Jrunner + Serial Flash Loader (SFL) + EPCS4 [How to programm EPCS without Quartus II]

Hello, I'd like to adapt Jrunner to work with Serial Flash Loader. I've integrated SFL megafunction into my design and it works great. When I click auto detect in quartus II programmer it detects ...

oposdasdsWell, I used ALTASMI_PARALLEL to get access to my epcs16.

Now I have some strange behaviour and try to describe it.

LPC - my microcontroller (lpc2138).

FPGA - Cyclone II, EP2C8T144

EPCS - EPCS16

1. LPC configures FPGA (via JTAG, with Jrunner port and array of *.rbf data)

2. LPC erases EPCS (uses newly configured FPGA with ALTASMI)

3. LPC writes the same array of *.rbf data to EPCS as to FPGA.

4. LPC checks data from EPCS byte-by-byte.

All seems to be ok, but after I power off the device and tur it on again, EPCS do not configures FPGA.

Can anyone tell me what's the issue?
