This is best combined with piping into less (or the pager of your choice) and then searching for the modified values, like SRC_URI. If more than one recipe is involved, things can be complicated, and overwrite each other. bbappend actually have the desired effect? This will give you a complete and detailed list of all appends that are in effect in your current build situation. While this seems to be the case for you (you found out through the debug output) this is usually easier checked with: bitbake-layers show-appends But there's a couple of obstacles to watch out for, respectively things to check: Technically the process you described sounds correct to me. I have not tried suggestion 2 as the first method sounded better. the adjusted auto-boot delay I put in the patch was used in u-boot-imx). Here's my u-boot-imx_2017.03.bbappend FILESEXTRAPATHS_prepend := "$/configs - so bitbake knows where to apply the patch, i.e. I created a new layer with a u-boot-imx_2017.03.bbappend to extend u-boot-imx_2017.03.bb (the recipe for u-boot-imx). config file, and copied it to my layer and renamed to "defconfig". I followed this guide for kernel configuration with the Yocto project. There are many xxx_defconfig files and I don't know which it is using. find the build directory and run make menuconfig), but when I run bitbake to rebuild the image, it overwrites the. change the auto boot delay to 1 second as an example. config used to build u-boot-imx (u-boot for the iMX dev board) - e.g. Building linux for an iMX6 dev board using the Yocto Project, and I want to change the.
