2Product Overview

Quectel UC20 is a wireless WCDMA modem. You can use it to implement some functions such as VOICE

CALL and browsing internet and so on.

In general, the UC20 module will create five interfaces when you connect it with embedded equipments.

These five interfaces have different functionalities. The details are shown as below:

3System Setup

Linux OS includes a generic USB to serial driver for modem. You can make the UC20 module available in

the Embedded Linux OS by adding some kernel configuration items and adding the information (VID/PID)

in Linux kernel.

The first part of this chapter is to describe the structure of Linux USB Driver and the rest is to explain how

to build the USB driver for UC20 module.

3.1. Linux USB Driver Structure

USB is a kind of hierarchical bus structure. The data transmission between USB devices and Host is

achieved by USB Controller. The following picture illustrates the architecture of USB Driver. Linux USB

Host driver includes three parts: USB Host Controller driver, USB core and USB device drivers.

The USB Host Controller driver, the bottom of the hierarchical structure, is a software module which

interacts directly with hardware.

USB core, the core of the whole USB host driver, is responsible for the management of USB bus, USB

bus devices, and USB bus bandwidth, providing the interfaces for USB device driver, through which the

applications can access the USB system files.

USB device drivers interact with the applications, and mainly provide the interfaces for accessing the

specific USB devices.

3.2. Building the Driver

During the development based on embedded Linux OS, you must retrieve the Linux kernel source code

files and install an appropriate cross compiler first, then modify the kernel configuration and

corresponding source code files, and compile the kernel to generate image file, then burn the file into the

target machine (The OS of the target machine is Android 4.0.3, and the corresponding Linux kernel

version is 3.0.8).The detailed steps are shown as below:

3.2.1. Install Cross Compiler

Cross-compilation is an important technology for embedded development. Its feature is that the source

code files are not compiled in native machine but the other one. In general we call the former target

machine and the latter host machine.

The reason of adopting cross-compilation is that most embedded target system cannot provide enough

resources for compiling source code files, so we have to do that in a high-performance host machine in

which we will create an environment of cross-compilation for the target machine.

In general, the vendor of the embedded machine would provide the cross compiler and the installment

method about it. Here, we use the cross compiler "arm-linux-gcc-4.5.1", install it and add the compiler’s

path in the system environment variables, then re-logout system, then you can use the cross compiler to

compile the source code files.

3.2.2. Modify the Source Code File of Linux Kernel

Modify the source code file "option.c" in Linux kernel by adding VID and PID of UC20, so that the OS can

recognize it.
