I am running an application that access GPIO using Centos Minimal on Raspberry Pi3 board. when I tested with root everything worked fine. However, with non root user, it did not work.
I followed every tricks I could found on the web and got all chown and chmod to set correct access to the /sys/class/gpio/gpiox/direction and /sys/class/gpiox/value files. However, it still could not control the GPIO. Please note that root always works fine. I appreciate if anyone can tell me that it is the limitation of Centos Minimal on Raspberry Pi or there is the way to over come this issue.
