[ECOS] FIQ on ARM
Mon May 14 08:35:00 GMT 2001
I'm working on a stack from the 26th Feb, 2001, (it's been ported
to an internal board), I've noticed that my HAL routines such as
hal_IRQ_handler and friends don't investigate FIQ registers which I would
have to add, in another project we've used our own code on a separate FIQ
fine, but for this I need to get the eCos serial code to run from the
I'm hearing now from my group that I might be able to get away with
DSR'ing the long running interrupt and then using a soft FIFO between ISR
and DSR for the serial (v. small FIFO)... my long running interrupt is
fairly long... and run everyone from IRQ land ..
Thanks for your help,
