    CYUSB.net EPIN bulk XferData Stuck with C++ streamer : prominently CYUSB driver issue

    user_250395407

      C++ streamer (EPIN bulk) failed with Altera FPGA writer using a FIFO writing at low clock speed <1MHz and 'slavefifosync' as CYUSB firmware

         

      XferData fails after few 1024KB EPIN Xfer due to HOST non-retry after NRDY condition found on USB traces.

         

      NB : XferData runs OK at high clock speed (100MHz)

         

      See doc attached for detailed description with USB traces taken with LECROY Advisor T3
