I've configured and build linux kernell for OMAP L138, as it describes here: http://processors.wiki.ti.com/index.php/MCSDK_OMAPL138_User_Guide_Chapter_Exploring#Overview
Then I'm build examples for VPIF, provided with PSP 03.21.00.04.
But when I'm booting my linux on OMAP-L138 LCSDK with following bootargs: vpif_capture.ch0_bufsize=831488 vpif_display.ch2_bufsize=831488, and trying to captured video stream from my analog cam, connected to composite in, by running command ./vpif_mmap_loopback -m 1 -p 0, it shows an following error:
_________________________________________________________
root@omapl138-lcdk:~/vpif# ./vpif_mmap_loopback -m 1 -p 0
Cannot open = /dev/video0 device
Error in opening capture device for channel 0.
____________________________________________________________________________
As I understand my camera should to be identifired as video device in /dev/video0. But it didn't happen.
Can anybody help me, what am is supposed to do to fix this problem?
