Hello everyone,

I am using mangOH Green board with ubuntu OS Developer studio 5
I want to detect my inserted SD Card and access it in my application.

mux 9 command is giving error as ‘not found’ in my terminal window.

How can I achieve this ?
and at /dev , which file refers to SD card slot ?

Hi,
As per search on forum, I came to know that GPIOExpander and MuxControl service needed to be running on my mangOH green borad for SD card detection
I have downloaded it from github
but I am not able to run it on my board.
How to run it?, can any one tel me?
