Marvell EBU:Armada 38x
Note about the BootROM UART selection
While the UART-to-USB FTDI chip is wired on UART1, the BootROM only interacts on UART0. Both UARTs are available on the top side of the board through two horizontal 3-pin male headers, the one directer towards the mini-USB connector is UART1. The opposite one shall be used to enter BootROM recovery mode.
