Has anyone has succesfully compiled Nios2-linux?

Altera_Forum · ‎09-28-2011

Hi everyone,

I am working on Nios2-linux with MMU for Stratix 2- EP2S60F672C3N. The linux-2.6 is using kernel 3.1.0-rc7. It uses Device Tree. I followed http://www.alterawiki.com/wiki/devicetree. Everything else is set to default. Got error during make. :cry:. So, if anyone have successfully compiled the nios2-linux with mmu and downloaded it to FPGA board, could you please help me. There is no proper tutorial available. Thank you.

It would be much more clear if You'd use the pastebin.com and post the log with the error. Remember to post all the settings You've used.

Thank you.

Check your command line args, you may not tell the kernel where the ramdisk is, so the kernel can not find the init binary.
