My ARM DS version is 2019.1 Build: 201910913

    After contacting arm support.

    The CACHE_DEBUG_MODE option some how was not set. To check the option value, at ds command run

    $ debug-agent 

    look for CACHE_DEBUG_MODE option and it will show 0.

    set it to 1 and the I'm able to read the cache

    $set debug-agent CACHE_DEBUG_MODE 1

    interrupt the processor and read the cache.
