Please try opening FreeRTOS.h, and finding the lines: ``` #ifndef configUSE_PORT_OPTIMISED_TASK_SELECTION #define configUSE_PORT_OPTIMISED_TASK_SELECTION 1 #endif ``` and change the 1 to a 0. That fixes the problem for me. The default of one will have to move into individual port layers. Regards. ---
