I was trying to execute but getting error as Description    Resource    Path    Location    Type

Hi Sarin cr,

Thank you for your interest in NXP Semiconductor products and
for the opportunity to serve you.
To provide the fastest possible support, I'd hihgly recommend you to refer to the LPCOpen library of LPC11xx series.

Have a great day,
