Disassembling A385 BootROM binary reveal how BootROM interprets strapping pins for Boot Device Mode. All possible options are:
0x00..0x07 -> Parallel NOR 0x08..0x15 -> Parallel NAND 0x16..0x17 -> Parallel NOR 0x18..0x25 -> Parallel NAND 0x26..0x27 -> SPI NAND 0x28..0x29 -> UART xmodem 0x2a..0x2b -> SATA 0x2c..0x2d -> PCI Express 0x2e..0x2f -> Parallel NOR 0x30..0x31 -> SD / eMMC 0x32..0x39 -> SPI NOR 0x3a..0x3c -> Parallel NOR 0x3d..0x3e -> UART debug console 0x3f -> Invalid
Note that Boot Device Mode Options in A38x Hardware Specifications is incomplete.
