Resolving The Problem. To enable floating point, set the environment variable ROSERT_TORNADO_OPTIONS to VX_FP_TASK. When this is set the application checks if the processor supports floating point, and if so, it runs the target with the floating point option.

Dec 29, 2014 · In VxWorks, each task that utilises floating point has to be specified as such in the task creation so that the FP registers are saved during context switches, but only when switching from tasks that use floating point. This allows non-floating point tasks to have faster context switch times.

This technote provides information on how IBM Rational Rose RealTime spawns VxWorks tasks (threads) using the Tornado VX_FP_TASK option. In the Target Run-Time Services (TargetRTS) library the RTThread constructor calls taskSpawn() and sets the options for the child task by doing a bitwise AND of the floating point coprocessor support bit with the options of the parent task.

And Stan Schneider says, You have to set the "VX_FP_TASK" option flag when you spawn your task. You also need to make sure you don't use the FPU in any interrupt service routines. Even if your code uses no floating point, some (brain-dead) compilers save some FPU registers at the start of all routines if there's any floating point in the file.
