problem compiling example application in Compilers and IDEs Posted July 29, 2014 I hope you are compiling the application from "StellarisWare\boards\ek-lm4f120xl\blinky" directory. No, I have a Tiva launchpad; on the box it says "TM4C123G" and "EK-TM4C123GXL". I am therefore compiling in "examples/boards/ek-tm4c123gxl/qs-rgb/". I believe that flashing works correctly, because all applications that I have tested work as expected when I flash the binary initially provided in the package. Only when I compile by myself does the application not work. There is a line, CFLAGSgcc=-DTARGET_IS_BLIZZARD_RA2 -DUART_BUFFERED Try commenting that line. When I do that, I get plenty of compilation errors of undefined references to 'ROM_*' functions. I am using the current version (4.9.1-1) of arm-none-eabi-gcc of the Archlinux distribution, and have also installed the arm-none-eabi-binutils (2.24-1).
