[Xenomai-core] use case: possible to boot Posix subsystem in <50ms and then Linux?

2009-03-27 Thread Peter Wächtler
Hi Xenomai developers, for automotive control units the boot time is essential. After power-up the first status message has to be sent in about 50ms. This is usually achieved by a RTOS with boot times far below. Is it possible to construct a system with Xenomai that boots the POSIX (or whateve
