I suspect you are using the Classic API (e.g. rtems_task_) and by default they do not have floating point enabled. You probably just need to enable the floating point attribute on the task create calls (or for the init task). https://docs.rtems.org/branches/master/c-user/task/directives.html#rtems-task-create See configuring a system chapter for the init task setting. If you provide the exception, we would know for sure. --joel > > Thanks! > > [image: Astrobotic Logo] *Dave DeGroote* > > Flight Software Engineer > > *Astrobotic* > > 1016 N.
