Try adding them under Additional custom capes part not the Override cape with EEPROM
###Additional custom capes uboot_overlay_addr4=/lib/firmware/BB-I2C1-00A0.dtbo uboot_overlay_addr5=/lib/firmware/BB-ADC-00A0.dtbo uboot_overlay_addr6=/lib/firmware/BB-UART4-00A0.dtbo #uboot_overlay_addr7=/lib/firmware/<file7>.dtbo ### I added UART4 there on my BeagleBoneBlack with Jessie on it and kernel 4.4-ti and it shows up as /dev/ttyO4.
