[ts-7000] ts-7250 based network camera, spca driver

["Felix Kharis Yohendi" <>]

hi all,

i'm new to embedded linux, this is my first project...
i am planning to build a web server that serves video/image stream
from usb-webcam on ts-7250. the webcam i planned to use is 
- logitech quickcam using quickcam(qce-usb) driver 320*240 or
- logitech communicate STX using spca driver 640*480

reading previous posts on this list, i've managed to compile and
install quickcam(qce-usb)
i've already success to grab images from quickcam using videodog.

but I got error messages when compiling spca5xx:

Linux kernel on ts-7250 2.4.26-ts9 NFS-ed to debian filesystem
woody-10-27-2005; gcc version is 3.0.4


can anyone help me on this? 
i also need comments on performance issue, since this is my first
project, :) i have no idea how much computing power does ts-7000 have.


i've also read on Message #3785 that recent version of the 2.4.26-ts9 
kernel code already has spca5xx code but i couldn't find it yet...


regards,

kharis
