Please do let me know if there is any method to update firmware on cypress CY7C67300.
What do you meant by update firmware? Do you want to modify firmware? If yes, its possible. Please detail your requirement.
I work with xupv5 xilinx board. This board has cypress (cy7c67300) chip on it. I want to attach usb mass storage to usb port on xupv5 board and perform read/write with it. Xilinx has a keyboard sample that this sample has it's firmware, but I didn't have any firmware that work with usb mass storage. Can anyone help me?
