Hi, The default TX buffer for N32x is 128k samples = 512 kB. The box has 1 GB of DRAM. I am getting occasional underflows when streaming at 200 Msps, even though the CPU is not very loaded and easily meets the average throughput.
I have done all the usual stuff — isolated cores, pin threads to cores, etc. Is there a way to increase the default DRAM buffer size w/out rebuilding the FPGA image? Thanks. Eugene Grayver, Ph.D. Principal Engineer 310-336-1274
