Problem with flash programmer

Thanks for your tips

Why did you uncheck 'Program software project into flash memory'? Is there no Nios II program you want to load? If so, you could use the Quartus Programmer instead of the Flash programmer.

I 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.

For only loading a .sof file to the flash, you can go to File-> Convert Programming Files..-> choose e.g. .jic File as programming file type -> choose the right flash device -> click on Flash Loader and choose your FPGA type -> click on SOF Data and choose your .sof-file -> generate. Then in the Quartus Programmer you can choose that .jic File and start programming the Quartus. Every reset of your board the configuration will be loaded from the flash into your FPGA, because you added a Flash Loader.

But i want more than every reset, i want to have my configuration even if I power down the board.

I´ve tried but this error always occure:

Error: Can't recognize silicon ID for device 1

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 :eek: ). Actually, the EPCS16 could be well but he doesn´t want....

BTW, I got that 'There are no Nios II processors available which match the values specified. Please check that your PLD is correctly configured, downloading a new SOF
file if necessary.' message for several reasons already. Once I had some wrong clk assignements in the SOPC Builder, or in the Assignement Editor, or one of my user components have not been programmed well yet. In all that cases I got that message, just because the FPGA configuration was 'bad'. And sometimes it helped just to shut down the Nios IDE and the Quartus, or sometimes it was enough to only close and reopen the Quartus Programmer or once it helped to restart the PC. But the real reason for that message was one of the errors descriped before, what turned out later. Same happened to a colleage. Just to be complete about that error message.

I think my pin assignments are right because when I load my .sof file it works.
