Where did you get the port from? I don’t think it is a supported port.
From the error message it sounds like the addressing mode used to access vTaskSwitchContext() from assembly code (if it was done from C code the compiler linker would fix it automatically) cannot do so because vTaskSwitchContext() is too far away in the address range. You could try placing the code in a known section so call related code is close together, or changing the addressing method. These are just guesses though.
thanks…yes it is an unsupported port but im trying to make it work….now im placing all the call related code in ‘text’ section and it worked…i mean the errors are gone but now the freeRTOS is not switching tasks….i have created 3 dummy tasks and freeRTOS runs only the last task created (if all are at the same priority) and in case of different priority only the highest priority task…
