Configuring IO18, IO19 for I2C connectivity on Intel Edison Kit for Arduino Intel Edison Kit for Arduino Hardware Guide instructs: 

echo 28 &gt; /sys/class/gpio/export
echo 27 &gt; /sys/class/gpio/export
echo 204 &gt; /sys/class/gpio/export
echo 205 &gt; /sys/class/gpio/export

echo mode1 &gt; /sys/kernel/debug/gpio_debug/gpio27/current_pinmux
echo high &gt; /sys/class/gpio/gpio214/direction


However line 3 already gives an error:

echo: write error: No such device


Any suggestions on how to enable I2C?
It was a strange problem which we were not able to resolve in an acceptable manner after all.

The problem disappeared after we re-flashed the device.
