Serial

The QB serial driver can be configured using the serial node in QB DTB file. For example:

serial {
    serial =
        /* WordLength, Parity, StopBits, BaudRate, Port */
        <8 0 1 115200 0>;
};

Note:

The Quickboot serial device (UART) is predefined by th early boot loader components MB1 and MB2. For this reason the instance number fo the serial device is not supported, and multiple instances of the serial device cannot be defined.
