Does the 'remote update' block actually work on Cyclone V?

I'm trying to get the 'remote update' (ie the reload the fpga from EPCQ) block to work on a cyclone V using quartos 14.1. I've managed to expose the epcq pins to 'user' logic and can successful...

Just for memo. In case someone have the same problem.

For CYCLONE V GX

1.If the nSTATUS pin was clamped up to VCC by external MCU, you would expect to see remote update not working, just hang up/freeze.

2.If you use non-official EPCQ such as N25Q256A, for your AS configuration device, and forget to pull up pin 3(RSTn), your FPGA will not function properly, even not be accessible by JTAG some times.

3.If you select QUAD rather than STANDARD in ALTERA SERIAL FLASH CONTROLLER with those non-official EPCQs, you will not be able to program anything into it by NIOS ii software, but .JIC will be OK, and remote update will be functional.

MT25QL512ABB has different command set with EPCQ512, but working well expect QUAD programming by NIOSii.

N25Q256A has the same command set with EPCQ256 but, still not working in QUAD programming by NIOSii.
