We have a Revision C board running debian, and wish to use a couple of the GPIO channels from within the (C++) software we are developing. This requires writing to the "file" /sys/class/gpio/export, but this requires root permission. In bash I can just "sudo su", but this is surely not going to work from C++?
Presumably if I logged in as root and ran my code, the permissions would be correct. However the board boots to the desktop with "debian" as the default user. Can this be changed to root and how? -- For more options, visit http://beagleboard.org/discuss --- You received this message because you are subscribed to the Google Groups "BeagleBoard" group.
