Subject: [ECOS] LPC2XXX watchdog feeds and interrupts
Date: Mon, 26 Oct 2009 09:58:00 -0000 [thread overview]
Message-ID: <005101ca5622$d9bf4c30$8d3de490$@gellatly@netic.com> (raw)
In-Reply-To: <20091025132007.GA4436@sg-laptop>
Hi All,
I using an ARM 7 (LPC2212) based on an eCosCentric build. It appears that
watchdog feeds are done with interrupts enabled yet the NXP manual
warns against leaving interrupts enabled during a feed sequence (and I'm
pretty sure I've seen the consequences).
Firstly, have I missed something? Are interrupts disabled and I just don't
see where when I call watchdog_reset()
OR
should I be adding cyg_interrupt_disable() and cyg_interrupt_enable() calls
around the feed sequence in watchdog_lpc2xxx.cxx
Thanks ...Laurie:{)
