Known Issues with the Current Release
Coldfire V2 CodeWarrior port
The Coldfire V2 CodeWarrior code will not run with the latest (Eclipse) based
CodeWarrior tools. A fix is posted on the support forum
(post 4), and will be incorporated into the main release in due course.
Coldfire V1 CodeWarrior port
The Coldfire V1 CodeWarrior projects will not automatically update to later CodeWarrior
versions unless all unnecessary files are deleted from the FreeRTOS/Source directory first.
support thread for more information.
MSP430 CrossWorks and GCC demos
The CrossWorks demo has not yet been updated to use CrossWorks V2.0 or later.
The GCC demo has not yet been updated to use the latest MSPGCC compiler version.
The IAR Embedded Workbench demos for the AVR32 will not currently build if you are using a later version of the IAR tool chain. The issue is caused by
changes to macro names within the compiler header files.
Silicon Labs SDCC ports
Unfortunately these will not work with the latest compiler versions. The compiler version used to generate the port is now rather old, but is stated
on the port documentation page.
