| + | The FRU Information is used to primarily to provide ‘inventory’ information about the boards that the FRU information device is located on. All FMC mezzanine modules include an EEPROM where this FRU Information, | ||
| + | |||
| + | There are some extensions, or FMC-specific MultiRecords, | ||
| + | |||
| + | In order to better use this data, Analog Devices has written a small utility which dumps the FRU file which can be found on many systems. It also can change the serial number and date (since we use this for production test of ADI's FMC cards). | ||

| + | |||
| + | A tuning (or calibration) parameter for the related board can be written to the EEPROM as seen below. Usually this is integer or floating point values encoded as a raw hex string that is then decoded where it's used such as in IIO Oscilloscope or wherever the parameter needs to be set. | ||
