WF200 Firmware

During the Initialization and Configuration phase, the host has to send a signed and encrypted firmware to the WF200. In the FMAC driver, the firmware information is provided by the host through the following functions:

Depending on the host implementation, the firmware can be stored in different formats. For example, it can be stored in a simple C array or be part of a more complex file system. The firmware download phase is handled through the sl_wfx_download_run_firmware() function. The latest WF200 firmware can be found on a public GitHub repository .

In addition to the WF200 firmware, the file contains a keyset, signature, and hash to authenticate the firmware.
