Hi,

I am getting compilation error, when i try to compile FreeRtos with Rowley’s Crossworks for STM32F207IG.  
I am using version 6.1.0 of freeRtos. I am getting a compilation error in the File “queue.c” & port.c  
The error are “undefined reference to vPortSetInterruptMask”

Building “Example” in configuration “THUMB Debug”  
&nbsp; Compiling queue.c

Kindly Oblige

Where did the project come from?&nbsp; I’m using FreeRTOS V7.3.0 and there isn’t a vPortSetInterruptMask() function or macro in the CM3 GCC port layer.

I just tried compiling the FreeRTOS\Demo\CORTEX\_STM32F107\_GCC\_Rowley demo and didn’t get any problems (there were 17 warnings that came from the uIP stack code, but it compiled and linked).

Regards.

Thanks for the reply, I am using freeRtos V6.1. I have used the source file from other FreeRTOS project Build on Different IDE.  
The Project is based on demonstration of building on top of the LwIP (Lightweight IP) TCP/IP stack.

I have also tried & compilied&nbsp; FreeRTOS\Demo\CORTEX\_STM32F107\_GCC\_Rowley demo without any errors, but i cannot use this, as I am using STM32F207IG based Development board.

Kindly oblige.

All the Cortex-M3 demos use exactly the same port layer code.&nbsp; FreeRTOS does not care if it is a 107 or a 207, but you will have to change the linker script to have the correct memory layout.
