Unable to Communicate with FS2400 Using KITFS24SKTFDMEVM and NXP GUI

Subject: Unable to Communicate with FS2400 Using KITFS24SKTFDMEVM and NXP GUI

Hi,

I am trying to configure and program the OTP on the FS2400 using the KITFS24SKTFDMEVM evaluation board.

Evaluation board:
https://www.nxp.com/design/design-center/development-boards-and-designs/KITFS24SKTFDMEVM

However, when I connect the board to the NXP GUI, I am unable to establish communication with the device. The GUI reports the error shown below, and no communication takes place.

I have previously used the same NXP GUI with the FS26 evaluation board without any issues, so I believe my PC setup and GUI installation are working correctly.

The evaluation board is in its default configuration, and I have not intentionally changed any jumper or switch settings. To verify, the current configuration is as follows:

S12 (OTP): OFF
J30: Pins 1-2 connected
SW4 (WAKE2): ON
S19 (WAKE3): ON
J33: Open
J37: Pins 2-3 connected
J36: Pins 2-3 connected
J10: Pins 2-3 connected
SW9: All switches ON
J45: Pins 2-3 connected
J26: Pins 5-6 and 9-10 connected
SW20: All switches OFF
S2: ON (I could not locate this switch in the schematic )
SW18: All switches ON
SW1 (Main Power Switch): Position 3 (2-3)

I have not programmed the S32K144 MCU on the evaluation board. My understanding is that the board is shipped with the required firmware already programmed. Could someone confirm whether this is correct, or whether the MCU needs to be flashed before the GUI can communicate with the FS2400?

Below is the error message displayed by the GUI:

Any help would be greatly appreciated.

Thank you.

Hello,

Thank you for contacting us.

Could you please update the firmware according to Section 5, "Installing and Configuring Software and Tools," of the UM12015 KITFS24SKTFDMEVM User Manual? This procedure should resolve the error you are experiencing.

If the issue persists after completing the update, could you please provide a picture of your hardware setup? This will help us review the configuration and investigate the problem further.

Thanks!
