title: Accessing GPIO Pins on Linux Embedded Running on a Raspberry Pi 3
body: <p>I am trying to currently make a c program that will make a light blink on a Raspberry Pi 3 with embedded linux installed. I am currently building the image for the OS using yocto, poky with the raspberry pi 3 and open embedded. The OS installs on the SD card and I can have managed to add the layer that runs applications and have made a simple hello world. I am now trying to access the GPIO pins but having trouble with this.</p>
