output with error message:* Using radio 0, channel 0 Setting RX Rate: 125.000000 Msps... Actual RX Rate: 125.000000 Msps... Setting RX Freq: 2400.000000 MHz... Actual RX Freq: 2400.000000 MHz...
