You can access the gpio functions from the shell by writing to members of this directory, e.g. set direction, set on/off.
In a normal linux system you can do the same thing by doing an open() and then write(). In a sandboxed application this results in permission problems, even when these members have been assigned in .cdef.
Has anyone been able to make this work in a sandboxed application? I’m aware of the le_gpio routines but I’m having some issues with them. Thanks.
