2.1.Overview

The ISP1362 is a single-chip Universal Serial Bus (USB) On-The-Go (OTG) Controller integrated with the USB Host Controller and the USB Device Controller. The ISP1362 Linux stack is the software for the ISP1362 evaluation kit that operates as an OTG mass storage device.

Using the ISP1362 Linux stack, the ISP1362 can function as:

A standard USB full-speed mass storage device when connected to a PC running any OS

A USB full-speed OTG mass storage device when connected to any OTG device

A USB host when connected to USB peripherals (OTG and non OTG).

The ISP1362 Linux stack is a group of kernel and application modules arranged such that the code can be easily ported to any other platform running the Linux OS. All the platform-specific modules are made as separate modules. Besides, the ISP1362 Linux stack can be used as reference code to build OTG device firmware. The ISP1362 Linux stack is distributed with the complete source code files.

2.2.Stack Architecture

Figure 2-1 shows the software model of the ISP1362 Linux stack. The software stack consists of three modules, shown in three colors:

Core modules (these modules are platform-independent)

Application demo modules

Porting modules (these are platform-specific or product-specific modules that require porting).

The following subsections briefly explain each module.
