Even if this is an very old message:

I came across this, because I have exactly the same issue: Cyclone V soc with MT25Q

Traces are quite short (D0-D4: 16-20 mm; DCLK 18mm).

On some boards the AS config fails. As soon as I touch the DCLK (when trying to measure where the issue may be) the configuration is successful.

I also assume a timing problem but cannot find any setup or hold timing issues.

How was this problem solved? I would be more than happy to get a hint.

Thank you very much
