3.3 Configuration required for Board Device Tree (DTS/DTB)

The device tree is a set of files in the Linux source that describe the hardware platform. In order to integrate WilInk8 the file needs to have the right configuration to integrate with required hardware interface. For WiLink8 WLAN functionality these include

  • SDIO configuration
  • WL_EN GPIO configuration
  • WL_IRQ GPIO configuration
  • Power control configuration
  • MMC configuration

The default TI processor SDK dts/b file has already enabled the required configurations. The files are automatically chooses at boot time based on the HW platform used. For details of required configurations, see AM335x_evm.dts. Note that these settings may need to be modified based on specific hardware platform used.
