TDA4VM: Performance of MCU UART log is bad.

Part Number: TDA4VM

Hi , experts.

I use vision_apps on TDA4VM at following environment.

MCU1_0:RTOS (my app)
MPU1_0:Linux (vision_apps)

I want to use MCU UART log for debug , but I have one problem.

MCU UART log output too slow.

When UART_printf() called once , it took 30~35ms.

Is it limitation of perfomance? Can I improve it?

If possible , please tell me how to modify it.
