Shared buffer switch

Webb4 juni 2015 · The approach I took involves placing the data structure itself (or the “management” portion) into the start of the shared window, followed by a buffer that the data structure manages. This works just like an implementation of a stack or list that has all of its nodes allocated up front except here we also place everything in a set location … WebbMany thanks to berendi for the recommendation, which I followed. I wanted to share data between the 2 cores, CM4 and CM7, in an STM32H745, using the STM32CubeIDE to program a NUCLEO-H745ZI-Q board. First, I defined the following struct and pointer in main.c for each of the cores. I used the same names in main.c for both CM4 and CM7.
