Sorry if this topic has come up before - I have read numerous threads on this newsgroups regarding this topic, however, I cannot seem to piece together a straight answer. Basically, I would like to boot up my NIOS processor from an EPCS device upon powerup. Since my current board doesn't have any parallel flash, I thought adding an SPI flash onto extra pins could be done instead, provided I wrote some custom code to bootload from that. Then I learnt that their EPCS devices are the same thing as the ST micro Flash devices :) So now, my question is, I have a64Mbit flash device from STMicro. Can I use this too bootload my FPGA and NIOS processor?? I have read some application notes, particularly:
And this seems great and all, however, I can only select EPCS1 and 4 from SOPC builder in the ASMI interface. Any easy way to do this?
