VADJ_FMC Power Rail
The ZCU208 evaluation board implements the ANSI/VITA 57.1 section 5.5.1 IPMI support
functionality. The power control of the VADJ_FMC power rail is managed by the U38 system
controller. This rail powers the FMCP HSPC (J28) VADJ pins, as well as the ZU48DR HP banks 66
and 67. The valid values of the VADJ_FMC rail are 1.2V, 1.5V, and 1.8V.
At power on, the system controller detects if an FMC module is installed on J28:
• If no card is attached to the FMCP connector, the VADJ voltage is set to 1.8V.
• When an FMC card is attached, its IIC EEPROM is read to find a VADJ voltage supported by
both the ZCU208 board and the FMC module, within the available choices of 0.0V, 1.2V, 1.5V,
and 1.8V.
• If no valid information is found in an FMC card IIC EEPROM, the VADJ_FMC rail is set to 0.0V.
The system controller user interface allows the FMC IPMI routine to be overridden and an
explicit value can be set for the VADJ_FMC rail. Override mode is useful for FMC mezzanine
cards that do not contain valid IPMI EPROM data defined by the ANSI/VITA57.1 specification.
ZCU208 MSP430 System Controller
[Figure 2, callout 19]
The ZCU208 board includes an on-board MSP430 (U38) with integrated power advantage
demonstration and system controller firmware. A host PC resident system controller board user
interface is provided on the
query and control of select programmable features such as clocks, FMC functionality, and power
system parameters. The ZCU208 website also includes the ZCU208 System Controller GUI Tutorial
(XTP_TBD) and ZCU208 Software Install and Board Setup Tutorial (XTP_TBD).
These steps briefly summarize these instructions.
