I am very sorry because I think that I was wrong in my thread.

I have compiled several designs and tested them with the TSE. At least, the one which was working (with internal FIFO of course) was the one where I took the clock from PIN AF 14 (50MHz) and feed it to a PLL and finally to the pcs_ref. The one with the hsmc_ref_clk can probe the driver but transmission is not working (which seems to be the problem you mention here). With all these files on my hard drive, I properly mixed some files and that was leading me to this error.

So, as far as I understand: The clock is only working if you not assign it in Quartus? If you have found a solution, I would be interested, too. Obviously I need to configure the SI5338Q anyway.
