[ts-7000] My ts7400 is taking pictures.

["Craig Hollabaugh" <>]

I have a Logitech USB QuickCam camera, ID 046d:092e. My desktop
running 2.6.23.x can acquire images via gspca from
http://mxhaard.free.fr/download.html.

But what about the ts7400 running 2.4.26-ts11 with the TS Debian SD card.

I extracted and configured the source in /usr/src/linux, remember to
'make dep'.
cd /usr/src/linux
make menuconfig
Multimedia devices -> <M> Video For Linux
make modules
insmod drivers/media/video/videodev.o

I extracted spca5xx-v4l1goodbye.tar.gz into /usr/src/spca5xx-v4l1goodbye
cd /usr/src/spca5xx-v4l1goodbye
I commented out 'CFLAGS += -mpreferred-stack-boundary=2' line, my gcc
3.3.6 was complaining about it.
make and take a break, the ts7400 isn't the speediest compiler
insmod spca5xx.o
dmesg
usb.c: registered new driver spca5xx
drivers/usb/spca5xx.c: USB SPCA5XX camera found.Logitech QuickCam chat

Hey, the driver found my camera.

Took an image with
vgrabbj -d /dev/video0 -f first.jpg

------------

My first insmod spca5xx.o failed with 'unresolved symbol' errors.

: insmod spca5xx.o
spca5xx.o: spca5xx.o: unresolved symbol video_devdata
spca5xx.o: spca5xx.o: unresolved symbol video_register_device
spca5xx.o: spca5xx.o: unresolved symbol video_unregister_device
spca5xx.o: spca5xx.o: unresolved symbol video_usercopy
spca5xx.o: spca5xx.o: unresolved symbol video_device_release
spca5xx.o: spca5xx.o: unresolved symbol video_device_alloc

I checked the kernel symbol table and found they existed but had
version info.

: grep video_devdata /proc/ksyms
d4062118 video_devdata_Ra6b6756c [videodev]

So I removed module versioning under 
'Loadable module support' -> [ ] Set version information on all module
symbols' then recompiled.
Checking the kernel symbol table again, this time no versioning.

: grep video_devdata /proc/ksyms
d4062118 video_devdata [videodev]

insmod spca5xx.o completed successfully.
