Hi
We are using ECOS for our application.
We have configured ECOS for ARM PID7t board.
We have a query :
1) How do we route some hardware interrupt (say timer) to the FIQ
vector of ARM using ECOS
We are able to attach a harware interrupt using the kernel APIs
cyg_interrupt_create / cyg_interrupt_attach but the interrupt gets
routed to IRQ. When we try to set the same interrupt for FIQ it doesn't
work.
It gives the following
Spurious Interrupts : vector : 0 data : 0
