Thanks for the reply Andrew. I got pulled off this project and am just getting back to it now.
I added some debug output in wifi.c, and it looks like it's able to open a connection to wpa_supplicant, although it seems to fail once and succeed the second time. To answer your questions: - I'm using the version of wpa_supplicant that came with Android (I'm using the Wandboard SDK 4.4.2). - I added the dhcpcd section in init.rc. I also changed the wpa_supplicant section to use wext instead of nl80211. - I haven't made any changes to wpa_supplicant.conf as it looked correct for my use - I'm not using p2p. But I can run scan and scan_results in wpa_cli and they both work correctly.
