product-specific. Therefore, this driver communicates with a mass storage bridge (portable). For more information on the device stack interface, refer to API ISP1362 Device Stack.

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 SCSI-II commands, and uses a file system interface to store the physical disk data. This is developed for the OTG mass storage demo purpose.

2.4.2.OTG Applications (OTG Mass Storage Demo/OTG Tools)

There are two OTG applications:

•A GUI-based application (for PC evaluation kits only)

•A command-line-based application

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 platform-dependent, this module must be ported to the target platform. This driver provides an interface to the ISP1362 registers and buffers, to the ISP1362 I/O ports and interrupts, and configures the ISP1362 based on the platform.

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

The ISP1362 evaluation boards are available in the following platforms:

•ISP1362 PCI evaluation kit

•ISP1362 ISA evaluation kit

•ISP1362 add-on card for Intel PXA250-based Accelent® IDPTM.

The ISP1362 Linux stack currently supports the ISP1362 PCI evaluation kit and ISP1362 add-on card for Accelent IDP. Support for other platforms will soon be added to the stack. The same source code will work for all platforms by changing the compile time options. The following diagram shows the evaluation kit setup example for the ISP1362 Linux stack.
