Just a follow up, because I spent several iterations tracking this issue down further. If you do install the generated u-boot deb package and reboot, you will most likely see the following error wl1271_sdio: probe of mmc1:0001:2 failed with error -61 in your kernel log.

See the following steps to get the TI wl18xx drivers to work on the Cubox with the I4P Rev 1.5 SOM. Step 1) Boot with the Armbian base image (Armbian_5.20_Cubox-i_Ubuntu_xenial_4.7.3). The 3.14.79 base image also works however will require a different dpkg install command to overwrite the 3.14.79 kernel. Step 2) Build a new kernel with Armbian build tools, note this only works with the 'DEV' kernel branch because SolidRun provides all the necessary DTS files. Edit the compile.sh script and change KERNEL_CONFIGURE="yes" to customize the kernel configuration. The relevant modules you will need to select are: CONFIG_WL_TI=y CONFIG_WL1251=m (In my last working test I enabled this module but it may not be necessary) CONFIG_18XX=m CONFIG_CORE=m CONFIG_WLCORE_SDIO=m CONFIG_WILINK_PLATFORM_DATA=y Step 3) Copy the built kernel deb packages found in output/debs to the Cubox. linux-dtb-dev-cubox_5.27_armhf.deb linux-firmware-image-dev-cubox_5.27_armhf.deb linux-headers-dev-cubox_5.27_armhf.deb linux-image-dev-cubox_5.27_armhf.deb Note: DO NOT copy the generated linux-u-boot-dev-cubox-i*.deb Step 4) Install the packages on the cubox; dpkg -i linux-dtb-dev-cubox_5.27_armhf.deb dpkg -i linux-firmware-image-dev-cubox_5.27_armhf.deb dpkg -i linux-headers-dev-cubox_5.27_armhf.deb dpkg -i linux-image-dev-cubox_5.27_armhf.deb Update your /etc/network/interfaces file to match your WiFi configuration. Step 5) Reboot and WiFi should work.
