执行TQ2440带的测试程序：usb摄像头抓取 失败

给开发板安上usb摄像头后 有如下提示信息：
[root@EmbedSky /mnt]# usb 1-1: new full speed USB device using s3c2410-ohci and address 5
usb 1-1: New USB device found, idVendor=0ac8, idProduct=3450
usb 1-1: New USB device strings: Mfr=1, Product=2, SerialNumber=0
usb 1-1: Product: Vimicro USB Camera (Altair)
usb 1-1: Manufacturer: Vimicro
usb 1-1: configuration #1 chosen from 1 choice
uvcvideo: Found UVC 1.00 device Vimicro USB Camera (Altair) (0ac8:3450)
input: Vimicro USB Camera (Altair) as /devices/platform/s3c2410-ohci/usb1/1-1/1-1:1.0/input/input4

然后执行spcacat -s 320*240 -p 100ms -N 1 -o命令 就会出现Illegal instruction的错误提示：

[root@EmbedSky /mnt]# spcacat -s 320*240 -p 100ms -N 1 -o
Illegal instruction
[root@EmbedSky /mnt]#

spcacat 只用在2.6.13.4内核。
