Add Custom SRAM to NIOS

Hi to all,

does anybody know how to add a custom sram to my Nios II system?

I mean that I instantiate a Tristate Avalon Slave in SOPC builder that is compliant with my sram but subsequently I cannot select this memory inside "Nios IDE" on page "System Library" where I usually select "Program memory (.text)", ".rodata", "stack", "heap", etc...

Thank you

    Thanks to all.

    User Viper21 from NiosForum figured out how to fix this problem.

    After creating a component, located and open up the .tcl file.

    Find the line "isMemoryDevice” and change the value from "false" to "true".

    Many thanks to him.

    However, I am astonished that there is not a check about it in SOPC builder...
