Where to find Wi-Fi Software Drivers
NXP Recommends using Wi-Fi source code drivers available from GitHub based on the following decisions:

Software Drivers NXP Processor
Linux software drivers on NXP host processor (i.MX6, 7, 8 or 9)
Pre-built binary demo files for each quarterly BSP release are available here:
Software Drivers NXP Microcontrollers
RTOS software drivers on NXP host processor (MCX, MCU, or i.MX RT)
Software Drivers Non-NXP Processor
Non-nxp host processor with Linux or Android
Software Drivers Non-NXP Microcontrollers
Non-nxp host MCU RTOS
In addition to GitHub, RTOS drivers are available on NXP web site and as an Open CMSIS Pack from ARM:
