Gaisler Driver Library (GRDRV)

The Gaisler Driver Library is a suite of drivers developed according to ECSS category B standard. The drivers have been developed for the GR765 NOEL-V platform using RTEMS 6.2 SMP.

Drivers for the following peripherals are available:

• AHB Status Register: Driver for logging correctable and non-correctable error responses.

• APB UART: Driver for transferring arbitrarily sized data buffers over UART.

• CAN-FD Controller: Driver for CAN controller with Flexible Data-rate support.

• Clock-gate Unit: Driver to manage clock gated cores to reduce system power consumption.

• General Purpose I/O Port: Driver for general purpose input/output (GPIO) pins.

• FTADDR Memory Controller: Driver for accessing memory scrubbing and error counters to help identifying memory errors.

• MIL-STD-1553B Controller: Driver for the MIL-STD-1553B data bus, including bus controller, remote terminal, and bus monitor.

• SpaceFibre Controller: Driver for SpaceFibre communication with virtual channel and broadcast channel support.

• SpaceWire DMA Controller: Driver for SpaceWire communication via the SpaceWire router.

• SpaceWire Router: Driver for configuring the SpaceWire router.

• SPI Master Controller: Driver for a Serial Peripheral Interface (SPI) master controller with standard, dual, and quad support.

• Watchdog: Driver used to kick watchdog and handle graceful shutdown.
