Linux/AM5728: Missing remoteproc state file

Part Number:AM5728

Tool/software: Linux

I am using remoteproc to load DSP1 firmware from ARM.
I am able to load the DSP firmware however, I am not able to see the state file which is usually present here /sys/kernel/debug/remoteproc/remoteproc2/state

I need the state file to periodically check if the DSP1 is in running state.

How do I get the state file ?
