Aurix ShieldBuddy TC 375 Serial1 Do not Work

Hello Admin .
I am having trouble compiling a sketch code in Arduino IDE 1.8.19 with Hardware Aurix Shieldbuddy TC 375
Using Infineon User Manual , we are install it.
- The standard Arduino IDE installed from:  Arduino IDE 1.8.19
   free-entry-toolchain.hightec-rt.com/

-The Arduino development environment add-in for Eclipse and the standard Arduino IDE:
ShieldBuddy TC375 Multicore IDE ver 1.93
www.hitex.co.uk/fileadmin/uk-files/downloads/ShieldBuddy/ShieldBuddyTC375IDE.zip

All software above we are installed .
The serial channels are allocated as per:
SerialASC Arduino FDTI USB-COM micro USB
Serial1 RX1/TX1 Arduino J403 pins 17/16
Serial0 RX0/TX0 Arduino J403 pins 15/14
Serial RX/TX Arduino default J402 pins D0/D1


My trouble is Serial1 at Pin 17,16 do not work , can not read data from device has been connected.
In Arduino IDE Serial Monitor display blank ( do not display anything)
But in my Serial at pin D1,D0 and Serial0 at Pin 15,14 is read data from device normally ( not problem)
In Arduino IDE Serial Monitor will display normally data read from device.

This is my code :

}

}
