Starting with a brand-new, out of the box BBB, I flashed it with *https://rcn-ee.net/deb/flasher/saucy/BBB-eMMC-flasher-ubuntu-13.10-2014-03-27-2gb.img.xz*which is of course the 3.8.13-bone40 kernel. The analog inputs were enabled once the
# echo cape-bone-iio > /sys/devices/bone_capemgr.*/slots command was given. The raw analog inputs were then readable at */sys/bus/iio/devices/iio\:device0/in_voltage[0-7]_raw*. However, after reading the inputs over a period of time, I started seeing errors reading the inputs, the "Resource temporarily unavailable" others have reported. Know the support for iio was updated in later kernels. I decided to update the kernel to see if that made a difference. Using the update script at *https://rcn-ee.net/deb/saucy-armhf/v3.13.8-bone8/install-me.sh*, I updated to the latest pre-built kernel. Now, I see analog inputs with no additional prodding required (perhaps the magic is now buried in the boot sequence?), but I don't see all the inputs, just 3: */sys/bus/iio/devices/iio\:device0/* *in_voltage[4-6]_raw*. What am I missing? Is there something I need to enable/disable in the /boot/uboot/uEnv.txt?
