<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?

<_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)
<st-gourichon-fid> _florent_, thanks, will look into that.
<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 ?
<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'"
<tpb> Title: GitHub - enjoy-digital/litex: Build your hardware, easily! (at github.com)
<_florent_> st-gourichon-fid: because the actual Fomu target is a bit outdated i think and probably linked to foboot
<st-gourichon-fid> _florent_, thanks
<_florent_> i'm trying to create the target for fomu
<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.
<_florent_> st-gourichon-fid: this is working: https://gist.github.com/enjoy-digital/82ed88b77ef0b1e3e91b0592e44eaa14
<tpb> Title: Fomu · GitHub (at gist.github.com)
<_florent_> ./fomu.py --cpu-type=serv --build --flash
<_florent_> this is a bit hacky, but should provide you a base
<_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
<tpb> Title: valentyusb/io.py at master · im-tomu/valentyusb · GitHub (at github.com)
<_florent_> Here the image if you want to test (with bitstream + bios)

<somlo> _florent_: did you ever have a DTS blob for litesdcard (litex_mmc) in its previous incarnation? Or is that a question for antmicro?

<mescobar> the CSR programmers API https://github.com/enjoy-digital/litex/wiki/CSR-Bus
<tpb> Title: CSR Bus · enjoy-digital/litex Wiki · GitHub (at github.com)
<mescobar> If I had a application that manipulates the CSRs of a given peripheral, where would I put the application c-code in order to get cross compiled & included into the rootfs.cpio
