Hi,
I'm new to OpenWrt so forgive some naive questions. I've installed latest WhiteRussian stable release on Asus WL-500gp. Unfortunately I've problems to follow a tutorial on webcam service. I've downloaded modules spca5xx, spca5xx_lite and the application spcacat. Module (full version) recognises camera correctly:

kernel: usb.c: registered new driver spca5xx
kernel: drivers/usb/spca5xx.c: USB SPCA5XX camera found. Type Vimicro Zc301P 0x303b
kernel: drivers/usb/spca5xx.c: [spca5xx_probe:8380] Camera type JPEG
kernel: drivers/usb/zc3xx.h: [zc3xx_config:415] Find Sensor HV7131R(c)
kernel: drivers/usb/spca5xx.c: [spca5xx_getcapability:2207] maxw 640 maxh 480 minw 176 minh 144
kernel: drivers/usb/spca5xx.c: spca5xx driver 00.57.07 registered

and device file /dev/v4l/video0 is created. I've linked this file to /dev/v0. Then command

root@OpenWrt:/mnt/disc0_1# spcacat -d /dev/v0 -s 640x480 -p 100 -N -o -f jpg

returns

and router reboots. Please help me to pinpoint a problem.
Using spca5xx_lite does not change anything ;( 

Thanks a lot for the suggestion. That combination works
OpenWrt:
insmod spca5xx_lite
servfox -d /dev/v0 -g -s 320x240 -w 7070
Laptop:
spcaview -w 192.168.1.1:7070
so the problem is with spcacat!
Are there any chances to force servfox to periodically dump frames to a specified file?
What can I do to debug spcacat? Maybe you have statically linked version of spcacat, too
