- How is the microcontroller connected to the FPGA? Can you drive DCLK, DATA0, nCONFIG signals of the FPGA from the MCU?
--- Quote End ---
No the MCU is not connected to the flash memory; it is connected to FPGA by i/O ports.

- How are the FPGA MSEL pins connected?
--- Quote End ---
MSEL0 pulled-down to gnd; MSEL1 pulled-up to VCC; MSEL2 pulled-down to GND. But this configuration could be changed mounting or not specific resistor.

A simple way to accomplish this is to use the Passive Serial config mode and the SPI interface of the MCU (or bit-bang it if the MCU does not have SPI).

The MCU has SPI interface also connected to FPGA. Can you explain me better how use Passive Serial config?
Is it possible to make the MCU write register in FPGA and then make FPGA write flash memory? How the data could be written?
What is the better way?
