Ok...I checked out the specific commits for the repos mentioned and tried.
But I got the error below.
(libreSOC)varun at varuns5600x:/opt/src/litex/libresoc-litex$ ./fpga.py
--sys-clk-freq=100e6 --fpga=artya7100t --build
Traceback (most recent call last):
File "./fpga.py", line 8, in <module>
import litex_boards.targets.digilent_arty as arty
ModuleNotFoundError: No module named 'litex_boards.targets.digilent_arty'
Digging around found that in the checked out version of the litex_boards
repo, there is no digilent_arty.py but only any arty.py. so changed the line
"import litex_boards.targets.digilent_arty as arty" in fpga.py to "import
litex_boards.targets.arty as arty". The script did went though this time,
but what i noticed is the arty.py seems
to be a very initial implementation of arty 7 support and specifically
lacks arguments like device variants and toolchain. So it's always looking
for vivado. What can be done next..? I guess I cannot simply go to the
latest version of just the litex_boards repo or simply copy the
digilent_arty file over because maybe a lot of other dependencies are also
there. I don't have the experience with git to find out which commit added
proper support for arty7 with the needed arguments and then find other
dependencies for that commit...!!!
