why taskpool lib malloc memeory using static and dynamic both?

[yourslab]

That is just the nature of the code - The taskpool requires memory to be allocated both statically and dynamically. However, the taskpool is being deprecated in our coming-soon LTS release by rewriting our libraries to not depend on it.

As for the linking error, could you please provide the error so we can help you debug? Perhaps, you must define both of these macros in FreeRTOSConfig.h:

#define configSUPPORT_DYNAMIC_ALLOCATION        1
#define configSUPPORT_STATIC_ALLOCATION         1

yes, it could be linked success, after i defined configSUPPORT_STATIC_ALLOCATION 1 at FreeRTOSConfig.h . i just confused that this is not follow the freertos memory management guidance. it seems that taskpool does not support dynamic memory managment.
BTW. if taskpool is being deprecated . will other library provide the same feature? thanks.

Other libraries will provide the same features, but tasks will be allocated by the application. This way, all memory management will be up to the user. If you need a mechanism for creating tasks in your application, I suggest taking a look here.
