How to properly initialize shared arrays on STM32745? In my application I am using initialized data in shared memory for the use in a user interface. The memory is in the SRAM2 at 0x30020000. Both cores need to access that data, so I use code of the following form:__attribute__((section(".sram2"))) uiSelDef uiSelItem[4] = {
[0] = {"abc", 0.0f, 50, CENTER_CENTER},
[1] = {"def", 0.0f, 100, CENTER_CENTER},
[2] = {"ghi", 0.0f, 200, CENTER_CENTER},
[3] = {"jkl", 0.0f, 500, CENTER_CENTER},
}This code is placed in the Common directory so that it is picked up during compile time for both CM4 and for CM7 individually. Note that the initialization is not static on purpose.Why am I doing this? Roughly speaking, CM7 reacts on user inputs via interrupts (using encoders and switches) and shows updates on a screen based on user selection referring data from the array shown above. The CM7 then requests CM4 via semaphores to react to the user input. The CM4 access that very same array.So far so good. This works very well when I am in debug mode. Howev
