#1. The debug links is UART over FTDI via the front panel of the GR716-CPCI- GR716-DEV board.. General I/O, SPI flash Prom and Debug-UART are used. The complete default configuration can be found in Error: Reference source not found. If this is your first time using the GR716 Development Board, please use this configuration as a starting point. -
Page 12: Plug-On Configuration Boards
Draft Plug-on configuration boards To avoid misconfiguration and driver contamination the GR-CPCI-GR716-DEV development board implements a simple scheme where the user can create custom plug-on boards to select connections between the GR716 device and interface driver/source. The plug-on boards are refereed to as GR716-CONFIG1 boards. - Page 13 Rev.: Date: 2019-05-02 Page: 13 of 31 Status: Draft Figure 2 GR-CPCI-GR716-DEV configuration board placements Connector Default Description Config0 Enables GPIO, UART, MIL-1553, PacketWire, CAN, SPI Master and Slave, SpaceWire and SPI4S over CMOS.

Page 23: Gr716-Board And Expansion Boards
This section describes how to install and the GR716-BOARD [RD2] and expansion boards on the GR-CPCI-GR716-DEV board. The GR716-CPCI-DEV board provides two sites with two 2x32 pin headers to allow the board to function as a carrier board for GR716-BOARD and Expansion Boards. -
Page 24: Software Development Environment
Bare C Cross-Compiler System is a toolchain to compile bare C or C++ applications directly on top of the processor without the servises provided by an operating system Cobham Gaisler also provides a set of debug tools. The GR716 platform is supported by the following: GRMON Used to run and debug applications on GR716-BOARD hardware. -
