Freerunner GPIO locations
hi all, apologies if this question is answered elsewhere, i've done lots of searching of the openmoko wiki and the web, and can't find an answer i'd like to interface my freerunner with hardware switches to control some software. i believe gpio is the best way to do this, and have help from various bodies at my local maker space to do so. problem is, i can't locate the gpio pins on the motherboard. are there any schematics out there with their location? ideally something which relates them to the nodes in /sys/class/gpio/ cheers, -- robin What the world needs now is love sweet love ___ Openmoko community mailing list community@lists.openmoko.org http://lists.openmoko.org/mailman/listinfo/community

The i2c pad locations are known: http://chonyota.net/freerunner/FRNBv2/FRNBv2-Installation.pdf Good Luck, Ben ___ Openmoko community mailing list community@lists.openmoko.org http://lists.openmoko.org/mailman/listinfo/community
