  • Add cfg(has_virtual_leds) to fix kasli_soc-demo compiling error due to PR #244.

    • Tested with nix build .#kasli_soc-demo-jtag -L and built successfully.

  • Need #252 to add "has_virtual_leds" to rustc-cfg file

IIRC misoc does that by default for all CSR cores and those lines are not necessary?

You may want to check migen-axi as well - it might not share this code with misoc.

Difference between artiq and artiq-zynq

  • In artiq repo, the rust-cfg is generated by calling f.write(cpu_interface.get_rust_cfg(soc.get_csr_regions(), soc.get_constants())) in the misoc/integration/build.py.

    • get_rust_cfg analyze the content of soc.get_csr_regions() and soc.get_constants() to carefully obtain the useful string and output it to the rust-cfg file

  • While in artiq-zynq, the write_rustc_cfg_file(soc, filename) is called to generated rust-cfg in src/gateware/kasli_soc.py

    • It copies the content of soc.rustc_cfg = dict() directly to rust-cfg file

rust cfg difference if using get_rust_cfg

  • The write_rustc_cfg_file(soc, filename) was modified to follow get_rust_cfg
  • Then run python src/gateware/kasli_soc.py -c build/rustc-cfg kasli-soc-satellite.json

Yeah we should try to avoid divergence with misoc.
