Hi Eric! Sorry I forgot we had an excellent how-to guide already :) 
My apologies for the confusion. Either service should work. You don't need both. 
As per your error message, have you waited out for a minute after the first time you saw that message?
The service fails the very first time, but it automatically tries again and succeeds after a min. In other words, it is not the perfect solution. 
 
Let me know,

Adam

Hi Adam,

I am using the Gumstix Overo with yocto build
I tried your method to enable the wpa_supplicant service. Besides, I did the following
1. Remove the wlan0 setup script in /etc/network/interfaces;
2. Add the systemd service to start the wifi as suggested here: http://gumstix.org/software-development/how-to/252-bring-up-wifi-on-a-yocto-project-image.html 
So total two systemd services needed to bring the wifi up?

But cannot work and show the error "IPv6: ADDRCONF(NETDEV_UP): wlan0: link is not ready". I am also wondering the wireless networking can use IPv4 instead? Thanks a lot.

Eric
