6.5Firmware Settings

The following sections provide additional information pertaining to the MVME7100 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.

VME settings in MOTLoad are preserved through the use of Global Environment Variables (GEVs). Configuration GEVs are executed only at power-on reset. Therefore, if VME configuration changes are implemented through vmeCfg and board reset must be effected for the changes to be implemented in MOTLoad.

6.5.1Default VME Settings

As shipped from the factory, the MVME7100 has the following VME configuration programmed via Global Environment Variables (GEVs) for the Tsi148 VME controller. The firmware allows certain VME settings to be changed in order for the user to customize the 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 Tsi148 User Manual, listed in Appendix B, Related Documentation.
