Configuring Edison Arduino Pins for Analog input Ai0

[Manish_P_]

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?

Intel, any solutions to 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.
