Hi Jerome,

The only registers I have are those below and I don't see which one could correspond to the edgecapture register.

The line "IOWR(video_in_base[0], 0x0, 0x08 )" enables the interruption. I tried to put it in the ISR but no more success.

# define VIDEO_1_NAME "/dev/video_1"# define VIDEO_1_TYPE "bitec_qvideo_in"# define VIDEO_1_BASE 0x00008000# define VIDEO_1_SPAN 128# define VIDEO_1_IRQ 1# define ALT_MODULE_CLASS_video_1 bitec_qvideo_in

Given the registers, do you have an idea ?

Thank you for your help,

Myriam
