12.1 EDK - When I use the FPU in a PPC design, there seem to be random interrupts

描述

When I use the FPU in a PPC design, there seem to be random interrupts. Is there a solution?

解决方案

To work around the problem, use a dummy exception handler:

#include "xexception_l.h"
:
:
main()
{
XExc_Init()
:

Using the XExc_Init function will call in a "do nothing" handler for every exception.

This problem affects all versions of the core.
