Hi Dirk, I am trying to add driver for sn9c102 based webcams. I have included all the srource files from directory l4/pkg/usb/examples/usbcam/contrib/linux/drivers/media/video/sn9c102 in MAKEFILE of SRC directory. In linking stage , it says that it cant find some refrences to param_set_bool' , 'vm_insert_page' , 'vmalloc_32_user' , 'dev_name', 'complete_all' .
Should I add some static library in makefile which I have found under SRC directory of USBCAM. Please notice that it is not giving any error in compiliation stage of diffferent object files. It gives error only in linking stage of usbcam.o .
Please help me .
Thanks Tapas

Hi Tapas,
You have incuded CPIA , GSPCA and UVC drivers in make file of SRC directory . I think that all the drivers that you have incuded in make file should work . Please correct me if I am not correct. The UVC driver for my laptop is not working . I am trying to make it work.
I tried the UVC driver, but unfortunately this driver does not support video capturing trough the read system call. To make it work you have to add the code for capturing video through shared memory. You should have a look into the the V4L2 documentation for that.
Ciao, Dirk.
hi all, I have succefully added new usb webcam driver support in my project. Thanks for helping.
Thanks Tapas

Hi Tapas,
You have incuded CPIA , GSPCA and UVC drivers in make file of SRC directory . I think that all the drivers that you have incuded in make file should work . Please correct me if I am not correct. The UVC driver for my laptop is not working . I am trying to make it work.
I tried the UVC driver, but unfortunately this driver does not support video capturing trough the read system call. To make it work you have to add the code for capturing video through shared memory. You should have a look into the the V4L2 documentation for that.
Ciao, Dirk.
Hi Tapas,
I have succefully added new usb webcam driver support in myproject. Thanks for helping.
Thats great. I'm glad to hear that. It would be cool if you could provide your patches to usbcam, so we also have support for this type of webcams. :o)
Ciao, Dirk
Hi Dirk, I want to thank you again for helping a lot. We have added a driver for sn9c102 webcams. I have tested this with my "Genius Videocam Messenger" webcam. We will provide the patches after completing our project. At present I am working to develop a better webcam viewer application and trying to store webcam video on hard disk.
It would be great if you could provide us following information :
1) How can I write a better webcam viewer application. I have seen your v4l2 and v4l1 viwer codes. But at present I dont know how to develop a better webcam viewer application. Could you please tell me what exactly "ioctl" function does in your webcam viewer application? I have seen that you have called this function recursively inside "ioctl" function in usbcam.c . 2) I am searching for a L4 IDE driver so that I can store video from webcam in my file system. But l4ide that I have downloaded from svn (svn version 447) has some build issues. I have tried to build that many times .But I have failed to build. I have described the problem here :
http://www.nabble.com/This-is-the-exact-error-message-which-I-have-got-when-... http://www.nabble.com/help-please...-L4-IDE-not-working-%21%21%21-td22968858...
Is there any way to build l4ide or l4ata successfully? If I get a driver to write in harddisk then it will make my life easier to develop filesystem support. Please help me .
Thanks Tapas
