i'm tasked to make our fpga board (altera stratix ii with niosii core w/ microtronix uclinux version 1.4) able to write data out to a usb hard drive (like a lacie drive). the usb port is otg. currently, the driver for writing data out to the usb port has been written, but it doesn't have the mass-storage protocol yet. i was wondering where can i learn how to so (newbie to developing drivers)?
we use cast usb core. when i boot up the uclinux, this is the message we are getting. (just fyi ..if it provides any info about our board at all)
