Hello Kevin

I've never tried using the jumpers to set the VME address, so I can't answer with any authority on that point.  However, using the jumpers should not be necessary if you are using a VME-64X crate.

To initialize and EVG in slot 2 to have a VME address of "0x100000", with IRQ Level 3 and IRQ vector 4 the call to mrmEvgSetupVME would look something like:

mrmEvgSetupVME ("EVG-1", 2, 0x100000, 3, 4)
where:
 "EVG-1" is the "name string you wish to associate with this EVG"
 "2" is the slot it is in.
 "0x100000" is the VME address (in A24 space for the EVG, in A32 space for the EVR) you want the card to have
 "3" is the IRQ level, and
 "4" is the IRQ vector.

The software uses VME CR/CSR addressing to set the card in slot 2 to whatever VME address you select.
The VME address and IRQ vector must be chosen to not conflict with other VME boards and also be in a valid range for your environment.  Since you are running RTEMS, Michael Davidsaver can probably advise you about what would be valid values for the VME address and IRQ vector would be.

HTH.
