 For RW610/612 board, before compiling the CPU3 image, there are three macros need to be configured to determine which fw to download.
   - CONFIG_SUPPORT_WIFI
   - CONFIG_SUPPORT_BLE
   - CONFIG_SUPPORT_BLE_15D4
 
-By default: Enable wifi and ble (15d4 is not supported yet)
-wifi+ble
-  - CONFIG_SUPPORT_WIFI=y
-  - CONFIG_SUPPORT_BLE=y
-  - CONFIG_SUPPORT_BLE_15D4=n
+Build steps:
+1) Add the below macros to "zsdk/samples/nxp_mfg_bridge/prj.conf" file.
+    CONFIG_SUPPORT_WIFI=n
+    CONFIG_SUPPORT_BLE=n
+    CONFIG_SUPPORT_BLE_15D4=n
 
-Here are some example about fw be used:
