Hi Olof,

Thanks a lot for your reply , I understand better now.
I got the linux working on ork1sim by not using the copied source( earlier
I was copying the linux folder which did'nt work out).
I  tried to build FPGA image and I have following errors, hoping you can
help out:

1.  When I ran - *~/work/openrisc/fusesoc$ fusesoc init  *after the warning
messages I get

*Directory to use for orpsoc-cores [/home/vidya/.local/share/orpsoc-cores]
: orpsoc-cores*
     So I gave the input as orpsoc-cores which created and downloaded the
cores in fusesoc directory.

Now as you mentioned when I create new directory for build and run the
build command:


*~/work/openrisc$ cd
build_fusesoc_DE0Nano/~/work/openrisc/build_fusesoc_DE0Nano$ fusesoc build
de0_nano * I get the error:



*WARN:  Failed to register cores root 'orpsoc-cores is not a
directory'ERROR: Can't find system 'de0_nano'*
I then tried to build the image inside fusesoc directory as I thought the
cores are present in it and I get the following error:
~/work/openrisc/fusesoc$ fusesoc build de0_nano

There are two causes that I can figure out :
1. Maybe because I have different versions of Python?
2. or Maybe because I'm working behind a proxy?or something else.

Can you please tell me what could be the solution?

2. Also I want to run a simple C program on the linux on or1ksim. How can I
do it? I saw using toolchain installed I can cross compile the code and
then run the code in linux. To port the code in the linux I have to use gdb
server ? Do you have any updated links/steps to do this?

Thanks &Regards,
Vidya
