Hi,
I started a project that requires to connect a webcam and an arduino board to the router (WL-520GU). I don't have yet the arduino board, so right now I'm trying to figure out the webcam thing.

I read everything I found about installing a webcam under OpenWrt, I flashed my router at least 20 times with different versions of openwrt to try different versions of spca5xx files I found on the internet, and so far, after 3 days I couldn't make it work. The farthest I got is that when I plug in the camera, I get the message:

I'm stuck. I need help.
Some questions:
1) do I need to compile spca5xx for openwrt version that I use or the spca5xx.o files I find on the internet should work fine?
2) if I need to compile the spca5xx, how to I do that? I built openwrt from the source, but I have no idea how to include (or just compile separately) spca5xx
3) did I get the wrong router? will the webcam work on my router?

I don't know if this will help, but here is the dmesg:

Thanks.

I have had problems with spca webcams (and don't know enough to have figured out the solutions--I'm sure they are there).  But I have a UVC webcam running now on a WL-520GU, a Rosewill RCM-3201V (available now in the U.S. at Newegg: http://www.newegg.com/Product/Product.a … -_-Product )

The quickcam deluxe for notebooks also works, and I'm sure the quickcam 9000 would.  I was hopeful about a <$10 UVC webcam from dealextreme, but it apparently doesn't stream encoded mjpeg, only raw format.

For software, I'm using mjpg-streamer, with the necessary usb, usb2, usb audio kmods.

If you're building your own and don't have kmod-video-gspca in your "makemenu config", have you tried to "./scripts/feeds install kmod-video-gspca" to include it?

Is there a list somewhere with all the packages that can be included with "./scripts/feeds install ..."? I see a directory named "spca5xx-le" in /feeds/packages/multimedia/  but if I run "./scripts/feeds install spca5xx-le" I get "No feed for package 'spca5xx-le' found, maybe it's already part of standard packages?

I'm getting same thing for "./scripts/feeds install kmod-video-gspca".

The camera I'm trying to use, a refurbished Creative Instant,  is $7.99 at Fry's and is supposed to be supported by spca5xx-le.

Thanks.

"./scripts/feeds install kmod-video-spca5xx-le" runs without error for me from the build directory.  But it does not appear as an entry in menuconfig, so I searched: "/spca5", and it shows up and is selected by "PACKAGE_spca5xx-view".  It also indicates that it depends on Linux 2.6.24 or 25 or 26--I haven't seen that before and am not certain what it means for this build.  But I could not find spca5xx-view, so I don't know what you would need to do next.

It is amazing that the se401 driver isn't longer supported by OpenWRT, yet the se041 driver source codes are still distributed under linux-2.6.30.

I have good news.
I was able to compile the latest openwrt source kernel 2.4 with spca5xx as a package.
The webcam works without problems now on my WL-520GU. Again, the webcam I'm using is a $7.99 camera from Fry's, refurbished Creative Instant.
I will post detailed instructions on how I compiled the source and how I applied the spca5xx-le patch if anyone is interested.
If anyone want it already built, here are the binaries:
http://ioanghip.googlepages.com/openwrt … pca5xx.zip

Please do post.

To compile openwrt latest source with spca5xx-le patch you will need a Linux box.
I'm using vmware image of ubuntu on a windows machine with vmware player installed. I downloaded the vmware image from here: http://repository.variableadmin.com/vm/ … desktop.7z

Here is how you do it:
Open a console and type:

Select the following options:

Save the configuration and then type in console:

This will take a while...
When is done, type this in console:

Now we have to modify usb.mk. Open with a text editor ~/kamikaze/package/kernel/modules/usb.mk and add the following code to it:

Save usb.mk with the new settings.

Now we have to build the image again. In Kernel->modules->USB Supoprt you'll have a new line "kmod-usb-spca5xx", make sure is marked as [M].

Save the new config, and then:

The compiling stopped twice to ask me to to select an option, I selected "m".

When is done, you'll have in ~/kamikaze/bin/brcm-2.4/ the new firmware:
openwrt-brcm-2.4-squashfs.trx
and in ~/kamikaze/bin/brcm-2.4/packages/ the compiled spca5xx package:
kmod-usb-spca5xx_2.4.37.5-1_brcm-2.4.ipk

Let me know if you have questions or if something is not clear.

Thanks very much for the detailed flow.  I'll have to study this.

Great How To, it really helped me out!

I installed the kmod, ran "insmod spca5xx", and added a symbolic link (ln -s /dev/v4l/video0 /dev/video0).

It works great with spcacat, although that particular webcam only does 352 x 288. 

Thanks again!

Any idea why a Logitech quickcam for notebook deluxe webcam would not work with the above setup?  I got the author's webcam to work and wanted to improve the resolution, so I bought the logitech as it is supposed to supported by the same spca5xxLE driver and have 640x480 resolution.

Here is my dmesg output.

 usb.c: registered new driver spca5xx
spca_core.c: spca5xx driver 00.57.06LE registered
usb.c: USB disconnect on device 00:03.0-1 address 2
hub.c: new USB device 00:03.0-1, assigned address 3
usb.c: USB device 3 (vend/prod 0x46d/0x8d8) is not claimed by any active driver.

Any help would be appreciated!

Thanks!

Thanks for the package file and the comprehensive how-to. I am using an ASUS WL500 GPV2 router (very similar in hardware to the 520 GU), with the brcm-2.4 Kamikaze Bleeding edge running on it.
I downloaded your ipk file to my router, however when i tried to install, this was the error I got:

root@OpenWrt: opkg install kmod-usb-spca5xx_2.4.37.5-1_brcm-2.4.ipk
Collected errors:
* Packages were found, but none compatible with the architectures configured

Not sure why it is complaining about the architecture in this case. Am i doing something stupid or would it only be possible to work around this by compiling my own package. Others have been succesful in installing this, so I was wondering if anyone had a similar problem.

What version of Kamikaze were you running during this?

Also a bit worried about the use of the Logitech Communicate STX [046d:08d7] which is shown to be supported by spca5xx/LE. Would I require any changes to the way you built the package for this particular cam ?

Thanks for the help

Thank you very much.

Now a day, you can not update another package with 'opkg install'. Because old-trunked compiled package was gone from server. So, you need to re-build it all.

After that , I have tried to run 'motion', motion detection software.
But there's some problem.
Because motion could not initial '/dev/v4l/video0'.

So, I'm still looking for next solution.

Yup...Quite a good news that is.
Please keep us posted.

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

Here is the archive containing makefile from 2nd and the result (spca5xx.o):

http://www.tempfiles.net/download/20110 … /asus.html

1st: I tried also to compile on the router the drivers:
http://mxhaard.free.fr/spca50x/Download … bye.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

- appeared the message: `vlan1: dev_set_allmulti(master, 1)`;
- no video0 in /dev (nor /dev/4l/video0);
- no other errors, no tained, no unresolved symbols;
- there are no files in /proc/video nor /proc/spca50x

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 Sad

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

P.S.: the Logitech STX cam it's recognized under CentOs 5.5 and works perfectly with Palantir 2.7...

hello ioan,
this is a romanian name
Did you succed to solve 5xx-LE issue with webcam?
I also have many webcams which might work with this driver but i cannot find it in backfire repository.
any ideea?
brgds,
Sebastian
viosebi@yahoo.com

Kernel 2.6 has better suport for web cams.
Also, try JPEG webcams to function correctly.
