Struggles with X-Cube-AI and printf(LC_print)

LukasOst

Hello everyone,

I am currently experimenting with X-Cube-AI with a NUCLEO-G474 (because i get some weird errors with NUCLEO-N6 [N6 Post] ). I am trying to run a very simple network with the validation application. I have some Questions which i have not been able to answer myself regarding X-Cube-AI.
I first tried to print something to my pc console. I used UART with the function HAL_UART_transmit. This works fine.

Then i want to do the same with the X-CUBE-AI package in use. The first thing i see is that syscalls.c is removed from the core folder and moved into X-Cube-AI/app. In  app_x-cube-ai.c in MX_X_CUBE_AI_Process() ->aiValidationProcess() i found the function LC_PRINT which also uses HAL_UART_transmit. But i cant see nothing in my terminal.

I am not sure what i did wrong. Can someone help with this problem?
