View FMC EEPROM Data
All FMC mezzanine cards host an I2C EEPROM that can be read out through the FMC menu. A
hexadecimal display and a formatted version of the FMC EEPROM data are provided through the
FMC menu. The VITA 57.1 standard identifies the data fields of the intelligent platform
management interface (IPMI) specification used for the FMC EEPROM.
Select the FMC interface tab with the target FMC card, and then select the EEPROM tab and
click Get EEPROM Data. A window appears displaying the contents of the EEPROM. The
example shown in the following figure is for an XM107 card connected to JA3.
Set FMC VADJ
Each FMC interface connects to a set of I/O banks on the RFSoC. The RFSoC bank voltage is
connected to VADJ on the FMC interface to allow the FMC card to track the bank voltage that is
connected to it. The system controller can change the bank voltage that is connected to each
FMC interface. JA3 is connected to VCCO_HP bank I/O pins and JA4 is connected to VCCO_HD
bank I/O pins.
Select the FMC interface tab with the target FMC card. Select the Set VCC_HP or Set VCC_HD
tab, depending on the interface. Click the button with the desired bank voltage (see the following
figure).
IMPORTANT! Changing the bank voltage affects all banks connected to that bank voltage, not just the FMC
interface. Confirm that any other I/Os being used on the ZCU1285 board are compatible with the new bank
voltage.
Note: Power cycling ZCU1285 reverts all bank voltage changes back to the default voltage levels.
