Then use make command to build system images, images will be generated in out/target/product/sabresd_6dq. If you want to rebuild u-boot or kernel, use commands below: ./clean6dqbootimg.sh make bootimage && make recoveryimage && make U-boot source directory is vendor/nxp-opensource/uboot-imx, and kernel is vendor/nxp-opensource/kernel_imx. You can replace them with your own. But if you want to use different defconfig file or device tree, you may need to edit device/fsl/sabresd_6dq/BoardConfig.mk. ==etc info== ==overclocking== http://www.udoo.org/forum/udoo-mx6-overclocked-2ghz-t596.html https://community.freescale.com/thread/314572 ===key benefits=== * existing lvds, existing HDMI * mipi, csi interfaces for camera * consumer levels, industrial levels and automobile levels. * sata connection. * hardware accelerated video encoding/decoding ==Aimx6 Coreboard Hardwire Error== ===A3=== [[File:Imx6 a3 fixup.jpg|500px|right]] 1.
