I am trying to develop an application running on a MC52259 which can provide a RAM disk to a PC through the USB interface. I have the MFS example RAM disk from MQX 3.5.1 running and can see the RAM disk and control it through the shell. I also have the USB device disk example running, and can see the device enumerate on my PC. However, there is no example I can find which will tie the USB driver to the RAM disk driver. The Disk_App() function in the example code is blank. Is there another example I can use?
