If it is the .axf/.elf file, then this has much more information in it than the code itself (means includes debug information).</P><P>If it is the .bin (binary), then it depends on the memory map as the .bin is basically a memory dump.</P><P></P><P>In any case: have you turned on optimizations in the compiler settings (e.g. -O3)?</P><P>The other thought is that code size heavily depends on how you are using the standard library (newlib? newlib-nano?, redlib?) and if you are using things like printf().</P><P></P><P>I hope this helps,</P><P>Erich</P></BODY></HTML> Fri, 06 Jul 2018 11:16:21 GMT https://community.nxp.com/t5/LPC-Microcontrollers/Why-MCUXpresso-binary-code-is-so-big/m-p/787451#M31668 BlackNight 2018-07-06T11:16:21Z
