TASKING VX-toolset for TriCore v6.2r2 patch 5
Release Note
Scope
This release note covers the changes between v6.2r2 and v6.2r2 patch 5 of the TASKING VX-toolset for TriCore.
For release notes prior to v6.2r2, please visit the TASKING
TriCore support website.
Contents
This patch contains changes to the following components:
-
TriCore C++ compiler
-
TriCore C compiler
-
TriCore assembler
-
TriCore control program (for C++ compiler invocations)
-
The stdbool.h header file (when used in C++ code)
-
TriCore libc++ header files
-
TriCore STLport C++ header files
-
SFR files for AURIX 2G
Please note that the TriCore libraries have been rebuilt.
These libraries are also part of this patch.
From release v6.2r2 patch 4 onwards the following components are present:
-
Files to provide compiler support for TC35x, TC36x and TC37x AURIX devices
Note that when you change the device of an existing example to one of the newly supported devices,
the start up files and sync_on_halt must be re-imported. For the tc_blink_aurix example this is not required.
-
Files to provide debugger support for the following AURIX hardware:
- TC357 on a TC3x7 TriBoard
- TC377 on a TC3x7 TriBoard
Note that a DAS driver version higher than v7.0.6 is required to support the TC377 device.
- TC387 on a TC3x7 TriBoard
Please note that this patch does not add Pin Mapper support
for TC35x, TC36x and TC37x. Support for these devices is provided
by means of the stand-alone version of the Pin Mapper.
For this patch, the following executable files have an updated build number: Build 20090177.
- ctc\bin\astc.exe
- ctc\bin\cctc.exe
- ctc\bin\cptc.exe
- ctc\bin\ctc.exe
All other executable files still have the original v6.2r2 build number: Build 18041957.
