| This is a generic Linux problem, not a LITMUS^RT^ problem. The configuration is missing support for your root device and/or your root file system. To boot LITMUS^RT^ on your machine, you first need to have working configuration for an unmodified Linux kernel. Once you have mainline Linux working your machine, LITMUS^RT^ should boot without problems as well. ---- |

FAQ
I would like to write a real-time application that uses the LITMUSRT API. Where should I start?
Have a look at the task bin/base_task.c in the liblitmus repository. It's a documented task skeleton that shows how to implement a periodic or sporadic real-time task.
Can I use pthreads with LITMUSRT?
Yes. An example for a multithreaded real-time application is provided in bin/base_mt_task.c in the liblitmus repository.
