+Booting the ast2700fc machine
+^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
+
+AST2700 features four Cortex-A35 primary processors and two Cortex-M4
coprocessors.
+**ast2700-evb** machine focuses on emulating the four Cortex-A35 primary
processors,
+**ast2700fc** machine extends **ast2700-evb** by adding support for the two
Cortex-M4 coprocessors.
+
+To boot the AST2700 full-core machine, follow these steps:
+
+ 1. Configure an MTD drive for the four Cortex-A35 primary processors.
+ 2. Load:
+
+ - SSP (Secondary Service Processor) firmware on CPU 5 (``cpu-num=4``).
+ - TSP (Tertiary Service Processor) firmware on CPU 6 (``cpu-num=5``).
+
+.. code-block:: bash

+
+After starting QEMU, the serial devices will be redirected:
+
+.. code-block:: bash
+
+ char device redirected to /dev/pts/55 (label serial0)
+ char device redirected to /dev/pts/56 (label serial1)
+ char device redirected to /dev/pts/57 (label serial2)
+
+
+
+`serial0` is the console for the four Cortex-A35 primary processors, `serial1`
and `serial2` are the consoles for the two Cortex-M4 coprocessors.
+To connect to the console, use `tio` or other terminal emulator:
+
+.. code-block:: bash
+
+ $ tio /dev/pts/55
+ $ tio /dev/pts/56
+ $ tio /dev/pts/57
