Hello Tonny,
the report containing all system parameter is printed within the function EwPrintSystemInfo() that you will find within the file ewmain.c.
You can enhance this function in order to add your own system information, e.g. the configuration of the serial interface (UART).
For printing the report (or any other message), the function DbgConsole_Putchar() is used. This is part of the NXP SDK. The serial interface is initialized within the NXP SDK - please have a look to the corresponding files (\ThirdParty\MCUXpressoSDK\components\serial_manager).
Is this what you are looking for?
Best regards,
Manfred.
