Hi,

FX3S can support GPIF of 16 bit only. If you load a firmware with GPIF 32 bits enabled it will run into error state and it will stuck there forever and hence it will stop enumeration.

Hi geetha,

Please check your design according to AN70707. We also provide the schematic/PCB files for CYUSB3KIT-003.

You could also review your design taking these as reference.

FX3S is for storage application. Why do you test it with slave FIFO firmware?

Can you send your firmware in this discussion? But I am not sure if I could find CYUSB3035 board to dobule check.
