Hi Robert,

To get eth2 to link, I put this MAC in my device tree:
local-mac-address = [ 00 E0 0C 00 02 FD ];
Otherwise the kernel just sees a series of zero's . Is this change on purpose and I missed what I need to do now?
I recently encountered the same problem. By using the 'fdt b' command,
I ^ "fdt p" I presume. |
Sorry, I should have listed all the steps: tftp 10000 filename.dtb # load the dtb fdt a 10000 # tell fdt where it loaded fdt b # do the board specific setup (fills in MAC) fdt p # verify the values are correct
was able to see that the MAC addresses were not being filled in prior to calling the kernel.
Adding aliases to the dtb file fixed my problem. (Search the mailing lists...)
Best regards, Joe
