Yes, the CMO build machine would have to be configured.

So, steps 3 through 6 are implicit. I create the working directory by unpacking the original ltib skeleton. At that point, everything is there (including the packages in the LPP) and I can run LTIB interactively. However, I do not see how to run it without user interaction. I have tried various combinations of "-b" and "--preconfig" with various saved configurations files. But I can't seem to get the magic set. Below are some that I have tried (ltib/ is a saved run and ../ltib is the fresh working copy): cp .ltibrc ../ltib cp ltib/config/main.lkc ../ltib/config/ cp ltib/.config ../ltib/ cp ltib/config/.config ../ltib/config/ cp ltib/config/platform/imx/.config ../ltib/config/platform/imx/ cp ltib/config/platform/imx/defconfig.dev ../ltib/config/platform/imx/ cp ltib/config/platform/imx/imx6_defconfig.dev ../ltib/config/platform/imx/imx6_defconfig I am not sure which of these files I need, if I left out some crucial ones or included some that cause problems. 3.3.042312
