hi,

Quite new to FPGA work, but I am looking to get into openrisc and hopefully run it on a MIMAS2 dev board I have (it runs a Spartan 6).

So first I thought to build the kernel for or1ksim as detailed here:

https://github.com/kdgwill/OR1K/wiki/Build-Linux-Kernel-For-OpenRisc-1000#run-on-or1ksim

and the build seems to work fine, I did

make defconfig
make

exactly as described. And I have a vmlinux image but the file arch/openrisc/or1ksim.cfg is not there. (There are various object files and so on in that part of the tree.)

Any idea why? I guess I need it ...


thanks

Daniel

ok, to answer my own question - seems it is not a file from the build process? I downloaded from here:

https://github.com/openrisc/tutorials/tree/master/or1ksim

and I could simulate hello world - didn't manage to run linux in sim yet ... does it need some sort of loader?

Hi,

I am Rahul. I am also trying to do something similar. If I am guessing correctly, you must be getting 'Segmentation Fault(Core Dump) with your current .cfg file and an empty xterm.

I am saying so because this is the problem I am facing. Even I was not able to find the .cfg file when I built the linux kernel and hence tried with the one from https://github.com/openrisc/tutorials/tree/master/or1ksim.

But as far as I know, the or1ksim.cfg file that we need to use for simulating the linux kernel will be different from this default one, thats why it is not working. But I couldnt find that too.

Sorry that I am not able to provide you with anything substantial. Do let me know if you find some way of making it work.
