1. In sources/meta-phytec/meta-phytec-fsl/conf/machine/imx7d-phyboard-zeta-001.conf, remove the following lines for sterling LWB module support. This package builds out of tree kernel modules to add WiFi support for another device, so need it needs to be disabled in order to use the in kernel modulesWiFimodules:

   Code Block
   # Packages required for PEB-WLBT-03 (WiFi chip Laird Sterling LWB) # IMAGE_INSTALL_append = " kernel-module-laird-backports brcm-patchram-plus" # LWB_COMPLIANCE = "fcc"

   
   

2. Update the kernel defconfig to enable WiFi by adding a kernel patch to the linux yocto recipe: 

   Code Block
   FILESEXTRAPATHS_prepend := "${THISDIR}/${PN}-4.1.15:" SRC_URI += "file://0001-Revert-configs-imx7_phyboard_zeta_defconfig-disable-.patch"

   
   

   1. In sources/meta-phytec-fsl/recipes-kernel/linux/linux-phytec-fsl_4.1.15.bb, add the following lines:

      Code Block
      FILESEXTRAPATHS_prepend := "${THISDIR}/${PN}-4.1.15:" SRC_URI += "file://0001-Revert-configs-imx7_phyboard_zeta_defconfig-disable-.patch"

      
      

   2. In the same file, set copy_defconfig to occur after "do_patch" so that the updated defconfig is used:

      Code Block
      -addtask copy_defconfig after do_unpack before do_preconfigure +addtask copy_defconfig after do_patch before do_preconfigure

      
      

   3. Create the following directory which will hold the kernel patch:

      Code Block
      mkdir sources/meta-phytec-fsl/recipes-kernel/linux/linux-phytec-fsl-4.1.15/

      
      

   4. Download and add this patch to the newly created directory: 0001-Revert-configs-imx7_phyboard_zeta_defconfig-disable-.patch

3. Continue building the BSP as directed by the quickstart. Follow instructions for creating a bootable SD card as well.

4. Download the firmware and add it to the root file system of the SD card. Firmware for Intel Wifi devices are available Here. Make sure to download the correct firmware for you specific device. This was tested with WiFi Link 5300, which uses iwlwifi-5000-ucode-8.83.5.1. Download the tarball, extract, and copy ucode file to /lib/firmware/ on the root filesystem of the SD card.

   Code Block
   $ tar -xf iwlwifi-5000-ucode-8.83.5.1-1.tgz $ sudo cp iwlwifi-5000-ucode-8.83.5.1/iwlwifi-5000-5.ucode /media/<user>/7963f5ce-4ba0-4d28-8a28-0186812c5487/lib/firmware/; sync $ umount /media/<user>/7963f5ce-4ba0-4d28-8a28-0186812c5487/
