Configuring Edison Arduino Pins for Analog input Ai0

Manish_P_ — Sun, 22 Feb 2015 16:22:46 GMT

I am running an Intel edison arduino board with Yocto, edison updated to libmraa 0.6.0.

When I try to set up for analog in, I get the error message below.

# echo 214 > /sys/class/gpio/export

sh: write error: No such device

(e.g. as in page 28/section 11.5 of http://download.intel.com/support/edison/sb/edisonarduino_hg_331191007.pdf)

I have a 12V 2A supply connected to the system. I have rebooted the board, but the error persists.

Any suggestions on how to fix this problem?

Isnt GPIO 214 already exported ?

can you try to reboot and just ls /sys/class/gpio/ ?

Yes as rzr says try reboot the board and check if gpio214 is already exported by using command ls /sys/class/gpio/.

If it is not found then try to export and # echo 214 > /sys/class/gpio/export and check the result.
