NIOSII flash downloader probelm

I think Daixiwen has right. For example:

The hello_world_small project for a NIOS2 processor needs approximatly 8 kByte space in flash ram. The epsc4 device has a memory space of 4'194'304 Bits. 4'194'304 / 1024 = 4096 Byte = 4 kByte. You see, you can't store your config file and the program file.

I see my project

myProject.sof size = 1.144KB

hello_world_smal.flash size = 8kB

and myProject.flash size = 906KB

can EPCS4 support these size

I am a new NIOSII designer.

how can I do to solve these problem?can you give me serval ways?thanks

I am also trying to build a own FPGA + NIOS2 project. In my case, I have a 2MB flash memory on board, where I can either store the NIOS2 programm or

the NIOS2 programm and the FPGA config. I think, it's the easiest way.

above is my NIOSII console whole message during the flash programmer

I seems that your project is defined with an EPCS128. Change that setting in Quartus first and recompile your design.

But I still can't see how you are going to fit all this in an EPCS4... You can replace it with a EPCS16, they are pin-to-pin compatible.

I have use assignment setting -->deivce-->device and pin options -->configuations-->configutions devices[EPCS4],and recomile,in quartusII

open niosII ,build all,then use flash programmer,it's strange than EPCS128 also in the console.

where I loss to config?

another, I shall make the footprint to fit the epcs16,I see they are different package,

thank you for helping me:)

That's strange... I don't know where sof2flash gets the information about the size of the EPCS device.

If you open the srec file in an editor you should also be able to find how big is the image to see if it fits in your flash. But from what I see you don't use compression, so it is most probably bigger than what the EPCS can get. Add the --compress flag to the sof2flash command to activate compression.

You shouldn't need to do a different footprint, the EPCS16 can be found in an 8-pin package, just like the EPCS4.
