CORTEX STM32F107 GCC Eclipse Demo

Posted by *anonymous on November 5, 2011


I am attempting to port the current GCC Rowley Demo for the STM32F107 to Eclipse/OpenOCD. I am using CodeSourcery (Lite) for the cross compilation tools. I seem to having trouble building the project though.

When compiling the file stm32f10x_nvic.c the following error comes up:

FreeRTOS/Demo/CORTEX_STM32F107_GCC_Ecplise/../Common/drivers/ST/STM32F10xFWLib/src/stm32f10x_nvic.c:190: undefined reference to `__SETPRIMASK'

Several of these errors are displayed (with different undefined references) for this file. I have traced '__SETPRIMASK' to Demo/Common/drivers/ST/STM32F10xFWLib/inc/cortexm3_macro.h, which is included via stm32f10x_nvic.h.

So I don't see why these errors come up, I imagine it is because of a missing include directory or missing pre processor directive, but I can't see what is missing, anybody else come across this problem/have any ideas?

Here is my makefile for information:

# Makefile for use on the STM32-P107 Olimex board

# Project directories
# RTOS_SOURCE_DIR -> RTOS source directory
# DEMO_COMMON_INCLUDE_DIR -> Common demo header files
# DEMO_COMMON_SOURCE_DIR -> Common demo source files
# DEMO_DRIVER_DIR -> Common demo driver files
# UIP_COMMON_DIR -> Networking files
# STM32F10X_SOURCE_DIR -> Microcontroller specific drivers

# Demo additional files, ignore for the moment
# target file?

I have published some FreeRTOS demo running on Eclipse/GCC (Code Sourcery) at the following link: http://www.stf12.org/developers/Download.html.
Look for Cortex_STM32F107 demo.

Thanks for the demo. I managed to get the project building and downloading onto the board.

I seem to be having a problem creating tasks now though, I create a task to turn some LED's on, however it never seems to get run. There are no other tasks being created.

Here is the call to the task creation function:

xTaskCreate( vLEDEnableTask, ( signed char * ) "LEDx", 128, NULL, 2, ( xTaskHandle * ) NULL );

Has anyone come across this problem before?

Cheers, Michael

Have you checked the xTaskCreate() return value?

Yes it returns pdPass.

Cheers for the quick reply.
