FREERTOS: How to enable osThreadIsSuspended ?

[ak52]

Hello Experts,

I see that in cmsis_oc.c that the function osThreadIsSuspended is disabled. The variable INCLUDE_eTaskGetState is responsible for it.

But how do we enable INCLUDE_eTaskGetState to 1 by default?

I see in FreeRTOS.h header than the macro is set to 0.

Can i just force it to 1 in FreeRTOS.h? or do we need to enable any particular config parameters in the .ioc file ?

Kindly Help!

You should define INCLUDE_eTaskGetState in project file FreeRTOSConfig.h

Note that cmsis_os.c is CMSIS RTOS V1 and it would be better to use cmsis_os2.c for CMSIS RTOS V2.

Thanks for your reply, I used CMSIS RTOS v1 as i am following along some FreeRTOS tutorials which also use the same v1.

I defined the macro in FreeRTOSConfig.h like this:

But, i get a bunch of errors related to the osThreadGetState function:

Any suggestions ?

it works for me.

osThreadSuspended is defined in cmsis_os.h if INCLUDE_eTaskGetState is set to 1

check that INCLUDE_eTaskGetState is really defined to 1 in cmsis_os.h

In cmsis_os.h,  I still see INCLUDE_eTaskGetState "grayed out", even though i have it defined in FreeRTOSConfig.h  :( , I am not sure why!
