-# Operating System Abstraction Layer Project
+# Core Flight System : Framework : Operating System Abstraction Layer
 
-![OSAL Logo by Michael Cudmore](./doc/OSAL-Logo.png)
+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>.
 
 ## Version History
 
+### Development Build: 5.0.21
+
+- Command line options in Linux are no longer ignored/dropped.
+- No impact to current unit testing which runs UT assert as a standalone app. Add a position independent code (PIC) variant of the ut_assert library, which can be dynamically loaded into other applications rather than running as a standalone OSAL application. This enables loading
+UT assert as a CFE library.
+- Unit tests pass on RTEMS.
+- Resolve inconsistency in how the stack size is treated across different OS implemntations. With this change the user-requested size is passed through to the underlying OS without an enforced minimum. An additional sanity check is added at the shared layer to ensure that the stack size is never passed as 0.
+- Update Licenses for Apache 2.0
+- See <https://github.com/nasa/osal/pull/521>
 
 ### Development Build: 5.0.20

 - This is a point release from an internal repository
 
-# 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:
+# Quick Start:
 
-```
-export OSAL_SRC = /home/acudmore/osal/src
-```
-
-In build/osal-config.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):
 ```
-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.)
+mkdir build_osal
+cd build_osal
+cmake -DOSAL_SYSTEM_BSPTYPE=generic-linux ..
+make
 ```
 
-Optional: Some Linux systems may require an additional linker option in src/bsp/pc-linux/make/link-rules.mak:
-
+OSAL permissive build with tests example (see also [CI](https://github.com/nasa/osal/blob/master/.travis.yml))
 ```
-LDFLAGS ?= $(OSAL_M32) -export-dynamic
-
-If the symbol-api-test fails, then you need this option.
+mkdir build_osal_test
+cd build_osal_test
+cmake -DENABLE_UNIT_TESTS=true -DOSAL_SYSTEM_BSPTYPE=generic-linux -DOSAL_CONFIG_DEBUG_PERMISSIVE_MODE=TRUE ..
+make
+make test
 ```
 
-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 the [Configuration Guide](https://github.com/nasa/osal/blob/master/doc/OSAL-Configuration-guide.pdf) for more information.
 
-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.
+See also the autogenerated user's guide: <https://github.com/nasa/cFS/blob/gh-pages/OSAL_Users_Guide.pdf>
 
-If you would like just the OSAL itself, just look in src/os/inc for the include files and src/os/
+## Known issues
 
-<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.
