Hi,
I have questions about AM437x Interrupt.
1.
In AM437x datasheet(sprs851) page.3, there are following information:
////////////////////////////////////////////////////////////////////////////////
Up to Three External DMA Event Inputs That Can Also be Used as Interrupt Inputs
////////////////////////////////////////////////////////////////////////////////
But in page.83 "4.3.12 Miscellaneous", it seem that there are
9 External DMA Event or Interrupt Inputs.
Which is true?
2.
Does AM437x support FIQ interrupt?
I'm asking this question because it was unsupported in AM335x.
3.
Is only two interrupt lines(FIQ and IRQ) connected to Cortex-A9?
4.
AM437x supports 224 shared peripheral interrupts(SPI).
I guess that user need to assign SPI to FIQ or IRQ.
There are no information in AM437x Technical Reference Manual.
Is there any information?
best regards,
g.f.
