Comment (by Sebastian Huber): Replying to [comment:1 Chris Johns]: > Will the changes include the examples and the `devfs` hello world example? Yes, the aim is to fix this example so that it works with Termios based console drivers. > > How doe the size of this approach compare to the `devfs` approach? I don't have numbers yet. I guess it will slightly increase. You can further reduce the code size if you disable the support for the legacy IO drivers and use the new IMFS_add_node() instead. I don't think this matters. If you want a minimal setup, then why do you want to use the POSIX open/read/write API to access devices? The POSIX functions pull in errno for example which pulls in the re-entrancy support which pulls in a hell of dependencies. -- Ticket URL: <http://devel.rtems.org/ticket/3894#comment:2> RTEMS Project <http://www.rtems.org/> RTEMS Project
