Hi Laurent, I have a beagle xm board, but no sensor board. Is it possible to have the omap3-isp initialised ? I would like to try my program on a beagle board to eliminate any hardware related problem. >From the board file in mainline kernel, it seems omap3_init_camera is not called, do you know any kernel tree where isp is initialized for beagle board ?
