    Receive "CYU3P_PIB_ERR_THR1_RD_UNDERRUN" when write to FPGA

    zqli_4003376

      Hi,

      I got continued "CYU3P_PIB_ERR_THR1_RD_UNDERRUN" flag when wrote about 200K data to FPGA with below setting:

      GPIF:32bit

      DMA buffer size:16384

      DMA count:4

      host write 16384 every time

       

      Could U help to explain this?
