About EPPROM of AD-FMCOMMS2-EB

Question asked by BobbyChang on Apr 10, 2015
Latest reply on Apr 13, 2015 by rgetz

While applying the fmcomms2 RFDB with AD9361 IC to Synopsys HAPS 70 FPGA platform with Xilinx Virtex®-7 FPGAs, the RFDB is not power-on correctly and the main 1.3 V supply bias is not output.
After a serial of check, It is found that there is something mismatch between the content of on-board EEPRON(U201) and  HAPS platform.
There are some questions as following

:

(a) What is the ddefault VADJ setting saved in the EPPROM? The Virtex®-7 FPGA supports I/O data with swing less tham 1.8 V.
(b) In ADI Wiki(http://wiki.analog.com/resources/tools-software/linux-software/fru_dump), a FMC FRU EPPROM Utility is referred. Where can this utility be downloaded? Is windows version avaiable?
(c) Can the FMC FRU EPPROM Utility work with fmcomms2 RFDB? and How to setup?
(d) Can the  VADJ value in EPPROM be modified to 1.8 V for test?

Thank you for help.
