Stuck on _exit() in syscalls.c with void STM32TouchController::init() - STM32F469I-DISCO

[Kneepatch]

I can't get my display to work after I enabled the uSD card on my STM32F469I-DISCO, it just sits at a black screen. When I ran the debugger, this is the call stack it shows, stuck on _exit() in syscalls.c:

Is there an easy way to determine what conflict is happening when I add my uSD card? Full disclosure: using TouchGFX to generate this project file in STM32CubeIDE.

I've got exactly the same issue this afternoon.

CubeMX Ver 6.13.0

TouchGFX Ver 4.24.1

Running on STM32H747I-Disco with different screen. Instead of the 800x480 screen that comes with the dev kit, I've got a 5" 720x1280px display. The TouchGFX & STM32CubeIDE projects were built from the blank discovery kit project in TouchGFX designer and then modified in CubeMX to meet the correct specs for the screen.

So it looks that BSP_TS_Init() returned not TS_OK. Debugger is your friend.
