Mbedtls ECDSA on micrium RTOS in threaded environment

Hi,

I am trying to implement ECDSA sign and verify algorithm using mbedtls.

IDE using : Simplicity Studio
Target board : BGM13P32 Blue Gecko Module Radio Board (BRD4306B)

There are example projects in simplicity studio which implement mbedtls ecdsa in a single threaded application. But I want to implement this in threaded environment using micrium RTOS.

I have referred below link but still I am getting below error.
Any help is really appreciated.

Mbedtls on RTOS
