This is the first time for me to use an arm7 platform. I’m using the winidea IDE to develop and debug the software (it seems to be similar to Rowley) and I just port and compile the FreeRTOS software, but I have a problem during the debug  when the FreeRTOS call the #define portRESTORE\_CONTEXT. Is the someone that have just make the porting of FreeRTOS on the i system toolsouite? Can you help me? Thank you… ---
