Cortex-A55(ARMv8.2-A) source code debugging method

Hello Folks,

I want to debug the Cortex-A55 (ARMv8.2-A) source code using Arm DS-5 v5.29.3.
The build has completed successfully, and when debugging is specified with arm-none-eabi-gdb.exe in the debug configuration, the following error message is displayed and debugging cannot be started. What could be the cause?
The debug configuration is using C/C++ Remote Application.
The compiler I am using is ARM Compiler 6
I get a similar error on ARM DS 2022.2.
Cortex-M3 (ARMv7) can be source code debugged by the above method.

Or is it a makefile setting error?

The build environment uses the following, and the makefile is not edited.
