4.5Firmware Settings

The following sections provide additional information pertaining pertaining to the MVME5500 VME bus interface settings as configured by MOTLoad. A few VME settings are controlled by hardware jumpers while the majority of the VME settings are managed by the firmware command utility vmeCfg.

4.5.1Default VME Settings

As shipped from the factory, the firmware on the MVME5500 will program default values into the Universe II VME Interface chip. The firmware allows certain VME settings to be changed in order for the user to customize his/her environment. The following is a description of the default VME settings that are changeable by the user. For more information, refer to the MOTLoad User’s Manual and Tundra’s Universe II User Manual, listed in Appendix C, Related Documentation.

zVME3PCI Master Enable = Y

N = Do not set up or enable the VMEbus Interface. Y= Set up and enable the VMEbus Interface.

zPCI Slave Image 0

This image is set to zeroes and thus disabled.

zPCI Slave Image 1 Control = C0820000

Sets LSI1_CTL to indicate that this image is enabled, write posting is enabled, VMEbus data width is 32 bits, VMEbus address space is A32, data and non-supervisory AM encoding, no BLT transfers to the VMEbus, and to accept addresses in PCI memory space.

zPCI Slave Image 1 Base Address Register = 91000000

Sets LSI1_BS to indicate that the lower bound of PCI memory addresses to be transferred to the VMEbus by this image is 0x91000000.

zPCI Slave Image 1 Bound Address Register = B0000000

Sets LSI1_BD to indicate that the upper bound of PCI memory addresses to be transferred by this image is 0xB0000000.

zPCI Slave Image 1 Translation Offset = 70000000
