I don't know if dynamic_ss automatically applies to mclk but it seems to, since disabling spread spectrum only for mclk solves your problem. We could suspect that at a given frequency, we have a problem restoring the original message / clock (the higher we get, the harder it is) until at some point it becomes unreliable. I should be able to test it later tonight to confirm if this fixes the bug on my side too.</pre> </div> <hr> You are receiving this mail because: <ul> <li>You are the assignee for the bug.</li> </ul> </body> </html>
