Hi All Can anyone tell me how to compile the kernel afer the step: $ mkdir fsl-release-bsp $ cd fsl-release-bsp $ git config --global user.name "Your Name" $ git config --global user.email "Your Email" $ repo init -u git://git.freescale.com/imx/fsl-arm-yocto-bsp.git -b imx-3.10.17-1.0.0_ga $ repo sync MACHINE=< machine name> source fsl-setup-release.sh -b -e bitbake core-image-base But the kernel i get doesnot support dvd-rom,it doesnot has /dev/sr0 or /dev/sg0 etc,so i want to compile the kernel again,but there is no the source code,in which can support the command make menuconfig. I follow the article <> as a reference.Any help would be preciated.
