--csr-json csr.json doesn't produce the output file #1296

I installed litex as instructed especially installing the Risc-V toolchain with

./litex_setup.py --gcc=riscv

Also litex_sim --cpu-type=vexriscv is starting up a simulated litex Bios.

Though following the wiki at Generate Renode Simulation

python3 litex-boards/litex_boards/targets/digilent_arty.py --cpu-type vexriscv --with-ethernet --csr-json csr.json

Runs through without flagging any error, but the csr.json file is not generated.

Where do I find the csr.json which I need to generate a .repl for renode?

adding --build --no-compile seemes to do it.

Hi @mzau,

thanks for reporting. This is indeed a side-effect of disabling the build by default (which also had other side-effect), that I also encountered a few hours ago. I'll try to improve this.

Hi,

Is there any progress on this issue? I'm also encountering the same error when generating the Litex.resc and litex.repl files for Renode. I'm getting the "config_cpu_count" error, which indicates that this attribute is not correctly defined in the csr.json file. It seems that the "--build-no-compile" command is not working correctly.
