@yongshiwo, is this still relevant? Did you try with a more recent version?

I find your use case pretty exciting! While I check the design... would you mind providing some more context? - Is the challenge public? It'd be nice to have some...

@rob-ng15 maybe you can update or recreate #310?

My bad! :wink:

IANAL, but since none of Apache 2.0 or BSD-3-Clause are viral, you can mix them in a project and distribute them together, without any issue. See https://softwareengineering.stackexchange.com/questions/40561/is-bsd-license-compatible-with-apache.

Hi @dalnefre! Yes, it is still desirable. Have a look at greatscottgadgets/luna#80. Any other design would also be acceptable. However, dealing with USB in HDL is non-trivial, and meeting timing...

Kate assigned herself a few days ago: https://github.com/greatscottgadgets/luna/pull/80. We should have something to play with soonish, as the idea is to pre-generate a verilog black box from LUNA's `usb/acm_serial` example.

It seems that sources are written in C: https://github.com/im-tomu/micropython/tree/fomu/ports/fomu
