TSB43AB22A: TSB43AB22A GUID Setting

Hi,

The ROM is optional, it provides a hardware mechanism to load the global unique identification (GUID) and miscellaneous implementation specific data to the 1394 host controller.

I believe the Window still provides 1394 Legacy Driver, but you may need additional SW on top of the driver to support PC to PC communication. 

Thanks

David

Hi

Are there any functions that cannot be used without setting the GUID in ROM?
In that case, do I need to make any settings on the OS?
What kind of policy is used to set the GUID in IEEE1394? (Example: Port , device unit)

Regards

Hi,

Please see this presentation for information on the GUID in the IEEE 1394, http://www.1394ta.org/developers/seminars/guid.pdf.

You can also refer to both the OHCI controller and 1394 spec.

Thanks

Every device on the bus needs a unique GUID.

In practice, the only case where a link-layer controller does not have its own EEPROM is when it is integrated on a motherboard, and the BIOS initializes it with a GUID stored in the main BIOS EEPROM.

There is no standardized way to initialize the GUID from software; neither the Windows nor the Linux drivers do this.
