Problems with AR4100 integration

I've developed an application using the TWR-K60N512 , TWR-SER and TWR-WIFI-AR4100 boards. On the tower system all is running well.

Then I've replicated the tower on a custom pcb and i've found that the Atheros chip ( AR4100 ) cannot be initiliazed correctly.

 

Reading the AR4100 datasheet ( See the following link : http://cache.freescale.com/files/wireless_comm/doc/data_sheet/AR4100_DataSheet.pdf?fpsp=1&WT_TYPE=Data%20Sheets&WT_VENDOR=FREESCALE&WT_FILE_FORMAT=pdf&WT_ASSET=Documentation , ) , I've found the following sentence :

"The AR4100 requires additional OTP programming during integration into end systems. More specifically, customer will need to program a MAC address and several additional bytes into the AR4100. See the 'Programming the AR4100 SIP and SPI Flash on the Freescale Tower' application note."

On the Freescale siste I cannot find the above application note.

Pls give me instructions on how to program the AR4100 MAC and all the rest  in order to put the AR4100 in correct operation !!!
