Hi @shivangi_23 

Could you please tell me the programs you are uploading to the board? Also, have you tried using another computer? Sometimes there are issues between versions of MCUXpresso and windows, could you provide me the versions too please.

I'll be waiting for your response,

Best Regards, Miguel.
