Sorry, this is not a good explanation. You force a GPIO to drop a feture, instead of disabling the feature itself. And maybe some other people want to have this feature enabled. Which is the timeout for the watchdog ? Why is it hitting too soon ? Fix should be not done simply removing the effect, but checking the cause. > > Signed-off-by: Giuseppe Pagano <giuseppe.pag...@seco.com> > Cc: sba...@denx.de > > --- > > diff -uNr a/board/udoo/udoo.c b/board/udoo/udoo.c > --- a/board/udoo/udoo.c 2013-11-06 18:47:26.000000000 +0100 > +++ b/board/udoo/udoo.c 2013-11-06 18:54:46.000000000 +0100 > @@ -168,6 +168,7 @@ > imx_iomux_v3_setup_multiple_pads(wdog_pads, > ARRAY_SIZE(wdog_pads)); > gpio_direction_output(WDT_TRG, 0); > gpio_direction_output(WDT_EN, 1); > + gpio_direction_input(WDT_TRG); I do not think this a right way to disable a watchdog.
