USB Superspeed Peripherals

New Contributor II

I had download 03/24/2016 


use fpga to creat data


the example is 8bit with 30fps works fine then i change to 16bit with 60fps still works fine


but when i change to 32bit (60fps and 120fps) the problem occur the data didn't transfer thought usb


follow the pdf i sure isDQ32bit is true both counters is 4091 and SPI is false


this is the list what i changed:


X,Y dimension ratio to 5:4


height to 1024


fps to 120


frame size to 2621440 (1280*1024*2)


which those in VS format descriptor / VS frame descriptor / UVC Probe control settings


In GPIF setting


change data bus width to 32bit


delete sensor_reset pin


change LD_data_counter/LD_addr_counter to 4091




So why this problem happen and whats special for 32bit mode?
