中星微－龙眼摄像头（ZC03xx+MI0360）驱动移植
Kernel version :2.6.26.8
Crosstool    :arm-linux-gcc-3.4.1
Camera：ZC0301b+MI0360
一、移植gspcav1-20071224
gspcav1-20071224下载地址:
http://www.slackware.com/%7Ealien/slackbuilds/gspcav1/build/gspcav1-20071224.tar.gz
步骤1：
将gspcav1-20071224.tar.gz 复制到linux-kernel-dir/driver/media/video下并解压，重命名文件夹为：gspca
[root@localhost video]# cd gspca
[root@localhost gspca]# vi  Kconfig
添加:
config USB_SPCA5XX
      tristate "USB SPCA5XX Sunplus/Vimicro/Sonix jpeg Cameras"
      depends on USB && VIDEO_DEV
      ---help---
      Say Y or M here if you want to use one of these webcams:
      The built-in microphone is enabled by selecting USB Audio support.
      This driver uses the Video For Linux API. You must say Y or M to
      "Video For Linux" (under Character Devices) to use this driver.
      Information on this API and pointers to "v4l" programs may be found
      at .
      To compile this driver as a module, choose M here: the
      module will be called spca5xx.
[root@localhost gspca]# vi Makefile
添加:
gspca-objs := gspca_core.o decoder/gspcadecoder.o
obj-$(CONFIG_USB_SPCA5XX) += gspca.o
clean:
   rm -r -f *.o decoder/.gspcadecoder.o.cmd decoder/*.o
   .gspca.o.cmd  *.o *.ko *.mod.* .[a-z]* core *.i
   *.symvers *.err
步骤2：
[root@localhost gspca]# cd ..
[root@localhost video]# vi Makefile
添加:
obj-$(CONFIG_USB_SPCA5XX) += gspca/
[root@localhost video]# vi Kconfig
在if V4L_USB_DRIVERS && USB下面
添加:
source "drivers/media/video/gspca/Kconfig"
步骤3：gspca驱动源代码修改
1.
[root@localhost video]# cd gspca
[root@localhost gspca]# gedit zc3xx.h
在h:160找到函数:
static int zcxx_probeSensor(struct usb_spca50x *spca50x)
{
      …………
//增加这一句使下面的if语句满足条件,最后能够返回代表MI0360传感器的0x13
checkword = 0xc001;
PDEBUG(1, "sensor 3w Vga ??? 0x%04X ", (checkword & 0xffff)); //h:322
if (checkword == 0xc001 || checkword == 0xe001 || checkword == 0x8001) // h:323
{
………….
return 0x13;
}
…………
}
2.
在gspca目录下打开gspca_core.c，将h：3592改为：
//spca50x->sensor = SENSOR_PB0330;
spca50x->sensor = SENSOR_MI0360;
步骤4：make menuconfig
Device Drivers  --->
Multimedia devices --->
Video capture adapters  --->
V4L USB devices
   USB SPCA5XX Sunplus/Vimicro/Sonix jpeg Cameras
此时，可能会提示 gspca_core.c 的错误：
//static const char gspca_version[] = GSPCA_VERSION;
static const char gspca_version[] = "1.00.20";
把新生成的内核烧进开发板，重启，插上中星微芯片的摄像头，命令行出现
# usb 1-1: new full speed USB device using s3c2410-ohci and address 2
usb 1-1: configuration #1 chosen from 1 choice
drivers/usb/media/gspcav1-20071224/gspca_core.c: USB GSPCA camera found.(ZC3XX)
说明移植的驱动已经能识别设备，设备名所在路径 /dev/video0。

二、servfox
服务器端程序用是servfox，通过它可以在PC上看到开发板采集来的图像，从这里下载
http://mxhaard.free.fr/spca50x/embedded/Servfox/servfox-R1_1_3.tar.gz
下载，解压，进入其目录，发现没有一个makefile.arm，还有一个makefile.386，将makefile.arm改名为makefile，然后输入命令 make，生成 servfox 可实行文件，copy 到开发板运行之：
# ./servfox -d /dev/video0 -g -s 640x480 -w 7070
servfox version: 1.1.3 date: 11:12:2005 (C)
mxhaard@magic.fr

wrong spca5xx device
Waiting .... for connection. CTrl_c to stop !!!!
Got connection from 192.168.1.2
三、spcaview
客户端程序使用的是spcaview，下载地址为：
http://mxhaard.free.fr/spca50x/Download/spcaview-20061208.tar.gz
这个程序在PC 上运行，直接解压编译，生成 spcaview 可实行文件，运行如下：

[root@weijing spcaview-20061208]# ./spcaview -g -w 192.168.1.17
Spcaview version: 1.1.7 date: 06:11:2006 (C)
mxhaard@magic.fr
