Driver Manager
|
|
--------------
|
|
|
|
The leon3 BSP includes an optional driver manager that handles drivers and
|
|
devices on the AMBA and PCI Plug & Play buses. The driver manager can either
|
|
be initialized manually by the user, or started automatically on startup by
|
|
setting the ``RTEMS_DRVMGR_STARTUP`` option. It can be configured to
|
|
automatically instantiate a driver for each hardware device found.
|
|
|
|
Drivers for the following devices are provided and handled via the driver manager:
|
|
|
|
* SpaceWire (GRSPW, GRSPW2, GRSPW2_DMA)
|
|
* SpaceWire Router (GRSPWROUTER)
|
|
* SpaceWire Time Distribution Protocol (SPWTDP)
|
|
* CAN - non-DMA (OCCAN) and DMA (GRCAN, GRCANFD)
|
|
- GPIO (GRGPIO)
|
|
- L2 Cache (L2CACHE)
|
|
- IOMMU (GRIOMMU)
|
|
- ADC/DAC (GRADCDAC)
|
|
- Timers (GPTIMER, GRTIMER)
|
|
- 1553 BC, RT and BM support (GR1553B)
|
|
- I2C Master (I2CMST)
|
|
- PCI (GRPCI2, GRPCI, PCIF)
|
|
- Memory Controller (MCTRL)
|
|
- Memory Scrubber (MEMSCRUB)
|
|
- Pulse Width Modulation Generator (GRPWM)
|
|
- CCSDS/ECSS Telemetry Encoder/Decoder (GRTM/GRTC)
|
|
- CSDS Time Manager (GRCTM)
|
|
- Ethernet (GRETH 10/100/1000) (requires network stack)
|
|
- Performance counters (L4STAT)
|
|
- Serial Peripheral Interface (AHBSTAT)
|
|
- AHB Status (AHBSTAT)
|

Build Configuration Options
|
|
---------------------------
|
|
|
|
The following options can be used in the BSP section of the ``waf``
|
|
configuration INI file. The ``waf`` defaults can be used to inspect the values.
|
|
|
|
``CONSOLE_USE_INTERRUPTS``
|
|
Use the Termios interrupt mode in the console driver (false by default).
|
|
|
|
``RTEMS_DRVMGR_STARTUP``
|
|
Enable the Driver Manager at startup (false by default).
