Hello,

I builded the project on Vivado 2014.2 for VC707 as described in article:

     ADI Reference Designs HDL User Guide [Analog Devices Wiki]

I compiled the no-OS source code on SDK for VC707 as described in article:

     AD-FMCOMMS1-EBZ Quick Start Guide on Xilinx FPGA Boards Without OS [Analog Devices Wiki]

I change the XCOMM_DefaultInit initialization structure in main.c:

     defInit = {FMC_HPC, XILINX_VC707, ...

I get a messages on the COM-port terminal:

     Running XCOMM Test Program

     Initializing XCOMM I2C...

     XCOMM Init I2C Failed!

Because the FPGA firmware initializes I2C the VC707 through the FMC1 HPC J35 connector and the FMCOMMS1 attached to the FMC2 HPC J37 connector


I change the XCOMM_DefaultInit initialization structure in main.c:

     defInit = {FMC_LPC, XILINX_VC707, ...

And the initialization is successful.

I get a messages on the COM-port terminal:
