X-BeenThere: yocto@yoctoproject.org X-Mailman-Version: 2.1.13 Precedence: list List-Id: Discussion of all things Yocto Project List-Unsubscribe: , List-Archive: List-Post: List-Help: List-Subscribe: , X-List-Received-Date: Wed, 09 Dec 2015 10:36:32 -0000 Content-Type: text/plain; charset=US-ASCII short version: with a short BSP layer i've been handed, the eventual kernel .config file ends up with the setting: CONFIG_WIRELESS=y which makes no sense as the target board has no wireless and the BSP itself doesn't set that, so how can i start tracking back to figure out where that particular setting came from? long version: i'm actually using Wind River Linux 7, but the question remains the same. it turns out that CONFIG_WIRELESS is selected by CONFIG_WLAN, so i'm really after what sets CONFIG_WLAN. i don't see it in the BSP layer, so i'm tracing back to the WR kernel recipe, and possibly features templates and any other kernel .cfg snippets i can find, so far with no luck. in either case, is there a log file that lists *precisely* which kernel config snippets contributed to the final .config file? thanks. rday -- ======================================================================== Robert P.
