[AR4100P]: looking for alternative way to program MAC address  to WLAN chip

For factory production purpose, I need a different way to program the MAC to AR4100P's OTP. Host.exe or ath_console.exe is not preferred in this case.


What I have is the Atheros flash agent source code integrated into MQX running on k20d72m custom board.


Is there a way to program MAC directly from k20d72m MCU? I can't find a API from the flash agent above except for some definitions like


/* IOTFLASHOTP_PARAM_FORCE_MAC_OVERRIDE - instructs firmware to ignore any existing mac address

* in OTP and instead write the new mac address to otp. normally, if any mac address is found

* in OTP the firmware will avoid writing a new mac address to OTP. */

#define IOTFLASHOTP_PARAM_FORCE_MAC_OVERRIDE        (0x00000010)


from wifi_flash_agent\src\app\main.h but no source code for it.
