Dear all,
I using the STM3210E-EVAL board which is based on the ST microelectronics STM32f103 uController.
I’m trying to use FreeRTOSV5.1.1 with IAR embedded workbench 5.20.
Based on the Demo project, i tried to use xSemaphoreCreateCounting() function but got the following
Linking Error:
Error[Li005]: no definition for "xQueueCreateCountingSemaphore" [referenced from F:\OS_Projects
\_FreeRTOS\FreeRTOSV5.1.1\FreeRTOS\Demo\
After digging a bit i found the following:
1. Inside semphr.h - there is this line
#define xSemaphoreCreateCounting( uxMaxCount, uxInitialCount )
xQueueCreateCountingSemaphore( uxMaxCount, uxInitialCount )
it seems that xSemaphoreCreateCounting( uxMaxCount, uxInitialCount ) does not have any
implementation at all.
Is this the reason i got the linking error which i mentioned above?
If not, can some let me know what would be the problem?
2. Does anyone know used xSemaphoreCreateCounting() function? if so, i would be happy to know
how?
Thanks in advanced
Beja.
