JIC Vs sof file cofiguration for SGX IV and EPCS128, PCIe

hello all,

I am having a strange peoblem. I configured everything so that there will be a PCIe link between the FPGA and a switch. When I use *.sof everything works perfect, when I use *.JIC with EPCS128 there is no conection. I checked the following:

1. voltages in Power up by recounfiguring after all the power Stabilized. no change

2. reseting the switch a minute after the FPGA was configured. no change

3. configuring PCI transmition. it works.

So it is not voltages, nor the switch ( it works with sof), not timing from configure of FPGA PCIe and switch and the EPCS works fine coz it configures something else.

Plz do help, thanks.
