Hi,

I want to load a USB FLASH with CY7C67300.

My CY7C67300 USB controller is on a daughter board with a CY7C1069
SRAM to support it.

I set the CY7C67300 in HPI mode (PIN 39 and 40 is low).

I can see the C67x00 driver is successfully loaded from the embedded
linux log.

But nothing happen if I plug in a USB FLASH.

I wonder whether I need a application to download to the CY7C67300
controller before I boot the system with embedded linux. And if I need
such an application, where can I find one?

Your help will be very appreciated!

Hi Peter, Thank you for your reply. I have enabled the USB mass storage. Below is the boot log. Any advise will be highly appreciated. setup_cpuinfo: initialising setup_cpuinfo: No PVR support in CPU.
