Honored Contributor
Honored Contributori have only some vhdl code, i have written this code in quartus, but in the help they say to use flash programmer for a non-volatile configuration. so i jus use a hello_world project to have a project but i don´t cate about what this program does. i just want to load my .sof file.
If you only have some VHDL code, there is no need to add a Nios cpu in SOPC Builder, you can delete it, if it's already there or at least, if you need it as avalon master, use the smallest Nios cpu ('e'). This will reduce your configuration size, too. Without Nios cpu, you don't need any Nios program either. but i want more than every reset, i want to have my configuration even if i power down the board. Sorry, I wrote it imprecise, if you program the flash with a .jic-file, of course you will also have the configuration present after power down, it will be reloaded automatically from flash with the next power up. i don´t know what that is. i am forced to use epcs64 for flash device because for the others configuration he told me there is not enough memory ( my .sof file is 1.886 kb and the .jic file 8.193 kb ). actually, the epcs16 could be well but he doesn´t want.... In 'Convert Programming Files...' you could go to 'Options' and click 'Compression Mode', but I've never tried, maybe first read some documentation about that. error: can't recognize silicon id for device 1 I saw that error already, but sorry, I don't remember what was wrong that time. Maybe somebody else can answer this or you can find an answer in this forum. But first you could try the things described, maybe then this error is cleared. i think my pin assignments are right because when i load my .sof file it works. I also think so, it was just a general comment to that error message.
