Hi Omer Kaan Basakinci ,
Please check your clock:

The example clock:

The example is using the system PLL, but you didn't.
So, select the system PLL clock on your clocks diagram.

Double click the PL2_PFD2_BYPASS:

Select the PLL2 PFD2 output, not the PLL2 bypass clock selector output.
Wish it helps you!
If you still have questions about it, please kindly let me know.
Best Regards,
Kerry
