Transplantation of adding the 3G wireless network interface card function on the MIPs embedded platform (I)

I. Environment

1. Linux kernel of the Development Board: 2.6.28.10

2.3G wireless network adapter: Huawei E303 (vendorid: 12d1 productid: 14fe)

 

Ii. related software:

1.usb-modeswitch-1.1.7.tar: USB device Working Mode Conversion Tool

2.usb-modeswitch-data-20110227.tar: used to configure usb_modeswitch.conf

3.libusb-1.0.8.tar: provides a set of system APIs for usb_modeswitch.

4.libusb-compat-0.1.3.tar: compatible with version 1.0 and 0.1

Iii. Description:

• 1. Pay attention to parameter settings when configuring. Configure for libusb-1.0.8 and libusb-compat-0.1.3 (specify cross compiler, specify size side settings ):

#. /Configure -- Build = i686-linux -- Host = MIPS-Linux-GNU -- prefix =/home/WSL/libusb-1.0.8/install "cc = MIPS-Linux-GNU-El" "ldflags =- el"

• 2. Note the following when modifying the MAKEFILE file in USB-modeswitch (Modify the bold part.):

Cc = MIPS-Linux-GNU-gcc
Cflags + =-wall-El
Libs =-lusb-1.0-lusb
Rm =/bin/Rm-F
Objs = usb_modeswitch.c
Prefix = $ (destdir)/usr
Etcdir = $ (destdir)/etc
Udevdir = $ (destdir)/lib/udev
Sbindir = $ (prefix)/sbin
Mandir = $(prefix)/share/man/Man1

Libdir2 =-L/home/WSL/libusb-compat-0.1.3/install/lib

. Phony: clean install uninstall

$ (Prog): $ (objs)
$ (Cc)$ (Includedir1) $ (includedir2) $ (libdir1) $ (libdir2)-O $ (Prog) $ (objs) $ (cflags) $ (libs) $ (ldflags)

• 3. Edit the usb_modeswitch.conf file in the usb_modeswitch directory and add the following content:

# T-Mobile NL (Huawei e352)
#
# Contributor: Alex Hermann

Defaultvendor = 0x12d1
Defaultproduct = 0x14fe

Targetvendor = 0x12d1
Targetproduct = 0x1506

Messagecontent = "55534243123456780000000000000011062000000100000000000000000000"

Messageendpoint = 0x01

Checksuccess = 5

Required weimode = 0

• 4. Copy the above libusb dynamic library and libusb-compat (under Lib) to the Development Board library directory (/LIB, download the above generated usb_modeswitch executable program (no file type) and usb_modeswitch.conf configuration file to a directory on the Development Board (which is also executed in this place when execution is executed.

• 5. Compile the driver option of the 3G module. ko: device Drivers ---> USB support ---> <m> USB serial converter support ---> [*] USB generic serial driverh and <m> USB driver for GSM and CDMA modems "must be compiled into modules, ttyusb0, ttyusb1, and ttyusb2 can be generated during subsequent conversions.

Find the USB 3g driver file driver // USB/serial/option. c In the kernel source package, and add the required wei_product_ec1260 0x1446 to the 3G card. Return to the kernel top-level directory make modules and compile usbserial and option into modules usbserial. Ko and option. Ko. Download the compiled usbserial. Ko and option. Ko to the Development Board and load them using insmod.

• 6. Now you can useUsb_modeswitch-C ~ /Usb_modeswitch.confSwitch the 3G card mode. There will be some information, you will see several serial information after converting to 3G mode, ttyusb0, ttyusb1, ttyusb2

(Print the following results. I do not know whether the result is successful or not)

Print the above results. I do not know whether it is successful or not, but I have no 3G wireless network card that can be paid online. The experiment can only be stopped here, further research is required.

In fact, the driver comes with the kernel, and it is OK to compile it. The key is to convert the default storage mode to the 3G mode, today, the conversion is successful, and the process is recorded.

Detailed solution for 3G cards on the Development Board in Linux (applicable to most 3g cards) _ Linux programming _ Linux community-portal website usb_modeswitch is a universal tool for converting the working mode of USB devices, only in Linux can it play a huge role. With the development of mobile communication and wireless communication, more and more devices are made into USB interfaces, such as some wireless network adapters and 3G data cards. Manufacturers of these devices generally provide drivers in windows. When these devices are plugged in for the first time, they are in the CDROM + flash mode, from which drivers can be installed, after the driver is installed, the driver will be converted to the 3G mode, and a usb modem device will appear. Currently, all 3g cards are like this. This is the so-called & ldquo; zerocd & rdquo ;.
