    Issue resolved, flash problem due to failed/stuck bit in volatile configuration register.

    Solution to accessing Arria 10 ASDATA/DCLK pins, without using Intel IP, during user mode is to use Arria 10 primitives.

Hello,
I overlooked the point that with Arria 10 (also Cyclone 10 CX) AS pins are not dual purpose and can't be regularly accessed in user mode. Thanks for clarifying.

It's however possible to instantiate e.g. ASMI parallel with dedicated ASMI interface. It should allow to read and write AS configuration flash in user mode, isn't it?

Regards,
