11.2 Configuration ROM

The information in the Configuration ROM is needed to identify the node, its capabilities and

which drivers are required.

The base address for the “configuration ROM” for all registers is FFFF F0000000h.

The ConfigRom is divided into the

• Bus info block: providing critical information about the bus-related capabilities,

• Root directory: specifying the rest of the content and organization, such as:

o Node unique ID leaf

o Unit directory and

o Unit dependant info

The base address of the camera control register is calculated as follows based on the camera-

specific base address:

Table 47: Config Rom

Offset 0-7 8-15 16-23 24-31

400h 04 24 45 EE

404h 31 33 39 34

408h

20 00 A0 00

40Ch 00 0A 47 01

Bus info block

410h

00 00 Serial number

414h 00 04 B7 85

418h 03 00 0A 47

41Ch 0C 00 83 C0

420h 8D 00 00 02

Root directory

424h D1

00 00 04

…. ASCII for 1394

…. Bus capabilities

…. Node_Vendor_Id, Chip_id_hi

…. Chip_id_lo

According to IEEE1212, the root

directory may have another length.

The keys (e.g. 8D) point to the offset

factors rather than the offset

(e.g.420h) itself.
