Compiling driver for webcam

[raas]

Hi,

some changes, I still haven't figured out why it doesn't work with the pre-boot script (the file is executable), but when I run it by hand ('registering' the spca5xx.o)
the last lines of dmesg looks like this

usb.c: registered new driver spca5xx
drivers/usb/spca5xx.c: spca5xx driver 00.60.00 registered
usb.c: USB disconnect on device 01:03.0-1 address 2
hub.c: new USB device 01:03.0-1, assigned address 3
usb.c: USB device 3 (vend/prod 0x46d/0x920) is not claimed by any active driver.
[admin@NAS root]$

as you can see the driver is registered, but the driver doesn't recognize the camera? do I need an other driver or ??? i don't get it.

[dyonisos]

Does the webcam work at all? Have you tried it on a different Linux and/or Windows system? The spca5xx driver you have should be working.

[raas]

hehe.. smart thinking, dyonisos,
I got the webcam from a friend.. it is used.. but it is supposed to work.
haven't tried it on an normal pc though, but will do this tonight.

Thanks for your suggestion.

quickcam pro 4000 is working for me, but I think it is using a different driver.
I think you need the pwc driver

insmod videodev
insmod pwc
insmod pwcx

is this working?

[raas]

dyonisis and wpte, thanks for your reply.

I've tried the webcam on my pc, but no luck,
The webcam didn't came with a box, so I had to retrieve model/driver through a number on the webcam: V/UAL-9 this pointed me in the direction that it is a quickcam express. the picuter of a quickcam express looks like my cam, So I suppose this is the cam..

DL'd and installed the drivers, but when I connect the webcam, the logitech software doesn't detect it.. That's strange.. it looks like the webcam isn't working, perhaps it's broken, but that's strange, 'cause this friend of mine used it, and put it away working.

However, If I don't get it to work on a pc, I don't think it will work on the asus (indeed dyonisis)...
Will fidle around with it to see if i can get it to work.

you probably need an old driver, they are not really downloadable on logitechs website anymore, but some google will help you out
I had it too with an old logitech one, doesnt work on the new drivers, but the old ones work perfectly

[Tamadite]

I have found the following page have the source code for the Logitech webcam I have.

http://qce-ga.sourceforge.net/

Will I get the webcam to work with router's web interface by just complying the drivers? In other words, is router's web interface directly connected to the already defined drivers or will it work as soon as the device get claimed by the driver?

(Why I do not try it? Because I want to avoid dedicating several hours to set up an WL-500gP compiling environment in vain)

(Why I do not try it? Because I want to avoid dedicating several hours to set up an WL-500gP compiling environment in vain)

not sure if it directly works...

and on the setup... including installing linux (like ubuntu) well... an hour or so for beginners
compiling is usually max. 30min depending on your pc

making things easier:
for software you need this:

build-essential
libncurses-dev
gawk
flex
bison
zlib-dev
subversion

build essential contains all the build software

also don't forget to sudo things when they don't work
you could also make /opt as your own so you don't need sudo-ing all the time:

sudo chown yourusername:root -R /opt

the rest is just follow the instructions on the wiki: http://code.google.com/p/wl500g/wiki...CustomFirmware

I manage to compile the driver targeting my x86 under Ubuntu but I can't get Makefile to compile for MIPSEL. There is no CC or CPP variable I can set as:

CC = mipsel-linux-gcc
CPP = mipsel-linux-gcc -E

This is the Makefile that comes with version 0.6.6-6 of the driver.

#
# Makefile for the qc-usb driver (based on Linux Philips USB Webcam driver)
#
# NOTE: This make file can serve as both an external Makefile (launched
#       directly by the user), or as the sub-dir Makefile used by the kernel
#       build system.

