WPAoH Device-Side Driver

Set up the compilation environment, and run ameba.py menuconfig to access the configuration interface

Select WHC_DEV.

(Top) -> CONFIG WHC INTF -> WHC_MODE
----Configuration----
    ( ) WHC_IPC
    (X) WHC_DEV
    ( ) WHC_HOST

Select the desired interface.

(Top) -> CONFIG WHC INTF -> HW INTERFACE
----Configuration----
    (X) WHC_INTF_SDIO
    ( ) WHC_INTF_USB
    ( ) WHC_INTF_SPI

Note

RTL8721F:

To ensure stable USB operation, when WHC_INTF_USB is selected, the SoC defaults to 1.0V with CPU at 240MHz. If other requirements are needed, you can also configure it manually:

(Top) -> CONFIG User Config -> Clock Configuration -> SoC Clock Config
(X) [2] 1.0V, Audio(98.304MHz)/USB, CPU 240MHz
( ) [3] 1.0V, Audio(45.1584MHz)/USB, CPU 240MHz
( ) [5] 1.0V, RMII/USB, CPU 320MHz
( ) [6] 1.0V, Audio/USB, CPU 320MHz
( ) [7] 1.0V, Audio/RMII, CPU 333.3MHz

The following IC models should select Boot Source as follows. ICs not listed above do not need to select Boot Source:
RTL8721F:
(Top) -> CONFIG WHC INTF -> Boot Source (X) Boot From Flash ( ) Boot From HCI

Select modules based your mode, Please reference WHC Wi-Fi Configuration Options and Operating Modes for more informations.

(Top) -> CONFIG WHC INTF -> WHC config
----Configuration----
   (X) Support WHC CMD PATH
   (X) Support WHC WIFI API PATH
   ( ) Support WHC SUPPLICANT OFFLOAD
   ( ) Support WHC DEV TCPIP KEEPALIVE

Note

If you want to enable TCP/IP keep-alive on Device-side, please select Support WHC DEV TCPIP KEEPALIVE.

Select Wi-Fi NAN or Wi-Fi P2P based on your need:

(Top) -> CONFIG WIFI
----Configuration----
    (X)ENABLE WIFI --->
      CONFIG WIFI MODE --->
         (X) ENABLE NAN
         ( ) ENABLE P2P

Note

Wi-Fi NAN or Wi-Fi P2P can only operate in Linux WPAoH mode.

Save the menuconfig configuration.
Run ameba.py build to generate the firmware: boot.bin, app.bin.
Use the image tool to download the firmware to the development board.
