一.Compile kernel

1.修改driver自動bind

vi /drivers/usb/serial/option.c
#define HUAWEI_VENDOR_ID                        0x12D1
#define HUAWEI_PRODUCT_E169                     0x1001

static const struct usb_device_id option_ids[] = {
       { USB_DEVICE(HUAWEI_VENDOR_ID, HUAWEI_PRODUCT_E169) },


 

2.compile kernel

export PATH=$PATH:/your toolchain path

make ARCH=arm CROSS_COMPILE=arm-linux-gnueabihf- tisdk_am335x-evm_defconfig

make ARCH=arm CROSS_COMPILE=arm-linux-gnueabihf- menuconfig

make ARCH=arm CROSS_COMPILE=arm-linux-gnueabihf-


 

二.Compile usb_modeswitch

 

 

wget http://www.draisberghof.de/usb_modeswitch/usb-modeswitch-2.5.2.tar.bz2
 

修改makefile:

CC          = arm-linux-gnueabihf-gcc
INCLUDEDIR = /yourpath/usr/include/libusb-1.0
LIBDIR = /yourpath/lib
$(CC) -I$(INCLUDEDIR) -L$(LIBDIR) -o $(PROG) $(OBJS) $(CFLAGS) $(LIBS) $(LDFLAGS)


 

make

usb_modeswitch to /bin

usb_modeswitch.conf to /etc

 

三.Compile pppd

wget https://download.samba.org/pub/ppp/ppp-2.4.5.tar.gz

./configure
make CC=arm-linux-gnueabihf-gcc

cp pppd/pppd
cp chat/chat
cp pppdump/pppdump
cp pppstats/pppstats



 

四.確認USB Dongle正常

 

1001lsusb

剛接上dongle 裝置是 0685:7000 ZD Incorporated HSDPA Modem

lsusb
Bus 001 Device 005: ID 0685:7000 ZD Incorporated HSDPA Modem
Bus 001 Device 001: ID 1d6b:0002 Linux Foundation 2.0 root hub

 

一段時間自動抓取後，會變成

12d1:1001 Huawei Technologies Co., Ltd. E169/E620/E800 HSDPA

 

lsusb
Bus 001 Device 027: ID 12d1:1001 Huawei Technologies Co., Ltd. E169/E620/E800 HSDPA Modem
Bus 001 Device 001: ID 1d6b:0002 Linux Foundation 2.0 root hub

 

這也是不需要usb_modeswitch的原因

 

ls dev

觀察一下dev，會發現ttyUSB0-3，就是USB Dongle

ls /dev |grep USB
ttyUSB0
ttyUSB1
ttyUSB2
ttyUSB3

 

基本上 usb driver option 有修改都會有，如果沒有可能是沒有修改，

可以測試以下方式

echo 12d1 1001 > /sys/bus/usb-serial/drivers/option1/new_id

 

或是

 

echo 12d1 1001 > /sys/bus/usb-serial/drivers/generic/new_id

 

基本上使用generic driver 也可以，因為測試過


 

測試裝置正不正常

 

microcom /dev/ttyUSB0
ATZ
OK

 

OR

 

echo -e "AT\r" > /dev/ttyUSB0
cat /dev/ttyUSB0


 

測試SIM卡是否可以上網

echo -e "AT+COPS?\r" > /dev/ttyUSB0
cat /dev/ttyUSB0
+COPS: 0,1,"Chunghwa",2

 

如果返回0 ， 可能PINCODE 沒有開

echo -e "AT+CPIN=\"0000\"\r" > /dev/ttyUSB0


 

測試訊號強度

echo -e "AT+CSQ\r" > /dev/ttyUSB0
