FRDM USBDM debugging failure

Dears,

I'm using USBDM SW 4.12.1.230 and driver 4.12.3, both of them were latest downloaded from official sourceforge site.

A quite weird problem: I programmed my FRDM-KEAZ128Q80 with FRDM-KEAZ128Q80_Unique_ID.sx to support USBDM-on-FRDM to debug external MCU KEAZN8AMFK. The standalone ARM programmer application works well, my application can be programmed successfully and run OK, but failure occurs when debugging using CodeWarrior 10.7, error message dialogue shows:

Failed to resume target process.
ARM GDI Protocol Adapter : An error occurred while trying to write memory. ARM transaction Fault

Consol prints:

It seems USBDM driver attemps to write memory but failed?

PS: FRDM-KEAZ128Q80 was modified to 3.3V-compliant and works well for debugging my another product which using KEAZ128. The connection between FRDM and target board is 3-wire: SWD_DIO, SWD_CLK and GND, target board is 3.3V powered.

Thanks in advance for any hints.
