Depends on the rootfs image you are building. Most images that are based on core-image-base will take care of deploying necessary pieces into the rootfs. But core-image-minimal is special and very bare-bone, so extra manual steps are required. Regardless of the rootfs image, you'd need MLO and u-boot.img to be located in the first FAT partition of your SD card or eMMC flash. Then, if your rootfs does not already have zImage and the necessary DTB files in the /boot directory, you have to place them there (i.e. core-image-minimal) and you are ready to boot. All the defaults will work for out-of-the-box in this case. No uEnv.txt is necessary, unless you need to do something extra special... -- Denys -- _______________________________________________ meta-ti mailing list [email protected] https://lists.yoctoproject.org/listinfo/meta-ti
