| .. zephyr:board:: gr716a_mini |
| |
| 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) |
| |
| 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. |
