Hello faimbs, the USER LEDs are allready connected to GPIO-1, pins 21 to 24. By default these pins are configured as outputs.
An easy (and fast) alternative to control USER LEDs is libpruio <http://beagleboard.org/project/libpruio/>. No need for file access to control the status, just call a function to switch the LED on or off. Find the example sos.c in the package that makes the USER LED-3 blinking in SOS code: - description: http://users.freebasic-portal.de/tjf/Projekte/libpruio/doc/html/ChaExamples.html#SubExaSos - source code: http://users.freebasic-portal.de/tjf/Projekte/libpruio/doc/html/sos_8c_source.html *libpruio can do the pin muxing and control all GPIOs (a*s well as ADC inputs)*. You only need a simple device tree overlay to switch on the PRUSS*. All the other stuff is in your source code (single source). Your program doesn't need root privileges (but the user needs read/write access to */dev/uio5*, see DOC: Preparation <http://users.freebasic-portal.de/tjf/Projekte/libpruio/doc/html/ChaPreparation.html> for details).
