In this article, we communicate our embedded cortex-m with the PC during debug session using a trick called semihosting. This trick provides access to host IO (console, filesystem, shell execution) remotely from our embedded device.
In the previous articles, you learned how to write initialization code and put it in the correct place in the processor memory. Now you will learn how to generate the proper binary for send to ROM and will see various tricks to simplify your live with gnu make and Makefile.
