Errors while Executing video application on ARM processor,
Hi,
This is my first post in this forum.
I am using a USB webcam from Logitech QuickCam Connect .I have downloaded the gspca-20071224 tar file,as it is supporting my Webcam(after checking the product ID and vendor ID).I am trying this USB webcam to work on ARM9(SL3516) processor.After cross compiling and porting the module, i am able to detect my USB webcam as " JPEG camera".
As an application,i have downloaded spcaview-2006108 and i am able develop spcacat,spcasev executables.These are the applications which are supported by this driver which i have downloaded.
while running this command:
spcaserv -d /dev/video0 320*240 -w 30 -f yuv
i am getting error: "Error in opening V4L interface".I checked with dmesg command:
I am getting this messages:
"/source/gspcav1-20071224/gspca_core.c:init isoc:usb_submit_urb(0) ret -38"
split I/O support disabled"
After googling and reading some discussions, i have came to know that:
error -38 is ENOSYS comming from the usb layer, and the the Webcam driver writer has suggested to change the USB socket.
Earlier i have this webcam works fine on my host linux system,with same driver (normal compilation) and checked with Camstream application.
I have asked my vendor telling my above problems,he told me that there USB(2.0) is supporting high speed mode not full speed mode and they have checked another USB webcam V-UAR38 from logitech,and it works fine on my ARM SBC.
What can be the reason of my Logitech Quickcam connect not giving me proper outputs?
I need your support for these problems.
Thanks & Regards,
Ravi Chobey
