Autodetection failure when trying to debug a bare metal platform with ARM development studio and dstream

I have an ARM cortex-A9 based bare metal platform that I am trying to debug with dstream and evaluation version of ARM development studio (installed on a windows 64 bit machine)

I tried adding/detecting the platform via auto detection (File->New->hardware connection)

The logs from auto detection (in console tab of ARM DS) are as shown below,

The measured device IR lengths do not match the total scanchain length.
An attempt will be made to correctly identify scanchain devices, but in the case of failure,
the scanchain should be configured manually.

The following scanchain will be used:
[10/04/19 16:06:46] JTAGDeviceInfo[IDCODE = 0x5B16017F, IR Length = 16, Name = UNKNOWN_16]

On a working box, my FreeBSD boot up shows the below attributes for the chipset

-------------------------------------------------------------------------------------------------------------

CPU: ARM Cortex-A9 r4p1 (ECO: 0x00000000)

CPU Features:

  Multiprocessing, Thumb2, Security, VMSAv7, Coherent Walk

Is there any guidance/advise on what should be done further to get the dstream to detect the bare metal platform and be able to debug it?

fyi...The dstream is connected to the target platform via a JTAG connector, the ARM DS is connected to the dstream via the USB port.
