Hi Geetha,
How are you planning to read back the storage card? I assume that you want to store the image sensor data on the SD card, then why you want your device to act as a UVC class device. Your firmware has to load "fatfs" on the SD Card. Please refer to "C:\Program Files (x86)\Cypress\EZ-USB FX3 SDK\1.3\firmware\storage_examples\cyfx3s_fatfs" firmware example.
Please note that if your device comes up as a mass storage device then host will itself load the file system on the SD Card.
Thanks & Regards

Hi,
Yes you can store video data into the SD Card via storage port. You have to create a DMA channel from P Port to S port and also maintain the appropriate DMA buffer size so as avoid overflow.
