User can specify which binaries he needs on the commandline. 'make hex' will build examples with generating hex file 'make hex bin' will build hex and bin output 'make images' will build all images as in previous versions of buildsystem 'make all' or 'make' will build only elf (+ map) files This will have huge impact on build speed.
------------------------------------------------------------------------------ README ------------------------------------------------------------------------------ This repository contains assorted example projects for libopencm3. The libopencm3 project aims to create an open-source firmware library for various ARM Cortex-M3 microcontrollers. For more information visit http://libopencm3.org The examples are meant as starting points for different subsystems on multitude of platforms. Feel free to add new examples and send them to us either via the mailinglist or preferably via a github pull request. Usage ----- The makefiles are generally useable for your own projects with only minimal changes for the libopencm3 install path (See Installation) For flashing the 'miniblink' example (after you built libopencm3 and the examples by typing 'make' at the top-level directory) onto the Olimex STM32-H103 eval board (ST STM32F1 series microcontroller), you can execute: $ cd examples/stm32/f1/stm32-h103/miniblink $ make flash The Makefiles of the examples are configured to use a certain OpenOCD flash programmer, you might need to change some of the variables in the Makefile if you use a different one. You can also flash manually like this: $ openocd -f interface/jtagkey-tiny.cfg -f target/stm32f1x.cfg $ telnet localhost 4444 > reset halt > flash write_image erase foobar.hex > reset Replace the "jtagkey-tiny.cfg" with whatever JTAG device you are using, and/or replace "stm32f1x.cfg" with your respective config file. Replace "foobar.hex" with the file name of the image you want to flash.
