8.16. sparc (SPARC / LEON)#

8.16.1. erc32#

TODO.

8.16.2. leon2#

This BSP supports LEON2 systems, in particular the Microchip AT697F. The following default build configurations are provided:

  • leon2 - A generic LEON2 system with memory at 0x4000000.

  • at697f - For the AT697F. Built with -mcpu=leon -mfix-at697f.

The BSP contains UART, timer, and interrupt controller drivers. Drivers for PCI are available through the driver manager.

8.16.3. leon3#

This BSP supports the LEON3/4/5 systems from Cobham Gaisler. The following default build configurations are provided:

  • leon3 - A generic LEON3/4/5 system with memory at 0x4000000.

  • ut700 - For the UT700. Built with -mcpu=leon3 -mfix-ut700.

  • ut699 - For the UT699. Built with -mcpu=leon -mfix-ut699.

  • gr712rc - For the GR712RC. Built with -mcpu=leon3 -mfix-gr712rc.

  • gr740 - For the GR740. Memory located at address 0x0.

The BSP contains UART, timer, and interrupt controller drivers. Drivers for additional peripherals are available through the driver manager.

8.16.3.1. 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)

8.16.3.2. 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).
