Hi Kattice

I am trying to use a custom component to connect to the MM side of pcie. I can use either Gen 1 or Gen 2, just need to get it working in SOPC. But i am facing the issue i mentioned. I tried ST version to make sure pcie is working fine. I am using the 100 Mhz clock and generating the 50Mhz(reconfig_clk) and 125Mhz(fixed_clk) using a PLL. Also the inverse locked output from the pll is used as offset_cancellation_reset for altgx_reconfig .

Hi nekojiru,

In SOPC builder I am able to select the Gen2 version. Do you mean it will still not work. I will try with the Gen1 version and see whether i can get the pcie to work

Thanks a lot for the reply.

Regards

Hari
