We would appreciate if you could read the following and give us some advice.

Operating environment
IDE: MCUXpresso IDE v11.1.0
SDK: SDK_2.x_MK64FN1Moxxx12
device: Rapid IoT
              Hexiwer Docking Station
Use Debug function from MCUXpresso IDE,
Write the sample project "frdmk64f_power_mode_switch" for frdmk64f to Rapid IoT.
* This Rapid IoT has been confirmed to work with the rapid iot k64f sample project "rapid iot_k64f_hello_world"
・ Starts up, but stops with the LED on the KW41Z side lit. The LED on the MK64F side does not light.
-It is possible to reset the power supply of the device, but the functions for returning to the factory default do not work.
-Even if the device and the PC are connected by USB, it is not recognized as a drive and cannot be written in binary.
・ Even if you write a Rapid IoT project with the debug function
Main processing does not start. (Is it skipped to an abnormal memory address?)
If the project was written by mistake, Main processing will start.

I also tried the following, but I could not solve it, so I would like to ask for advice.

In the procedure in the community (, the boot loader was rewritten with reference to the procedure described in the User's Guide (
However, it could not be completed due to a compilation error.

1: Download Rapid IoT SDK ( from NXP official HP
2: Import the kboot folder on the MK64F12 side from the unzipped SDK to the IDE as projects
3: When executing Build, the following compile error occurs

Do you have any solution or advice?
