Hi Shivanand
I have already done a thorough investigation, this is what I concluded and found:
The RD-K358BMU already has the NBP8-9x internally (the NBP8FD4T1 is from this family), so it is not usual that it needs an extra drive, it should already have the necessary software to work correctly, maybe there is a configuration problem I recommend you follow the following link:

I recommend you download: Application Software for the Host MCU connected to the NBP8 – KE15Z FreeMASTER demo
But if you want to use an external sensor different from the internal one, download this: Application Software for the External MCU connected to the NBP9
I hope this information has helped you, please let me know if you need help with anything else.
Have a great day and best of luck.
