Trouble with X-CUBE-ST67W61M1 with X-NUCLEO-U545RE-Q

I am trying to use X-CUBE-ST67W61M1 but I am failing to read any data with COM port set as document um3449 indicates (I am currently using a UART-TTL converter connected on CN7 of X-NUCLEO-ST67W61M1). I am trying to update the X-NUCLEO-ST67W61M1 firmware to see if anything changes, but NCP_update_mission_profile.bat from X-CUBE-ST67W61 does not support update with my Nucleo board. Are there any ways to bypass this problem?
Moreover, any ideas about why I am not reading anything sensible from the X-NUCLEO-ST67W61M1 UART port? 
Thanks in advance for any advice

    Hello @jacob_ ,

    Have you verified the UART settings (baud rate, parity, stop bits) and ensured they match the configuration specified in the UM3449?

    Serial port setting: Select COM port number, 921600 baud rate, 8-bit data, parity none, one stop bit, and
    No flow control.

    Hello @Imen.D,
    Thank you for your answe first of all. The settings on my terminal are correct. In addition to this, I am not receiving anything from X-NUCLEO-ST67W61M1 when using examples of X-CUBE-ST67W61M1 (the chip does not seem to be enabled). Is UART port on CN7 still enabled for meaningful log when the board is in MISSION MODE?
