main() is not a root with gcc, start() is (defined by your linker script), and is usually provided by crt0.o - except you told it not to with -nodefaultlibs.
The flag you really want is -minrt, which tells gcc to encode extra information in each object that helps the linker reduce the amount of runtime needed to only the routines that will actually do something useful (and, most likely, remove C++ constructors/destructors at the same time). If even with that flag the code still doesn't fit, add -Wl,-Map,somemap.txt and see *what* functions are getting included, and why. It may turn out to be something silly. Also, if main() returns a value, the runtime may include extra processing to happen at exit() time, which is kinda pointless on an MCU. main() should end in a while(1); so it doesn't return. ------------------------------------------------------------------------------ Meet PCI DSS 3.0 Compliance Requirements with EventLog Analyzer Achieve PCI DSS 3.0 Compliant Status with Out-of-the-box PCI DSS Reports Are you Audit-Ready for PCI DSS 3.0 Compliance?
