Dave, Thank You for Your help!

To finish for today - maybe You have the formula to calculate configuration time for EP4CGX22 by MAX II from a single quad SPI flash ( N25Q128A13ESE40G ) in PS mode with PFL inside MAX II.

PFL user guide ( p. 50 ) has the formula only for FPP.

Or please tell what to modify in that formula so, that it can be used for PS instead of FPP.

Thank You again!

UPD.

Formula is needed for PS mode with data compression.