# If CONFIG_USB_QC isn't set, we'll assume the user want to build this driver has a module

ifndef CONFIG_USB_QC
CONFIG_USB_QC=m
endif

ifneq ($(KERNELRELEASE),)

quickcam-objs   := qc-driver.o qc-hdcs.o qc-pb0100.o qc-vv6410.o
quickcam-objs   += qc-formats.o qc-mjpeg.o qc-memory.o

obj-$(CONFIG_USB_QC) += quickcam.o

EXTRA_CFLAGS=-Wall -I$(PWD) -DNOKERNEL

else
ifndef KVER
KVER  := $(shell uname -r)
endif
KLINK := $(shell test -e /lib/modules/${KVER}/source/ && echo source || echo "build")
ifndef KSRC
KSRC  := /lib/modules/$(KVER)/$(KLINK)
endif
KMISC := /lib/modules/$(KVER)/drivers/media/video/
PWD := $(shell pwd)

all default:
        $(MAKE) -C $(KSRC) SUBDIRS=$(PWD) modules

install: default
        install -d $(DESTDIR)/$(KMISC)
        install -m 644 -c quickcam.ko $(DESTDIR)/$(KMISC)

uninstall:
        -rm -rf $(DESTDIR)/$(KMISC)/quickcam.ko

clean:
        rm -f *.[oas] .*.flags *.ko .*.cmd .*.d .*.tmp *.mod.c
        rm -rf .tmp_versions qcset

CFLAGS ?= -Wall -O2

qcset: qcset.c quickcam.h
        $(CC) $(CFLAGS) $(LDFLAGS) -o $@ -lm $<
endif

any idea?

This is the Makefile that comes with version 0.6.6-6 of the driver.

any idea?

Unfortunately, Makefile above, don't ready for cross-compiling. You have to rewrite some parts of it.

[Tamadite]

You have to rewrite some parts of it.

That's not an option for me right now since my knowledge on this matter is quite limited.

If the Makefile is not ready for cross-compiling, will I get it to work if I try to compile it directly on the router?

You need the kernel headers for that I believe... so that will also be a bit problematic.
furthermore the driver will be compiled with the optware uclibc, which is older than the firmware uclibc. so that might cause trouble as well when you want to use it

If you want driver for "classic" Oleg FW 1.9.2.7-10, it compiled already - http://translate.google.com/translat...n&hl=&ie=UTF-8 (google autotranslate).

If you want to compile it for 1.9.2.7-d, you should:

1. build firmware from SVN first
2. setup proper LINUX_DIR
3. replace CC = mipsel-linux-gcc to CC = mipsel-linux-gcc-3.4.6

NB! Anyway, driver can be buggy

[kolaCZek]

Please,
can enyone built spca5xx driver for 1.9.2.7-d ?

[fukushimaku]

Hello,

I read from a lot of threads on different forums about
spca5xx but no results... I think I have 3 choices:

1st: compile the module onto router using actual compiler
2nd: cross-compilling the module on a pc machine
3rd: compile using same gcc version 3.2.3 with Broadcom
modifications from Asus directly to router

I attached here the makefile from 2nd and the result (spca5xx.o).


1st: I tried also to compile on the router the drivers:
http://mxhaard.free.fr/spca50x/Downl...goodbye.tar.gz

- system: Broadcom BCM4704 chip rev 9 pkg 0;
- cpu: BCM3302 V0.6;
- Linux version 2.4.20 (gcc version 3.2.3 with Broadcom modifications) #109;
- firmware 1.9.2.7-10-USB-1.71 (from koppel.cz);
- webcam Logitech, Inc. QuickCam Communicate STX; ID: 046d:08d7;
- compiler: gcc version 4.1.1;
- linker: gnu ld version 2.17.50.0.8 20061201
(both installed with ipkg on /opt/ [compact flash, 16gb card])

At compilation process everything seems to stuck at /opt/include/asm/softirq.h
The output of `make` is:

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

2nd: I downloaded that version from the Asus's site
(and also the source of firmware: GPL_WL500GP_1.9.7.7.tar.gz and toolschain323.tar.gz),
extracted into pc#2 with CentOS 5.5, and configured in Makefile from spca5xx-v4l1goodbye.tar.gz
I compiled it after many struggles. Only few warnings and no error (see below):

3rd: very slow (you know already the deal with the router's limited cpu, ram)...
so: no problem at `configure`, errors at `make`... still working at it...
don't know if I will see it finaly and properly compiled

I really don't still want to get to 2.6.x kernel; after few months maybe.
I appreciate every single advice in this problem.
