core Flight System (cFS) Scheduler Application (SCH) | ||
Open Source Release Readme | ||
|
||
SCH Release 2.2.0 | ||
|
||
Date: | ||
February 27, 2015 | ||
|
||
Introduction: | ||
The Scheduler application (SCH) is a core Flight System (cFS) application | ||
that is a plug in to the Core Flight Executive (cFE) component of the cFS. | ||
|
||
The cFS is a platform and project independent reusable software framework and | ||
set of reusable applications developed by NASA Goddard Space Flight Center. | ||
This framework is used as the basis for the flight software for satellite data | ||
systems and instruments, but can be used on other embedded systems. More | ||
information on the cFS can be found at http://cfs.gsfc.nasa.gov | ||
|
||
The SCH application provides a method of generating software bus messages | ||
at pre-determined timing intervals. This allows the system to operate in a | ||
Time Division Multiplexed (TDM) fashion with deterministic behavior. The TDM | ||
major frame is defined by the Major Time Synchronization Signal used by the | ||
cFE TIME Services (typically 1 Hz) and the Minor Frame timing is defined | ||
via a SCH Configuration Parameter that identifies the number of Minor Frame | ||
Slots that are executed within each Major Frame. | ||
|
||
The SCH application is written in C and depends on the cFS Operating System | ||
Abstraction Layer (OSAL) and cFE components. To build and run the SCH | ||
application, follow the cFS Deployment Guide instructions contained in | ||
cFE-6.4.1-OSS-release/docs. There is additional SCH application specific | ||
configuration information contained in the application user's guide | ||
available in cfs-sch-2.2.0-OSS-release/docs/users_guide | ||
|
||
There are also "Quick start" instructions provided in | ||
cFE-6.4.1-OSS-release/cfe-OSS-readme.txt | ||
|
||
The OSAL is available at http://sourceforge.net/projects/osal/ and | ||
github.com/nasa/ | ||
|
||
The cFE is available at http://sourceforge.net/projects/coreflightexec | ||
|
||
This software is licensed under the NASA Open Source Agreement. | ||
http://ti.arc.nasa.gov/opensource/nosa | ||
|
||
|
||
Software Included: | ||
Scheduler application (SCH) 2.2.0 | ||
|
||
|
||
Software Required: | ||
|
||
Operating System Abstraction Layer 4.1.1 or higher can be | ||
obtained at http://sourceforge.net/projects/osal or | ||
github.com/nasa/osal | ||
|
||
core Flight Executive 6.4.1 or higher can be obtained at | ||
http://sorceforge.net/projects/coreflightexec | ||
|
||
|
||
Runtime Targets Supported: | ||
The "out of the box" targets in the cFE 6.4.1 distribution include: | ||
1. 32 bit x86 Linux ( CentOS 6.x ) | ||
2. Motorola MCP750 PowerPC vxWorks 6.4 | ||
|
||
Other targets: | ||
Other targets are included, but may take additional work to | ||
run. They are included as examples of other target | ||
environments. | ||
1. mcf5235-rtems - This is for the Axiom MCF5235 Coldfire board running | ||
RTEMS 4.10. It requires a static loader component for the | ||
OS abstraction layer. The static loader is currently | ||
not available as open source, so this target is not | ||
considered complete. RTEMS 4.11 will have a dynamic | ||
loader which will be supported by a future release | ||
of the OS Abstraction Layer, completing the RTEMS support | ||
for the cFE. | ||
|
||
Once RTEMS 4.11 is released, the goal is to support | ||
an RTEMS simulator platform such as SPARC/sis or | ||
quemu. | ||
|
||
2. mac-osx and pc-cygwin - These targets are included for examples. They | ||
will most likely be removed in the future. | ||
The pc-linux target is highly recommended. If you | ||
have a windows or mac computer it is relatively easy to | ||
set up a free virtual machine environment with 32 bit | ||
Cent OS 5.x. | ||
|
