I just downloaded the last version of FreeRTOS (RTOSV6.0.2) and IAR version 5.41 Kickstart.
Tried to open the project rtosdemo.eww located in …/Demo/uIP_Demo_IAR_ARM7, but I always get the error message : "The project ‘rtosdemo’ contains the unknown tool ‘STLINK_ID’. I also tried load other projects, but get the same error.
Did you open the project in an older version of IAR first? If so, please grab a clean FreeRTOS installation and try again. I just did this and the project opened and compiled with no problems.
The project was first opened with version 5.10 of IAR. After reinstallation of the FreeRTOS files I still got an error: “Broken option were detected in the project file” and after that I got the old error "The project ‘rtosdemo’ contains the unknown tool ‘STLINK_ID’.
It seems to be some mismatch beetween my versions of IAR and FreeRTOS.
The project was created using V5.40 and as far as I can tell opens and compiles without issues in V5.41. IAR will silently destroy a project if you try opening the project in a version of IAR that is older than the one used to create the project.
