Hi All,A newbie question: After creating a new bsp for an Overo using the yocto-bsp script and modifying some kernel config's using menuconfig, I successfully created and loaded the image (core-image-minimal) onto an SD card and booted it. However, I do not see the kernel emitting any boot messages. Am I forgetting to include some recipes?
