--------------------------------------------------------- Microframework → μfw → ufw — Embedded Support Library --------------------------------------------------------- ‘ufw’ is a support library for embedded development. It started out as a sand- box for trying implementions or various kinds. It then quickly became a reser- voir for various utilities that come in handy when building modular embedded applications: Version control integration; CMake build system extensions and embedded toolchain files; zephyr impedance mismatch management; a very portable implementation of a TAP emitting testing API; startup code and a cortex-m3 to run test-suites for this architecture via qemu; toolchain feature testing and portable enabling, and more. Commonly, ‘ufw’ is part of a larger source-tree that leverages it to build em- bedded applications. It is also possible to build ‘ufw’ using many toolchains, build-tools, build configurations and the like. To automate the required cmake incantations, you can use the library's companion tool ‘mmh’: % mmh …builds as many combinations of ‘ufw’ as it can and reports the results. All build results will be cleaned up afterwards. % mmh -d ci …will do the same, but perform all builds inside the ’ci’ subdirectory and will keep it around after all work is done. You can also select parts of all combi- nations of builds: % mmh -d ci -T clang,gnu -A native -B ninja -C debug …only builds ‘ufw’ using the ‘clang’ and ‘gnu’ toolchains in ‘debug’ configura- tion using the ‘ninja’ build tool. While this: % mmh -d ci -T gnu-arm-none-eabi -A cortex-m3 -B ninja -C debug …builds the library for the ‘cortex-m3’ architecture in ‘debug’ configuration using ‘ninja’. If a ‘system-arm’ qemu implementation is found on the host sys- tem, ufw's cortex-m3 startup code is used to run the library's test-suite via qemu.
