→‎Enabling dual Ethernet configuration in linux kernel
Alternatively kernel and device tree can be built from sources with the following procedure:
* update Bora kernel repository (as described [[Bora_Embedded_Linux_Kit_(BELK)#Updating_the_repositories_from_BELK_2.1.0_to_BELK_2.2.0|here]])
* apply build the patch <code>0001-dts-bora-add-ETH1-phy-supportan006.patchdtb</code> included in the pre-build binaries packagedevicetree
* build the updated kernel source as usual.
 
Here is the patch to enable dual Ethernet:

Put the binaries on the first (FAT32) partition of your BELK SD card, overwriting the original one if needed. Please note that you need the following files:
* <code>uImage</code>
* <code>fpga.bin</code>
* <code>u-boot.img</code>
* <code>uEnv.txt</code>
