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)

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.
