Specifies the path to a log file into which BitBake’s user interface writes output during the build. BitBake User Manual If doing so results in unnecessary rebuilds of tasks, you can whitelist the variable so that the setscene code ignores the dependency when it creates checksums. There also needs to be a way for each recipe to express its dependencies, both for build-time and runtime. Bitbake ===== BitBake is a generic task execution engine that allows shell and Python tasks to be run efficiently and in parallel while working within complex inter-task dependency constraints.

The value is not set when the task is in server context during parsing or bitbaie handling. It is extremely difficult to leave it before concluding, once you begin to read the book.
To be able to run BitBake from any directory, you need to add the executable binary to your binary to your shell’s environment PATH variable. I added the CONFIG_CMD_MEMTEST in platform-top.h and I have verified that it adds that u-boot command when in the prompt which performs a simple ram test. documentation: Updated the manual revision history tables for 1.6.1; ref-manual: Fixed a link to the BitBake User Manual. Causes the fetcher to only checkout mabual specified directory with no recurse into any subdirectories. Assuming BitBake has been instructed to execute a target and that all the recipe files have been parsed, BitBake starts to figure out how to build the target. We are going to import additional layers, so create a subdir to hold all of the layers that we import with git-subtree. Contains a space-separated list of all of all files that BitBake’s parser included during parsing of the current file. Although the syntax varies depending on the packaging format, BitBake hides these differences from you.
This allows you to, at any time, go to the command line and execute direct bitbake commands. The XCDL project defines and implements a component framework, as a set of metadata and a collection of tools specifically designed to configure and build complex, package based, multi-variant (multi-architecture, multi-board, multi-toolchain) embedded projects.
