SMART Embedded Computing MVME3100 Installation And Use Manual page 57

CR/CSR slave addresses configured by MOTLoad are assigned according to the
installation slot in the backplane, as indicated by the VME64 Specification. For reference,
the following values are provided:
Slot Position
1
2

For further details on CR/CSR space, please refer to the VME64 Specification, listed in
Appendix B, Related Documentation
The MVME3100 uses a Discovery II for its VME bridge. The offsets of the mailboxes in the
Discovery II are defined in the Discovery II User Manual, listed in
Documentation
Mailbox 0 is at offset 7f348 in the CR/CSR space
Mailbox 1 is at offset 7f34C in the CR/CSR space
Mailbox 2 is at offset 7f350 in the CR/CSR space
Mailbox 3 is at offset 7f354 in the CR/CSR space
The selection of the mailbox used by remote start on an individual MVME3100 is
determined by the setting of a global environment variable (GEV). The default mailbox is
zero. Another GEV controls whether remote start is enabled (default) or disabled. Refer to
the Remote Start appendix in the MOTLoad Firmware Package User's Manual for remote
start GEV definitions.
The MVME3100's IBCA needs to be mapped appropriately through the master's VMEbus
bridge. For example, to use remote start using mailbox 0 on an MVME3100 installed in slot
5, the master would need a mapping to support reads and writes of address 0x002ff348 in
VME CR/CSR space (0x280000 + 0x7f348).
