st-gourichon-fid | Hi! Have a working litex/migen/etc environment. Trying to run a design with a RISC on a FOMU. I would be happy starting with *any* base design. But foboot seems tied to vexriscV. Can anyone help? | 11:24 |

_florent_ | st-gourichon-fid: the easiest would probably be to start from the icebreaker target and use the USB-ACM UART (--uart-name=usb_acm) | 12:38 |
st-gourichon-fid | _florent_, thanks, will look into that. | 12:51 |
st-gourichon-fid | _florent_, my hardware is a FOMU. What makes icebreaker.py easier than starting with litex/litex-boards/litex_boards/targets/fomu.py ? | 12:59 |
st-gourichon-fid | to all, following https://github.com/enjoy-digital/litex#user-content-quick-start-guide lacks valentyusb: ./fomy.py "ModuleNotFoundError: No module named 'valentyusb'" | 13:00 |
tpb | Title: GitHub - enjoy-digital/litex: Build your hardware, easily! (at github.com) | 13:00 |
_florent_ | st-gourichon-fid: because the actual Fomu target is a bit outdated i think and probably linked to foboot | 13:00 |
st-gourichon-fid | _florent_, thanks | 13:01 |
_florent_ | i'm trying to create the target for fomu | 13:01 |
st-gourichon-fid | Without your suggestion I would not have considered any other option that fomu.py since my hardware is fomu, for fear of creating incompatibilies. Thanks for the suggestion. | 13:02 |
_florent_ | st-gourichon-fid: this is working: https://gist.github.com/enjoy-digital/82ed88b77ef0b1e3e91b0592e44eaa14 | 14:03 |

_florent_ | ./fomu.py --cpu-type=serv --build --flash | 14:04 |
_florent_ | this is a bit hacky, but should provide you a base | 14:04 |
_florent_ | this will clone ValentyUSB, but you will need to replace IoBuf in it with https://github.com/im-tomu/valentyusb/blob/master/valentyusb/usbcore/io.py#L13-L61 | 14:05 |
