I don't think 20719 is supported in this forum yet. Please consult my China colleagues for clarification.
CYW20719 runs on ThreadX. Why do you want to use FreeRTOS? We provide RTOS APIs which you can use to create threads, queues, semaphores and mutexes.
My colleague is familiar with FreeRTOS, so they want run FreeRTOS in CYW20719. I will discuss with them.
