Hi
I tried to use the FIT (Fixed Interrupt Timer) on my PPC405GPr board, which
uses 0x1010 as its interrupt vector in a user space (vxworks-skin)
application.
<..>
RT_INTR FITnterrupt;
res = rt_intr_create(&FITnterrupt, 0, 0x1010, I_NOAUTOENA);
<..>
But I got -22 EINVAL as error.
Could somebody please tell me, what is wrong with my example.
The 0x1010 is the HW interrupt vector, but the argument should be the
interrupt _line_. Besides, last time I checked, the ppc405 FIT isn't
even 'wired' in the kernel; actually, there's no space for the interrupt
prologue code, which basically results that no handler is called when
the FIT interrupt occurs.
