obtain information about the target board, download code and/or data,
modify memory on the target, and execute a downloaded program. These
transactions occur across the VMEbus in the case of the MVME5500.
MOTLoad uses one of four mailboxes in the Universe II as the inter-board
communication address (IBCA) between the host and the target.
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:
CR/CSR space for a board in the 1st slot will start at 0x0008.0000
CR/CSR space for a board in the 2nd slot will start at 0x0010.0000
CR/CSR space for a board in the 3rd slot will start at 0x0018.0000
CR/CSR space for a board in the 4th slot will start at 0x0020.0000
CR/CSR space for a board in the 5th slot will start at 0x0028.0000
CR/CSR space for a board in the 6th slot will start at 0x0030.0000
CR/CSR space for a board in the 7th slot will start at 0x0038.0000
CR/CSR space for a board in the 8th slot will start at 0x0040.0000
CR/CSR space for a board in the 9th slot will start at 0x0048.0000
CR/CSR space for a board in the ath slot will start at 0x0050.0000
CR/CSR space for a board in the bth slot will start at 0x0058.0000
CR/CSR space for a board in the cth slot will start at 0x0060.0000
For further details on CR/CSR space, please refer to the VME64
Specification, listed in
The MVME5500 uses a Tundra Universe II for its VME bridge. The offsets
of the mailboxes in the Universe II are defined in the Universe II User
Manual, listed in
for reference:
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
