I do have configENABLE_BACKWARD_COMPATIBILITY set to 1. However is it defined as 1 in FreeRTOS.h. This is my FreeRTOSConfig.h file:

I’m not 100% on all the settings, so if you see something wrong please point it out to me.
Also I was able to solve the multiple definitions issue. Port.c defined xPortSysTickHandler, xPortPendSVHandler, and vPortSVCHandler, but the prototypes for the functions weren’t in portable.h, which is what FreeRTOS.h includes, not port.c. In my CM3Start.h file, where the interrupt vector is, I originally included port.c but then it didn’t see the prototype of the pxPortInitialiseStack function because of the include order. So I added the prototypes for the interupt functions in to portable.h and included FreeRTOS.h in the CM3Start.h file. This solved the issue where it said the interrupt functions were undefined, and the issue where there were multiple definitions of pxPortInitialiseStack. So that’s all good (I think).
However, now I’m back to square 1 . It’s doing the same thing in the first post, where it ends up in CY_ISR(IntDefaultHandler) after executing the prvPortStartFirstTask function. I would expect the interrupts to be set correctly since I added those functions in the vector table. I think I need to do something else to get the interrupts set properly. I’m not sure what.
Also this is my make file. I did copy files over from the demo application to a separate project after making. Maybe I missed something? I’m not completely sure what the make file is doing to set the interrupts, so that could be what I missed.
