suppress incompatible pointer types in Azure RTOS demo program

New Contributor

I am bringing up Azure RTOS on a new ARM M4 platform.

Most everything is built and running. I patterned the port closely after the Microchip ATSAME54-XPRO ARM M4 getting stated platform.

I removed the Azure IoT main.c and replaced it with the simple demo test program as described on   Chapter 6 - Demonstration System for Azure RTOS ThreadX | Microsoft Docs

 

When I compile I am getting this warning/error that do not know how to suppress:

Can some one help?

I was able to get it to compile by adding a cast in front of the &pointer ((void **)&pointer) but don't think that's the best way to handle.
