Hello,
I've got a bit of a design question. Eventually I want
to service all types of interrupts i.e. Ethernet, DMA,
MII, UART, PCI etc.
The problem I have is that all of these interrupts latch
up to a bit in the "cause" register. Now the question
I have is should I change the "hal_interrupt_handler" to
call another handler to then check which actual
peripheral caused the interrupt which in turn calls the
devices ISR or should I go about it in a different way.
I don't really know the philosophy of eCos enough to
know what would be the best course of action?
Any advice?
Cheers,
Col.
