[Gumstix-users] GPIO sleep mode and conections?

[<gs...@gm...>]

I have a Question I hope some one can help me with.

Is there any kind of automatic sleep mode on the GPIOs. I can't
comunicate using some of them after about 10 minuts of inactivity? I
have a devise conected to the gumstix, and am able to comunicate with
it for about 10 minutes then it just dies, and i have to restart the
gumstix. Anyone had the same problem?

Are the Gpios conected in any way? I have made some touch buttons and
conected them to the gumstix. This works fine, i detect alle activit
on the corect  GPIOS and display them on screen, When i try to
comunicate with a another devise conected to the gumstix they stop
working, one is activated and stays high untill i restart the gumstix,
or if I reset the keys then the next button is activated. I have
tested the keys by them selves and have found nothing wrong with them.
any idears?
Are there any of the GPIOS that i shouldnt use? ( I dont use HW, FF or
SW-uart Gpios)

Thanks and regards
