.. _gr716a_mini: GR716-MINI Development Board ############################ Overview ******** The GR716-MINI development board provides: * GR716 microcontroller * SPI Flash PROM, 32 MiB * SRAM, 2 MiB * FTDI USB interface for UART debug link (AHBUART) and application UART (APBUART). * 4x MMCX connectors (2 ADC, 2 DAC) * Miniature 80 pin mezzanine connector (bottom side) .. figure:: ../../../../../../../../../zephyr/boards/sparc/gr716a_mini/doc/gr716a_mini.jpg :align: center :alt: GR716-MINI Development Board GR716-MINI Development Board (Credit: Cobham Gaisler AB) Hardware ******** Console Output ============== By default, the kernel is configured to send console output to the first APBUART peripheral (apbuart0). The UART debug forwarding setting, if enabled in GRMON, is preserved. Programming and Debugging ************************* Building ======== Applications for the ``gr716a_mini`` board configuration can be built as usual (see :ref:`build_an_application`). In order to build the application for ``gr716a_mini``, set the ``BOARD`` variable to ``gr716a_mini``. The application is linked to the on-chip tightly coupled memory by default. Running on hardware =================== Connect with GRMON, then load and run the application. .. code-block:: console $ grmon -u -cginit 0x00010000 -uart /dev/ttyUSB0 GRMON debug monitor v3.2.8 Copyright (C) 2020 Cobham Gaisler - All rights reserved.
