It will soft-reboot micropython after a burst of writes to the file system. This means that after you save files on your computer they will be automatically rerun. This can be disabled in the build by unsetting AUTORESET_TIMER in mpconfigboard.h. Using the REPL will also prevent the soft resets until you reset with CTRL-D manually.
