Hello,
I an using this architecture for an application and since FPU exceptions are not trapped (according to errata), my platform running the applications performs FPU check at each cycle to see if any FPU errors occurred.
Yet, we need to be sure the application cannot erase the FPU flags, and the FPSCR register seem accessible anytime. Is there any way to disable the VMSR instruction before launching my application ? Or better, another way to trap FPU exceptions ?
Thanks
Regards
