Fork of http://github.com/Aptina/BeagleBoard-xM ----------------------------------------------------------------------- | | |Aptina AR0130 (1.2 megapixel bayer) image sensor linux driver release | | | ----------------------------------------------------------------------- Release notes for the Aptina AR0130 image sensor linux driver. This document contains information on how to download the OS, build the driver/OS and how to use the sensor. Please read this document before posting questions to the [email protected] e-mail address. AR0130 Driver -------------- The AR0130 driver is a Video for Linux 2 (V4L2) driver that is compiled into the Overo Linux Angstrom distribution. It is distributed under the GNU General Public License agreement which can be obtained from Free Software Foundation, Inc., 675 Mass Ave, Cambridge, MA02139, USA. TARGET HARDWARE/SOFTWARE ------------------------ - Gumstix Overo. - Linux Angstrom Distribution, kernel release 3.5.7. - Aptina Beagleboard-xM Adapter/Revision 0 and AR0130 1.2-megapixel raw sensor. DRIVER SOURCE CODE FILES ------------------------ Driver files and directory locations are listed below: ar0130.c, ar0130_data.h, Makefile, and Kconfig are located at: git/drivers/media/video ar0130.h and v4l2-chip-ident.h are located at: git/include/media board-omap3beagle.c and board-omap3beagle-camera.c are located at: git/arch/arm/mach-omap2 LINUX KERNEL CONFIGURATION/COMPILATION -------------------------------------- Copy AR0130 related files into the kernel directories: $cp your_ar0130_driver_directory/board-omap3beagle.c ./arch/arm/mach-omap2 $cp your_ar0130_driver_directory/board-omap3beagle-camera.c ./arch/arm/mach-omap2 $cp your_ar0130_driver_directory/ar0130.c ./drivers/media/video $cp your_ar0130_driver_directory/ar0130_data.h ./drivers/media/video $cp your_ar0130_driver_directory/Makefile ./drivers/media/video $cp your_ar0130_driver_directory/Kconfig ./drivers/media/video $cp your_ar0130_driver_directory/ar0130.h ./include/media $cp your_ar0130_driver_directory/v4l2-chip-ident.h ./include/media From Yocto enter the command: bitbake -f -c menuconfig virtual/kernel In menuconfig, enable the AR0130 driver. The AR0130 driver configuration is at the following location: "Device Drivers"-->"Multimedia support"-->"Video capture adapters"-->"Encoders/decoders and other helper chips" Select "Aptina AR0130 support" as either <*> Aptina AR0130 support so that the driver is part of kernel image, or Note: other image sensors (such as the MT9V011 or MT9P012) should be de-selected. Compile the kernel: bitbake -f -c compile virtual/kernel AR0130 SUPPORTED OUTPUT FRAME SIZES ------------------------------------ width=640, height=360 width=640, height=480 width=1280, height=720 width=1280, height=960 AR0130 SUPPORTED OUTPUT FRAME FORMATS -------------------------------------- SRGB LIMITATIONS ----------- Preview resolutions less than 640x360 are not supported. AE is enabled by default. AWB and AF are not supported. KNOWN ISSUES ------------ The debugging feature "SYSFS" is not enabled. The default sensor setting support the Aptina camera adapter card (vs. the Leopard Imaging adapter card)
