i'm not quite sure what you're asking, but you can't directly access the GPIO lines on the audiostix. you have access to a file in /proc/ that has the register values in it. do an lsmod to see if gpio is loaded, and if so, snoop around in / proc for the ac97 files. i can't find the exact path to the ac97 path, but its under /proc somewhere. look for audio. greg On Aug 16, 2006, at 4:54 AM, Alexandre Pereira Nunes wrote: > Daniel Winsor escreveu: > >> Can someone very for me if this is true.... >> If it is, it would explain why my gpio lines are not working... >> >> Commit by craig on trunk :: >> 14:07 on Jul 19 gumstix-buildroot >> r1053 >> /target/device/Gumstix/basix-connex/kernel-patches/ucb1400-ac97- >> audio.patch: >> >> Add /proc/gpio support or ucb1400's GPIO lines via ac97 >> >> >> My kernel is : >> Linux version 2.6.11gum (craig@azazel) (gcc version 3.4.2) #1 Wed Feb >> 1 16:53:57 PST 2006 >> >> Thanks Dan. >> > Well at first, your kernel is dated February 1, the change was > commited > to the buildroot on Jul 19, it would be quite interesting if that > would > just propagate to your gumstix's kernel without any action, > wouldn't it? :-) > > But I don't see how that could be related to your problem anyway. > > - Alexandre > > ---------------------------------------------------------------------- > --- > Using Tomcat but need to do more?
