Not really, the U-Boot .dtbs should always work with U-Boot's Ethernet driver. What doesn't work at the moment is to reuse U-Boot's .dtb for the kernel - which is fixed by my series you mention below. > I'll try with > the latest DTB updates you sent to the list earlier to see if that changes > anything on the Ethernet front. Yeah, you can try, but I don't expect much changes here, as U-Boot's .dtb and the U-Boot driver should always work together (hence the order of the patches in my series). Can you do me a favour and check the schematics to see how the PHY is powered? Cheers, Andre. -- You received this message because you are subscribed to the Google Groups "linux-sunxi" group.
