Currently, I'm using the Innovator SDK which has the OMAP 1510 processor from TI. I am using the v4l2-omap driver which came with ARM9 kernel. I can aquire a frame of video from the camera with no problem, but when I enable the preview mode using an ioctl call to the v4l2-omap driver, I get an error that the frame buffer cannot be opened (fb0). Note that I can open the frame buffer (fb0) with no problem from an application. The v4l2 driver is using a sys_open to open up the frame buffer device, but the sys_open call returns with an error. Any ideas why this is not working. My area is in signal processing and I'm just starting to get into linux. Thanks for any help. Ron
