In that case you can switch to the DMA Mode of SPI operation. Please refer the example: C:\Program Files (x86)\Cypress\EZ-USB FX3 SDK\1.3\firmware\serialif_examples\cyfxusbspidmamode

Hi Madhu Sudhan,
I tried running the SPI DMA mode example. I assume it needs USB control center to send data from PC to CX3. I tried sending data with it. However, it resulted in "CONTROL OUT transfer failed with Error Code:997" . When I selected Interface0/alternate setting 0, it popped up a message asking to select bulk/iso/interrupt endpoint from the device tree. If I am doing wrongly, Please explain how to make this example work using control center.
