CCS/TM4C123GH6PM: unable to display message on LCD 16x2.

Part Number:TM4C123GH6PM

Tool/software: Code Composer Studio

Hi 

I am using JHD 162A LCD module to display a message("Hello world").

I am able to build code without errors but when I tried to run it, the program stucked into exit.c file.

And the LCD is displaying:

1st row - 16 "5X7" matrix

2nd row - blank.

// PB0-7 -> Data lines D0-D7
// PD0 -> RS
// PD1 -> Enable

I have compiled this code from various posts from this community.
