Find example code in the libpruio <http://beagleboard.org/project/libpruio/> project. The CPU balls should be in mode 7 after boot / reset, allready -> no DTBO necessary. Check it by executing analyse example <http://users.freebasic-portal.de/tjf/Projekte/libpruio/doc/html/_cha_examples.html#SubSecExaAnalyse>, here I get Header Pins: ... P8_09, GPIO 2/05: input, pullup P8_10, GPIO 2/04: input, pullup ... For IO, set or read in GPIO-2 subsystem bits 5 (P8_09) and 4 (P8_10). Note: the subsystem GPIO-2 is disabled by default: ...
