6. FRU Information
The MMC provides 4 kB of non-volatile storage space for FRU information. Some of the data
stored there, such as the Module Current Requirements record or E-Keying information (refer
to AMC.0 specification for details), are mandatory for module functionality in an ATCA/AMC en-
vironment.
Please note that missing FRU information possibly will prevent the AMC module from being ac-
cepted by the carrier controller during the hot swap process, and the module will possibly not
receive payload power.
Full low-level access to read or write a module's FRU information is provided by regular IPMI
FRU device commands. Please be careful when writing FRU information directly using stan-
dard IPMI commands. Damaging the FRU information may lead to a non-working payload.
6.1 FRU Version Identification
The FRU data fields, as defined in the IPMI - Platform Management FRU Information Storage
Definition v1.0, Rev 1.1, are used to record the version of the FRU installed. The revision num-
ber is incremented for each new release of FRU data.
Example of board FRU ID: “STD_R10”
Example of product FRU ID: “STD_R10”
6.2 FRU Data Update
Update of the FRU data can be done via regular IPMI FRU device commands. The correct FRU
data must be prepared at the factory.
Note ...
The FRU data can be read and upgraded via the U-Boot “fru” command. For
further information, refer to the AM4150 U-Boot Bootloader User Guide.
