Hi,
When I am trying to detect my target platform having ARM v7 processor using the ARM DS -5 Debugger . I am getting prints like this

Can anybody resolve this issue?

I have no experience with ARM DS-5, but may be information by reference helps you to understand
https://developer.arm.com/docs/dui0498/i/creating-debug-hardware-target-configurations/about-configuring-a-device-list
IR - Instruction Register and DR - Data Register are parts of JTAG test access port, these registers give you a way to access ARM debug port on target.
IDCODE - device identification number
