It is wired to the on-board FT4232 +USB bridge, so a single USB cable carries it and no separate USB serial +adapter is needed. The bridge presents four ports, of which UART0 is the +third; on Linux that is usually ``/dev/ttyUSB2``, the first of the four +being the JTAG interface: + +.. code:: console + + $ screen /dev/ttyUSB2 115200 + +Buttons and LEDs +================ + +The board has four LEDs on GPIO lines 107 to 110 and one push button, ``OK``, +on GPIO line 6. NuttX does not drive any of them yet. + +Power Supply +============ + +The board is powered through its barrel jack. The core rails, including the +NPU rail, are set by regulators on I2C bus 1, which NuttX leaves alone: the +firmware has already configured them by the time NuttX starts, and writing to +them changes a core voltage. + +RISC-V Toolchain +================ + +Install `xPack GNU RISC-V Embedded GCC (riscv-none-elf) +`_ and +add its ``bin`` directory to ``PATH``, as described for the +:doc:`PINE64 StarPro64 <../starpro64/index>`. + +Building NuttX +============== + +Configure and build: + +.. code:: console + + $ cd nuttx + $ tools/configure.sh eic7700-evb:nsh + $ make + +Then build the applications filesystem and package it with the kernel: + +.. code:: console + + $ make export + $ pushd ../apps + $ tools/mkimport.sh -z -x ../nuttx/nuttx-export-*.tar.gz + $ make import + $ popd + $ boards/risc-v/eic7700x/common/tools/mkimage.sh + +The image is the kernel, then padding, then a RAM disk holding the +applications.
