nios2 linux run on ram, of course.

but you have to load the object code of linux to ram and then run it.

during development, you can use usb jtag cable to do the download to sdram without writing the flash. the command is "nios2-download -g vmlinux (or zImage)" , it is faster than flash programmer. but you have to download sof with quartusII before nios2-download.

when you want to build a product, you need to write your sof and linux to flash (cfi or epcs), so it don&#39;t need a jtag cable connected to PC.

You should really follow the buildroot guide.

if you can read Chinese, you can read the translated,
