If SPL_OF_CONTROL is being added, why do you need to manually add the stuff above for the serial port? Checkout the da850-evm-u-boot.dtsi file. I adds the device tree entries for the serial port to appear in the SPL DTB. See http://git.denx.de/?p=u-boot.git;a=commit;h=f7c1d53605d9ec528abacda9ba1763c67221fc88 > CONFIG_DEFAULT_DEVICE_TREE="da850-lcdk" > +CONFIG_SPL_OF_PLATDATA=y > CONFIG_ENV_IS_IN_NAND=y > CONFIG_NET_RANDOM_ETHADDR=y > CONFIG_DM=y > +CONFIG_SPL_DM=y > CONFIG_DM_I2C=y > CONFIG_DM_I2C_COMPAT=y > CONFIG_SYS_I2C_DAVINCI=y > @@ -53,8 +56,10 @@ CONFIG_SPI_FLASH_STMICRO=y > CONFIG_SPI_FLASH_WINBOND=y > CONFIG_MII=y > CONFIG_DRIVER_TI_EMAC=y > +CONFIG_SPECIFY_CONSOLE_INDEX=y > CONFIG_DM_SERIAL=y > CONFIG_SYS_NS16550=y > CONFIG_SPI=y > CONFIG_DAVINCI_SPI=y > CONFIG_USE_TINY_PRINTF=y > +# CONFIG_SPL_OF_LIBFDT is not set > -- > 2.21.0 > _______________________________________________ U-Boot mailing list U-Boot@lists.denx.de https://lists.denx.de/listinfo/u-boot
