I think I'm on the right path :) 1. Included SUNXI_SETUP_REGULATORS=0 to the bl31 make 2. Changed the phy mode on arch/arm/dts/sun50i-h6-orangepi-one-plus.dts From rgmii-id to rgmii More info on [1][2][3] 3. Added this configs to configs/orangepi_one_plus_defconfig: CONFIG_SPL_SPI_SUNXI=y CONFIG_SUNXI_NO_PMIC=y CONFIG_SUN8I_EMAC=y Result: U-Boot 2023.04-gfd4ed6b (Apr 03 2023 - 20:38:50 +0000) Allwinner Technology CPU: Allwinner H6 (SUN50I) Model: OrangePi One Plus DRAM: 1 GiB Core: 55 devices, 17 uclasses, devicetree: separate WDT: Not starting watchdog@7020400 MMC: mmc@4020000: 0 Loading Environment from FAT...
