| # Operating System Abstraction Layer Project | ||
| # Core Flight System : Framework : Operating System Abstraction Layer | ||
|
|
||
|  | ||
| This repository contains NASA's Operating System Abstraction Layer (OSAL), which is a framework component of the Core Flight System. | ||
|
|
||
| The OS Abstraction Layer was originally devloped by the Flight Software Systems Branch at NASA Goddard Space Flight Center. | ||
| This is a collection of abstractio APIs and associated framework to be located in the `osal` subdirectory of a cFS Mission Tree. The Core Flight System is bundled at <https://github.com/nasa/cFS>, which includes build and execution instructions. | ||
|
|
||
| # OS Abstraction Layer information: | ||
|
|
||
| This distribution contains: | ||
|
|
||
| 1. The OS Abstraction Layer Library | ||
| 2. Tests and example applications | ||
| 3. A directory structure and makefiles to manage it all. | ||
| The autogenerated OSAL user's guide can be viewed at <https://github.com/nasa/cFS/blob/gh-pages/OSAL_Users_Guide.pdf>. | ||

| # Getting Started: | ||
|
|
||
| See the document _doc/OSAL-Configuration-Guide.doc_ for complete details. | ||
|
|
||
| See User's Guide: <https://github.com/nasa/cFS/blob/gh-pages/OSAL_Users_Guide.pdf> | ||
|
|
||
| An easy way to get started is to use the Linux port and classic build: | ||
|
|
||
| 1. Set the _OSAL_SRC_ environment variable to point to the OSAL source code. | ||
|
|
||
| - Running setvars.sh will set the variable for you ($source ./setvars.sh) | ||
|
|
||
| 2. Edit the _build/osal-config.mak_ file and set the following options: | ||
|
|
||
| - BSP - Set this to the board you are running on. For a PC running linux, use _pc-linux_ | ||
| - OS - Set this to the OS you are running. For a PC running linux, use _posix_. | ||
| - OSAL_M32 - Uncomment/Add this build variable for building 32-bit images using "native" GCC on a 64-bit X86 Linux platform | ||
|
|
||
| Buiding on a PC running linux: | ||
|
|
||
| ``` | ||
| export OSAL_SRC = /home/acudmore/osal/src | ||
| ``` | ||
|
|
||
| In build/osal-config.mak: | ||
|
|
||
| ``` | ||
| OS=posix | ||
| BSP=pc-linux | ||
| Optional: OSAL_M32 = -m32 (Note: Usage of this flag may require an optional 'multilib' (or similar) | ||
| package to be installed. Refer to your operating system and toolchain documentation for details, if | ||
| adding the appropriate flag causes your builds to fail due to (for example) missing 32-bit or | ||
| multilib related headers or libraries.) | ||
| ``` | ||
| # Quick Start: | ||
|
|
||
| Optional: Some Linux systems may require an additional linker option in src/bsp/pc-linux/make/link-rules.mak: | ||
| Typically OSAL is built and tested as part of cFS as detailed in: [cFS repo](https://github.com/nasa/cFS) | ||
|
|
||
| OSAL library build pc-linux example (from the base osal directory): | ||
| ``` | ||
| LDFLAGS ?= $(OSAL_M32) -export-dynamic | ||
| If the symbol-api-test fails, then you need this option. | ||
| mkdir build_osal | ||
| cd build_osal | ||
| cmake -DOSAL_SYSTEM_OSTYPE=pc-linux -DOSAL_SYSTEM_BSPTYPE=pc-linux -DOSAL_INCLUDEDIR=src/bsp/pc-linux/config/ .. | ||
| make | ||
| ``` | ||
| See the [Configuration Guide](https://github.com/nasa/osal/blob/master/doc/OSAL-Configuration-guide.pdf) for more information. | ||
|
|
||
| Now just type _make config; make_ from the build directory and it should build the OSAL core files, tests, and sample applications for you. The binary for each application is in its own directory (i.e. build/examples/tasking-example/tasking-example.bin) You can switch to that directory and run it. You can also debug it using GDB. | ||
|
|
||
| NOTE: Running on linux may require root or adjusting the posix message queue maximum sizes. | ||
| See also the autogenerated user's guide: <https://github.com/nasa/cFS/blob/gh-pages/OSAL_Users_Guide.pdf> | ||
|
|
||
| The Embedded targets take a little more work to run, because they must be cross compiled and booted on the board. By copying a target, you should be able to come up with a new target. | ||
| ## Known issues | ||
|
|
||
| If you would like just the OSAL itself, just look in src/os/inc for the include files and src/os/ | ||
|
|
||
| <your os="" here=""> | ||
| for the OSAL implementation.</your> | ||
|
|
||
| The API documentation is in the _doc_ directory. | ||
|
|
||
| There are two sets of tests: build/tests and build/unit-tests. To build and the unit tests, perform the build steps above then _make unit-tests_ in the build directory. | ||
|
|
||
| Instructions on how to use the newely supported cmake build system are provided in the OSAL Configuration Guide located in the _doc_ directory. | ||
