I've just check this on recent u-boot v2020.10 and Odroid U3 board. Lukasz will send updated patch soon (with proper alias entry). If you want to hack setting MAC address manually, this will work with the current patch: # setexp.b u0 *0x10000014; setexp.b u1 *0x10000015; setexp.b u2 *0x10000016; setexp.b u3 *0x10000017; fdt addr ${fdtaddr}; fdt set /soc/usb@12110000/hub@1/usbether@1 local-mac-address [ 0 0 ${u0} ${u1} ${u2} ${u3} ] > also can you update this patch for exynos5422-odroidxu3-lite.dts and > exynos4412-odroidu3.dts. Also odroid-x2 and odroid-xu. Lukasz will take care of them. Best regards

I've not sure that this ethaddr hack/workaround should be added to mainline uboot. Some other exynos based board have proper MAC address stored in EEPROM (for example Odroid XU4/HC1). I would leave it for the users to add it manually if it is really needed for now. > I am getting following error on Odroid U3+ and U-Boot 2020.10 > > Odroid # setexp.b u0 *0x10000014; setexp.b u1 *0x10000015; setexp.b > u2 *0x10000016; setexp.b u3 *0x10000017; fdt addr ${fdtaddr}; fdt set > /soc/usb@12110000/hub@1/usbether@1 local-mac-address [ 0 0 ${u0} ${u1} > ${u2} ${u3} ] > No FDT memory address configured.

For some versions it was ${fdt_addr}, the other used ${fdtaddr}. Please check which one is used for loading dtb and adjust the script. Best regards

Add a placeholder for a MAC address. A bootloader may fill it to set the MAC address and override EEPROM settings.
