Thanks Bruce, how can I "check to see if the kernel options were picked up and made it to the build by looking at the linux build directory and the .config, are you options present in the final .config ?" have read the "development manual", in chap.4.1.2.2 said ".config file found in the Build Directory at tmp/sysroots/<machine-name>/kernel" but there's no "kernel" folder in my "tmp/sysroots/jasperforest" , nor in "tmp/sysroots/x86_64"
