Re: [U-Boot-Users] Device tree and u-boot passing MAC addressquestions

I recently encountered the same problem. By using the 'fdt b' command, I was able to see that the MAC addresses were not being filled in prior to calling the kernel.

Most device tree properties are not filled in until you execute the bootm command. The MAC address is one such property.

Adding aliases to the dtb file fixed my problem. (Search the mailing lists...)

It looks like U-Boot was updated before the device trees were updated. When the code for aliases was added to U-Boot, the code for older device trees should not have been removed.
