FPGA configure problem

[Altera_Forum]

I'm a jackeroo of FPGA 

there's a problem for me. In configuration handbook, ps mode can use JTAG to configure the Configuration Device, now I want to use MCU to configure Configuration Device and then the Configuration Device to configure FPGA. Dose it a feasible mode？ Please help me!Thanks!

What's your configuration device? In my opinion, direct PS FPGA configuration from the MCU, or an AS configuration device updatable from an MCU are versatile variants with minimum part count.

I'm sorry I can't understand your means, could you please explain more specific? I use EPCS64 as serial configuration devices.during configuration, what's the file formats?could you please recommend me some documents?

[Altera_Forum]

EPCS64 is only using as configuration mode. Configuration schemes are discussed in the respective FPGA hardwore handbook and the Altera configuration handbook. 

 The AS configuration device can be programmed from a MCU by directly interfacing CS, SCK, DI and DO, also FPGA nCE must be driven high to disable FPGA access to the device. Quartus *.rbf files can be directly programmed to the AS memory, the data bit order has to be reversed related to the SPI standard.

Thanks so much!Hope to keep in touch!

Add questions: 

You said the Quartus*.rbf file can programmes to the AS device, but how to generate this file? I know Quartus can generate *.pof file SRunner reads the *.rpd file and programs the data to the EPCS.Can you explain this? I realy don't know how to convert file formats? Please tell me more specific! Thanks!

*.rbf generation can be selected in the device options. Also the Convert Programming File tool from Quartus File Menu can do.
