5.8 WILC Support for Desired Kernel Version
By configuring the buildroot with
                        sama5d27_som1_ek_graphics_defconfig file, WILC Driver
                    support will be added to the kernel image that generate along with the buildroot
                    build and is available at
                        buildroot-at91/output/build/linux-linux4sam_6.2/. If the
                    user needs control on the kernel version, the user must download the new kernel
                    and build a new Image Tree Blob (.itb) file, and replace the
                    file present in the microSD Card. 
.itb) file with WILC driver support is previously discussed
                in Building the Component, the same
                procedure is applicable here as well.
