CCS/LAUNCHXL-F28379D: Running LCD-Code on Flash or on RAM gives different Results on Screen

Tool/software: Code Composer Studio

Hey Guys,

i wrote my own driver for 2x16 LCD Screen, it's my first project in CCS and maybe also in C. I debugged it on RAM of CPU1 everything looked perfect at the LCD Screen, so i decided to make a run alone version out of it and so i wanted to flash it to the Flash memory of the CPU. Now i have 2 times instead of my data a random character which isn't in the standard library. But the rest looks to be the same. So it seems that the controller make different things when programm is running on Flash or RAM Memory. Do you have any idea why?

Hi Stefan,

After flashing the device, do you see issue in standalone mode execution only or even when debugger is connected ? If you see issue with debugger connected as well then you may have to step through the code to debug this.
