This is the first RISCV core I've been able to get up and running without breaking my head. Much appreciation for the SpinalHDL team for the making this work with Qsys and Avalon. :) (Although SpinalHDL itself puzzling still.)

Where should notes and documentation go? (Is there a wiki?) There's a lot of little things I had to figure out. It would be nice to make it easy to post the notes. One ex

I would like to use icestudio in class e.g. to demonstrate the simulation of logic gates. Ultimatively I would like to create logic tables with the students.

I found following two descriptions but - unfortunately - do not speak spanish:

FuseSoC supports use flags, but doesn't document which use flags are actually set. This needs to be documented.

Currently we set:

  • A target use flag target_TARGETNAME, e.g. target_sim if fusesoc is called with --target=sim.
  • A tool use flags tool_TOOLNAME, e.g. tool_verilator if fusesoc is called with --tool=verilator

Support for user-defined use flags is being developed in #26

557 bits isn't too many. Most of these are likely related to the DSP, as 1 DSP is being used:

The README says:

[...] you'll need an SD card image for your DE10 with a valid installation of Cascade. Cascade can generate this image for you automatically [...]

The obvious question is "how". Is there a command that generates the image?

I have a working DE Nano, it has linux running, it is connected through the Ethernet.
Is this image not sufficient, and Cascade should generate
