petalinux 2016.4 and wilink : wpa_supplicant not working

Hello all,
I am working on integrating the ti wilink on my custom unit which is dual core zynq platform. I am using petalinux 2016.4. I followed the instructions from  and also the instructions from one of the forum members to integrate the chip. I see that wilink chip is coming up but now when I try to run the wpa_supplicant or wpa_cli or iw it shows me 
-sh: /usr/local/sbin/wpa_supplicant: No such file or directory 
I get the same error for all the tools like iw, crda, wpa_cli, wpa_passphrase 
Can somebody help me understand why am I getting this error?
I created a install template app and then changed the .bb file to cp the tools and libraries in the rootfs.

We are no longer supporting

We are no longer supporting the TI WiLink. Would you consider switching to the Murata 1DX? We have found it to work much better. You will find it on MiniZed, or you can add a Pmod to any other development board, like ZedBoard
