ChibiOS Free Embedded RTOS

Hello folks,

I have started playing with latest version (18.2.1), and the built binary for F412ZG demo is around 300kB. When I was using CubeMX and freertos demo for usb, the code size was 30kB. What are some of the things you suggest me to look at in the config/build process. I am a relative newbie so any insights would help! Thanks.

Usually the test harness is included in the build, which generates a printout to some serial port triggered by a button on the hardware.

Look in the loop at the end of main() to see this; remove the call, and maybe remove from makefile

Correct, you need to remove the test code from the demo and make sure to compile using -O2, some demos are defaulted to -O0 (no optimizations).
