1.. zephyr:board:: gr716a_mini 2 3Overview 4******** 5 6The GR716-MINI development board provides: 7 8* GR716 microcontroller 9* SPI Flash PROM, 32 MiB 10* SRAM, 2 MiB 11* FTDI USB interface for UART debug link (AHBUART) and application UART 12 (APBUART). 13* 4x MMCX connectors (2 ADC, 2 DAC) 14* Miniature 80 pin mezzanine connector (bottom side) 15 16Hardware 17******** 18 19Console Output 20============== 21 22By default, the kernel is configured to send console output to the 23first APBUART peripheral (apbuart0). The UART debug forwarding setting, 24if enabled in GRMON, is preserved. 25 26Programming and Debugging 27************************* 28 29Building 30======== 31 32Applications for the ``gr716a_mini`` board configuration can be built 33as usual (see :ref:`build_an_application`). 34In order to build the application for ``gr716a_mini``, set the ``BOARD`` 35variable to ``gr716a_mini``. 36 37The application is linked to the on-chip tightly coupled memory by 38default. 39 40Running on hardware 41=================== 42 43Connect with GRMON, then load and run the application. 44 45.. code-block:: console 46 47 $ grmon -u -cginit 0x00010000 -uart /dev/ttyUSB0 48 GRMON debug monitor v3.2.8 49 50 Copyright (C) 2020 Cobham Gaisler - All rights reserved. 51 For latest updates, go to http://www.gaisler.com/ 52 Comments or bug-reports to support@gaisler.com 53 54 Device ID: 0x716 55 GRLIB build version: 4204 56 Detected system: GR716 57 Detected frequency: 20.0 MHz 58 59 Component Vendor 60 AHB-to-AHB Bridge Cobham Gaisler 61 MIL-STD-1553B Interface Cobham Gaisler 62 GRSPW2 SpaceWire Serial Link Cobham Gaisler 63 SPI to AHB Bridge Cobham Gaisler 64 I2C to AHB Bridge Cobham Gaisler 65 CAN Controller with DMA Cobham Gaisler 66 CAN Controller with DMA Cobham Gaisler 67 AHB Debug UART Cobham Gaisler 68 AHB-to-AHB Bridge Cobham Gaisler 69 PacketWire Receiver with DMA Cobham Gaisler 70 PacketWire Transmitter with DMA Cobham Gaisler 71 GRDMAC DMA Controller Cobham Gaisler 72 GRDMAC DMA Controller Cobham Gaisler 73 GRDMAC DMA Controller Cobham Gaisler 74 GRDMAC DMA Controller Cobham Gaisler 75 Dual-port SPI Slave Cobham Gaisler 76 LEON3FT SPARC V8 Processor Cobham Gaisler 77 AHB-to-AHB Bridge Cobham Gaisler 78 AHB Memory Scrubber Cobham Gaisler 79 AHB-to-AHB Bridge Cobham Gaisler 80 AHB Debug UART Cobham Gaisler 81 Dual-port AHB(/CPU) On-Chip RAM Cobham Gaisler 82 Dual-port AHB(/CPU) On-Chip RAM Cobham Gaisler 83 Generic AHB ROM Cobham Gaisler 84 Memory controller with EDAC Cobham Gaisler 85 SPI Memory Controller Cobham Gaisler 86 SPI Memory Controller Cobham Gaisler 87 AHB/APB Bridge Cobham Gaisler 88 AHB/APB Bridge Cobham Gaisler 89 AHB/APB Bridge Cobham Gaisler 90 AHB/APB Bridge Cobham Gaisler 91 Memory controller with EDAC Cobham Gaisler 92 LEON3 Debug Support Unit Cobham Gaisler 93 AHB/APB Bridge Cobham Gaisler 94 AMBA Trace Buffer Cobham Gaisler 95 Multi-processor Interrupt Ctrl.
