title: Cannot find entry symbol _start
body: <p>My c code on compiling on gcc is giving the error <code>Cannot find entry symbol _start defaulting to 00000</code>. Can anyone tell me why and how to correct it?</p>
  
  <p>The command line is <code>arm-none-eabi-gcc -O3 -march=armv7-a -mtune=cortex-a8 -mfpu=neon -ftree-vectorize -mfloat-abi=softfp file path</code> and the target platform is a-8 sitara cortex processor.</p>
