Hi Hippo,

my configuration is different. I have:1

MPU HOST (as SPI master) connected with FPGA (here SPI as slave: spi_slave_to_avalon_mm_master_bridge). FPGA is connected as ACTIVE SERIAL and I have to program EPCS with HOST MPU.

This is my problem. Hardware is done and I haven't other possibilities.

For this reason I would to know how EPCS CONTROLLER run and control word bit's meaning.

In my idea I HAVE TO REALIZE (HOST SOFTWARE):

1. use SOF2FLASH to convert .sof into .flash (S-record)

2. write .flash inside HOST flash (by remote control)

3. software to convert .flash to SPI PHYSICAL LAYER for spi_slave_to_avalon_mm_master_bridge with commands for EPCS CONTROLLER

Can You tell me something about point 3?

I have some difficult to find correct use of EPC CONTROLLER.

Bye
