Hi @howardyu , 

You can check if the MAC address is updated by running ifconfig wlan0 and checking the HWaddr parameter.

Hi @howardyu

Using the Manufacturing firmware or mfg Firmware you can write the macaddress to the OTP, if you do not have the mfg firmware you can request it from the module vendor.

Once you have the mfg firmware you can run the following command to write the MAC to the OPT
sudo ./wl wrvar macaddress=00:11:22:33:44:55 to write the mac to OTP

If you wish to write it on the OTP file itself you can follow the procedure described in section "5.1 Programming Basic Parameters into OTP Memory" of the OTP Memory Programming and NVRAM Development for CYW4373 

You can also refer to the following post for reference. https://community.infineon.com/t5/AIROC-Wi-Fi-and-Wi-Fi-Bluetooth/Linux-wifi-MAC-address/m-p/274911#...
