Compiling driver for webcam

[WlanMan]

Hi

Olegs tarrball is a patch to to the original asus tarball, this one carys crosscompiler toolchain and the stuff youre missing. The SPCA driver is not stable on mips, you can try it by searching he forum for it. It seems to have a memory leak, it eats up your memory until kernel gets panic and starts killing processes...
Does the NX cam works good on your linux box ? i have one of these ultra integrated spca webcams sold at around 12$ or so, and these are not well supported (Edit: OK, new drivers seem to habe better spca561 support, have to try again ).

...on my linux box that is.

I havent yet tried to cross-compile for mipsel

Hello,

I'm testing spca50x.o driver for webcam and it seem work fine with videodog and i will hope to compile myself.

I got sources from http://mxhaard.free.fr/download.html and i compiled them with cross compilation tools (already used to oleg's firmware with successful)
but in this case i have too many errors.

I would be very interested to get these sources of spca50x.o or if anybody has succeeds with http://mxhaard.free.fr/spca50x/Downl...0060501.tar.gz
then if you can explain what have you patched.

[vampire]

Yep, I'll be real keen to test the latest (and perhaps final for 2.4 acording to the site) driver out too if someone manages to compile it, the last spca driver i got that worked with my webcam was var:57.02. Camera detected as "USB SPCA5XX camera found. Type Flexcam 100 (SPCA561A)" (a cheap $15 NZD camera) and it worked.

Hi

Did anyone successfully build theese drivers for Olegs firmware? :

http://linux-uvc.berlios.de/

[dyonisos]

Can you please help me with a step by step guide how to compile the pwc 10.0.12 webcam driver into Oleg 1927-7g FW?
Or, if available, could you please provide me with the compiled 10.0.12 pwc module for wl-500g Premium, so that I can use my Philips SPC900NC? Thanks!

[geezerpl]

I'd love too to know how to do it (and why Oleg won't implement the newest driver in his FW ?) ?
Many thanks !

[raas]

....... (and why Oleg won't implement the newest driver in his FW ?) ?
Many thanks !

Probably because there's limited amount of space in the flash memory to store all the goodies we want..

(The flash size of the chip where the firmware is stored is 4mb, Oleg has a 'hell-of-a-job' to put everything he needs into this space)

and why are some older FW from asus 7 meg?

There is no step-by step guide, since that action assumes that you have some knowledge in writing/compiling/building C/C++ programs.

First of all, you have to read this:
Recompiling firmware

After successful custom firmware build, you should try two choices:
1) apply patches on kernel and make modules.
2) modify Makefile from pwc-10.0.12-rc1.tar.bz2 for cross-compiling and make it

In all cases, it is possible that you see some compilation errors. IMHO nobody can give to you universal solution.

Since pwc-10.0.12 is not released for 2.4.20 kernel, I apologize that Oleg simply hasn't enough resources for it adaptation & tests.

[al37919]

in principle, there is also a toolchain for native compilation on the router using built in libraries: http://wl500g.info/showpost.php?p=75208&postcount=11

However, there is no howto.

Hello, I have problem with this driver on WL-500gP. (Oleg WL500gp-1.9.2.7-9)

insmode is done in post-boot - driver is registered, but webcam is not recognized.
Is something need to change in config (webinterface) ?

Can somebody help me ?

Hi, I want to connect my logitech quickcam express to the asus.
having found on the forum, I have to use spca5xx.o for this.
according to the site of mxhaard http://mxhaard.free.fr/spca5xx.html I have to use this driver for this.

I have placed spca5xx.o in the flash under /usr/local/modules/spca5xx.o
and I do a /usr/local/modules/spca5xx.o in the pre-boot file.
however, if I (un)plug the device, it does not get recognised.

esp. the last lines

what am I doing wrong here?
and, if this is solved, how to continue.?

TIA

[wirespot]

All I see in your log is the webcam being connected and disconnected.

You need to load the module, not run it:

insmod spcaxxx.o

[raas]

Hello wirespot, thanks for your reply,

that was a typo i did.. in the pre-boot I do a

insmod /usr/local/modules/spca5xx.o

(like you said)

however I doesn't seem to run,

After a reboot I issued

insmod /usr/local/modules/spca5xx.o

in an ssh session manually, it returns with a promt (if I do it again, there's a message it's already there)

After that I posted the output of dmesg
(after I first (un)plugged the camera several times)


could there be something wrong with the spca5xx.o?
I got it from http://www.wl500g.info/showthread.ph...ight=spca5xx.o

Any ideas?
