On digilent nexys video, dual core RV64GC debian ready :
python3 -m litex_boards.targets.digilent_nexys_video --cpu-type=naxriscv --bus-standard axi-lite --with-video-framebuffer --with-coherent-dma --with-sdcard --with-ethernet --xlen=64 --scala-args='rvc=true,rvf=true,rvd=true,alu-count=2,decode-count=2' --with-jtag-tap --sys-clk-freq 100000000 --cpu-count 2 --build --load

That's is weird, seems like the ci doesn't look at litex_setup.py for the install ?

I can see :
Cloning into 'pythondata-cpu-naxriscv'...
Already on 'master'

while litex_setup.py is :
"pythondata-cpu-naxriscv": GitRepo(url="https://github.com/litex-hub/", branch="smp"),

Thanks @Dolu1990! Sorry for the issue with the CI. I'll look at it. Thanks also @cklarhorst for the PR, I'll see if we can try to also use --dev mode for this instread of introducing a new argument.

No worries, thanks ^^

Will, it will likely move on this repo in another folder.
