Hello Pavel, if you would like to reduce the memory footprint, then you can try out piclolibc as mentioned. You can also try using thread-local storage for the libc thread-specific data through the _REENT_THREAD_LOCAL option. Another option is to change the struct reent initialization for the _REENT_SMALL initialization to dynamically check if the stdio file streams are NULL before they are used. If they are NULL, then they are initialized to use the global __sf[] objects. Kind regards, Sebastian -- embedded brains GmbH & Co.
