Hello all,

I am a master student and I am new to fusesoc.

I have booted Linux on DE0-Nano FPGA by following sources:

https://github.com/olofk/fusesoc
https://github.com/openrisc/orpsoc-cores
https://github.com/openrisc/linux
http://cear.ufpb.br/~isaac/site/tutoriais/openrisc (Tutorial)

But the default core is "mor1kx", which is defined in orpsoc_defines.v.

Now I am wondering whether I can use OR1200 to boot Linux.

So I commented out "`define MOR1KX" in orpsoc_defines.v and run Quartus II programmer again.

But there is no message from SecureCRT window this time.

Should I do something to make it work like mor1kx?

Thanks!

Hi,

You should stick to mor1kx. Mor1kx is a modern implementation of openrisc architecture.
Plus, mor1kx is maintained.
