WiFi Host Driver Board Support Package Integration Release Notes

This library helps streamline the process of getting the WiFi Host Driver (WHD) setup and running with a Board Support Package (BSP) that includes a WLAN chip.

What's Included?

APIs for setting up the WHD interface with the BSP's SDIO interface.
APIs for connecting WHD to LwIP/NetXDuo memory buffers (whd_buffer_funcs_t)
Framework for connecting WHD to LwIP/NetXDuo network interface (whd_netif_funcs_t)

What Changed?

v2.3.0

Added support for CAT5.
Added support for IOCTL buffers greater than max MTU for CAT5.

v2.2.1

Allow BSP to override default configuration of WL_REG_ON and WL_HOST_WAKE pins.

v2.2.0

Fixed issue where some 3.0-style BSPs were inappropriately using SDIO interface.

v2.1.0

Added support for dyanmically allocated NetX Duo packets to support WHD IOVARs with payloads larger than MTU.
Added support for NetX Duo
Made SDIO initialization more robust

v2.0.0

Added support for different communication protocols (SDIO, SPI, DMA) between MCU and Radio
Card initialization process improvements. Code now checks whether SDIO device supports 1.8V signaling, and, if it does, performs the actions needed in order to switch to 1.8V.
Added support for overriding the default country code by defining CY_WIFI_COUNTRY to a value from whd_country_code_t.
Added argument to cybsp_wifi_init_primary_extended() to set WHD initialization parameters
SDIO frequency is increased to 50 MHz if High Speed Mode is supported
Added support for HAL API v1 or v2
Minimum required wifi-host-driver library version for this release - 2.0.0

v1.2.0

Fixed possible memory corruption issue introduced with changes from v1.1.0

v1.1.2

Robustness update for WLAN initialization

v1.1.1

Update network buffer allocation for improved performance

v1.1.0

Fixed a memory leak when shutting down the WHD interface
Minor code style cleanups
