Hi Gopal, Your XSG core config parameters look fine to me. I do not understand how the adc0_clk clock frequency should affect the sys_clk-generating MMCM in any way. Can you send me the full output log of your compile? Also, can you send me the XPS_ROACH2_base/system.mhs file from your design directory?
As for the fixed point toolbox, I see that commits 1b13e3d, 617ba13, and b3d63ce remove the fi dependence from the FFT blocks. This was after the most recent time I merged with ska-sa and so the sma-wideband FFT still depends on the fixed-point toolbox. You can try cherry-picking those commits to remove the dependence for now. I have tried this but I have not tested it. Unfortunately merging the two forks at this point would require quite a bit of careful thought since there are many conflicts that would need to be worked out. I will give this a shot since this needed to be done eventually.
