Issue with Simulink and Arduino Nano 33 IoT

I am writing to bring to your attention an issue I encountered while working with Simulink and Arduino Nano 33 IoT.

I have 8 AEK rev.2 boards, and as a teacher, I began working with one of them. While everything appears to be in order, I am facing difficulties running models on the board in Simulink IO mode. Specifically, the example provided at [ https://www.mathworks.com/help/sldrt/ug/sync-models-by-using-arduino-connected-io-board-example.html#d126e10613 works on my UNO but encounters an error on Nano 33 IoT. The error from Simulink is as follows:

Error: MATLAB System block 'sldrtex_arduino/Digital Output' error occurred when invoking 'setupImpl' method of 'codertarget.arduinobase.blocks.DigitalWrite'. The error was thrown from 'C:\ProgramData\MATLAB\SupportPackages\R2023b\toolbox\target\shared\devicedrivers\+matlabshared\+devicedrivers\+blocks\DigitalIO.p' at line 0 ... Caused by: Configuring Pin 13 as Digital Input/Output failed. Pin 13 is not a valid Digital Input/Output pin. Reconnect the hardware, provide a valid Digital Input/Output pin number for your hardware and try again. However, deploying and Start code for DC motors, servos, or Lion Battery monitoring has been successful. Additionally, the Monitor and Tune Simulink mode works well on Nano 33 IoT.

I would appreciate any recommendations on how to set up Matlab/Simulink to address this issue.

Thank you for your assistance.

https://itp.nyu.edu/physcomp/introduction-to-the-nano-33-iot/ says that Pin 13 is Reset

You might possibly be having difficulty because of the difference between the physical pin numbers (such as 13) compared to Digital Pin numbers such as D13

According to https://static.rapidonline.com/pdf/73-4863_v1.pdf D13 is physical pin #1

But whent i deployed it and run , everything is ok .

Here is the solution which works for me: https://forum.arduino.cc/t/simulink-communication-interface-missing-serial/1069853/10?u=radko_kozakovic There is necessary to correctly set up Different numbers for host com port and for Bootloader COM port.
