Hi Eshan, We can work with the newlib community. Some things can be done in newlib that are only for RTEMS, while some things we should share with others, and still more code may be not useable by RTEMS (e.g., what is in sys/linux). It is best to try to make common code available, but if some code has to be specialized for RTEMS differently than how it works in other systems then we can do that.
