I followed the instructions on the wiki to export the devices, but instead of getting names in /sys/class/gpio like gpio45_ph27, I get just gpio45
I am using the Ubuntu image, would switching to Debian help?

Thanks. Ultimately, I went to program in python, and discovered the A20 python library handles it well. :-)
