    What is your environment: for example Keil, Windows 10, etc? In general, "debug" and "release" modes are "build configurations" that is sets of flags and options for the compiler. Typically debug mode means add info to the binary so that the debugger can read it and tell you where the program is in terms of symbols from the source code. Release mode typically means that info is absent. Also, release mode might disable any assertions, and perform code optimization. If debug mode works, why do you want to use release mode?
