i'm now using the microtronx nios2linux-1.4 to run linux on nios.

when i build the project, it says that it needs a flash to upload the kernel to, but we don't have a flash in our board, the result is that i cann't go on with it.

is flash absolutely necessarily?if not, what should i do?

i'm a newer in nios,can anybody give me advice?thanks in advance!

Thank u for your reply!

When i build the project, it says that it needs a flash to upload the kernel to, if there isn&#39;t any flash, the NIOS II IDE wann&#39;t let you go on.

So could you please tell me how could i download the system to sdram indirectily in detail?

So if the IDE wants it, why don&#39;t you offere one?

Even it is not on your board, you can try to add one. Or just edit your PTF-File.

The flash is needed for the root file system with romfs, if you use the Microtronix&#39;s kit.

You must find other root file system, since you don&#39;t have flash.

You may follow the nios wiki to use initramfs for root fs. It might save a lot of troubles.
