Hello, Yet another newbie question.
I have got latest debian image on my beagle bone black. uname - r output: 4.9.45-ti-r57 and I noticed various gpio directory in /sys/class/gpio when I tried echo 69 > unexport it gave me permission denied. so I changed the permission of unexport file to be 666 and now when I try to use the same command it gives me an error: -bash: echo: write error: Invalid argument Can anyone please help... Ultimately I want to develop a C++ project to toggle LED which is connected to one of the pins... Any help regarding this matter is deeply appreciated.
