When i use UART at fp_vision_app.c,why i use usart1 (huart1)the led blue is shinning and the screen show all the information. But when i use usart2(huart2),the led blue is on and the screen get block(nochange) all the setting is the same only change all the 1 to 2.
sprintf(msg, "%s %.0f%%", NN_OUTPUT_CLASS_LIST[App_Context_Ptr->ranking[i]], *((float*)(App_Context_Ptr->Ai_ContextPtr->nn_output_buffer)+i) * 100);
HAL_UART_Transmit(&huart2,msg,10,1000);
