2.3.3.OTG Stack
The OTG stack consists of the OTG driver. This driver maintains the OTG software FSM, and coordinates the host and device functionality switching. It interfaces with OTG applications through the Linux file system. For more information on this interface, refer to API ISP1362 OTG Stack.
2.4.Application Modules
2.4.1.Mass Storage Disk Emulation
This module is an application module and emulates a physical disk. It responds to a minimal set of
2.4.2.OTG Applications (OTG Mass Storage Demo/OTG Tools)
There are two OTG applications:
•A
•A
These applications are used to test the OTG mass storage functionality. These are written for the demo.
2.5.Porting Modules
2.5.1.Hardware Access Layer Driver
The core modules of the ISP1362 (Host Controller Driver, Device Controller Driver and OTG driver) communicate with the ISP1362 hardware through this driver. Since hardware access is mostly
2.5.2.Mass Storage Bridge
As physical storage disk is specific to the product, a mass storage bridge is needed. Also, as the mass storage disk is an emulator in the application space, this layer provides an interface to the application module. You need to port this layer to interface with the physical disk driver (kernel/application).
3. Installation
