RTSC / XDC (eXpanDed C) is a standard for reusable software components, optimized for real-time embedded systems. RTSC components have hardware-neutral formal interfaces, are configurable offline to optimize memory and performance, and support custom automation in the development environment via a scripting language.
XDCtools 3.15.04.70 is the General Availability release of XDCtools 3.15.03
The XDCtools product includes the following sets of packages:
The product documentation for this release is available in two formats:
Both formats are delivered with the product in the docs subdirectory. The most up-to-date docs can also be viewed on-line at:
Release notes from previous product releases are available in the relnotes_archive directory.
XDCtools contains elements released under the Eclipse Public License v1.0 and a number of other open-source licenses, detailed here.
The following significant changes are included in 3.15.04.70:
The following significant changes were included in 3.15.00.50:
XDCtools now integrates with Code Composer Studio v4 (CCSv4) IDE and is bundled with the CCSv4 product. Users can build and run applications that use RTSC content in an integrated graphical environment.
The integration features include:
CCSv4 now includes a graphical wizard for creating RTSC platforms. This allows users who have their own hardware to generate a RTSC platform package that fully supports all RTSC command-line and graphical features.
CCSv4 now includes a graphical editor for RTSC configuration (.cfg) files. Features of the Graphical configuration editor include:
The graphical editor has beta status.
Error messages printed by XDCtools are now more concise, and stack backtraces are no longer printed by default. A new Trace facility lets package writers output debug information, and lets users filter the trace output according to producer and verbosity.
The trace support is documented on the web here.
XDCtools now includes runtime support for OS-related primitives, delivered as a standard part of the XDC Runtime in package xdc.runtime.knl.
Warning: Package xdc.runtime.knl is experimental in this release, and its interfaces can be expected to change in an incompatible way in upcoming releases.
A command line tool that creates a RTSC bundle containing all packages loaded in the process of configuring an application. The resulting bundle can be distributed and consumed without installing any additional products, including XDCtools itself.
The tool is available in package xdc.tools.closure. Documentation is available on the web here.
Warning: Package xdc.tools.closure is experimental in this release, and can be expected to change in an incompatible way in upcoming releases.
XDCtools bugs are filed at bugs.eclipse.org.

Warning:Starting with XDCtool 2.95, RTSC packages with target content are incompatible with target content from previous releases. Compatibility of meta only content is not affected. Packages with target content would require a recompile. Starting with XDCtool 3.00 release both backward and forward compatibility is maintained for all content.
The packages comprising the XDCtools release are uniquely identified by a compatibility key defined in the package.xdc file of a package. Please note that the package compatibility keys are independent of XDC product release numbers.
Package compatibility keys are intended to:
Package compatibility keys are composed of 4 comma-delimited numbers - M, S, R, P - where:
This release supports the following hosts:
This release requires the following other software components and tools versions to successfully function:
This release supports the following device families:
This release was built and validated against using the following components:
The following major issues are known to exist in this release.
XDCtools now correctly interprets the "imports" statement used in module .xdc files. Previously the import statement incorrectly imported all modules in the same package in addition to the one named. These extra modules are no longer imported, and content packages that incorrectly relied on this bug now correctly fail with an error message when used or built. This can affect users how unknowingly use content that has this issue.
The most common symptom is the error message "can't resolve name" when configuring an executable. The solution is to update the content that relies on the bug. The content producer should add import statements to the .xdc files for the missing modules.
Command-line operation on Linux is fully supported.
All releases have 4 digits (M.mm.pp.bb). This includes GA and pre-releases (engineering, EA, beta, etc.). Pre-releases are denoted with a suffix (e.g. 3.15.01.51-eng or 3.15.01.58-beta).
This product's version follows a version format, M.mm.pp.bb, where M is a single digit Major number, mm is 2 digit minor number, pp is a 2 digit patch number, and b is an unrestricted set of digits used as an incrementing build counter.
To support multiple side-by-side installations of the product, the product version is encoded in the top level directory, ex. xdctools_3_15_00_50.
Subsequent releases of patch upgrades will be identified by the patch number, ex. XDCtools 3.15.01.67 with directory xdctools_3_15_01_67. Typically, these patches only include critical bug fixes.
Please note that version numbers and compatibility keys are NOT the same. For an explanation of compatibility keys, please refer to the 'Upgrade and Compatibility Information' section.
