        I've been making more recordings, and it I wanted to share one:
      • tpb
        Title: YouTube (at www.youtube.com)
      • Choco31415
        This one is a Microsoft talk on their AI services and research.
      • CarlFK[m]
        No camera?
      • Choco31415
        I didn't think I would be able to this talk.
      • I'm really happy with how audio came out, although I can faintly here some very light audio feedback in the first 10 minutes.
      • CarlFK[m]
        its kinda echoy
      • good audio is hard
      • Choco31415
        The room has a microphone that connects to an audio system.
      • I tried toning it down a little to avoid massive echo... should've done more.
      • *audio system = speakers
      • CarlFK[m]
        how did you get audio?
      • Choco31415
        I connected to the room's PA system.
      • CarlFK[m]
        did the sound coming out of the PA sound like that ?
      • Choco31415
        The echo? Yes. General noise/static? That's the audio capture.
      • CarlFK[m]
        what were you using for audio capture?
      • Choco31415
        Until I get an Atlys, the Behringer U-phoria UM2. (http://www.music-group.com/Categories/Behringer...)

      • Choco31415
        CarlFK, what do you use besides the Opsis/Atlys?
      • CarlFK[m]

        Title: Blackmagic Design: DeckLink Tech Specs (at www.blackmagicdesign.com)
      • CarlFK[m]
        I have 4? cameras that have hdmi out. plugged into that card
      • I have some 6 channel Behringer mixers - which is really just a $150 box to hold a single fader (slider pot instead of a knob)
      • fader is good for adjusting as the person is talking
      • i5 desktops for voctomix
      • a bunch of mic/PA system stuff. im not sure I recommend anyone invest in that if they just want to do recording
      • Choco31415
        Why do you need 6-channel mixers??
      • Wouldn't you need 3 at most? PA, computer, audience?
      • Oh, my last question is, how do you mix audio/video if sources are, say, over 100 meters apart?
      • cr1901_modern
        jimmo: Something I've been wondering; is there any particular reason your improved mimasv2 firmware won't fit with the free C compiler?
      • jimmo
        @cr1901_modern: it's been a while since i tested it, but i was starting to get close to the limit even with the pro compiler
      • theres something like a 2x difference between free and pro
      • cr1901_modern
        I see... I wanted to try to port libmodem _as an experiment_, but I'm not going to "waste" my free trial on it.
      • (not to mention meson doesn't support the PIC compilers afaik)
      • jimmo
        I don't think it's worth spending much more time on the mimas firmware - I'm not sure what gains there are to be made
      • i.e. what would libmodem get you?
      • cr1901_modern
        no gains except to retroactively justify convincing mithro to use my old library I resurrected ;)
      • jimmo
        what it really needs is a better usb stack :)
      • cr1901_modern
        Prob that too, but I'm not great w/ USB
      • The point of libmodem is that it's supposed to run _everywhere_. From your core i7 to your PIC18. But I've not actually been able to test the lower limits of the library (unless MSDOS counts).
      • Maybe I'll port it to msp430 next...
      • jimmo: In any case, this was a q I've been meaning to ask for a while, but just never got around to it
      • Choco31415
        Why not a raspberry pi?
      • cr1901_modern
        Bare metal RPi is an idea...
      • Choco31415: If you're asking about *nix, nominally libmodem just wraps termios
      • Choco31415 has quit

        jimmo: I am not sure if you saw my message above... I am trying linux on arty but it just gets to 'Executing booted program at 0x40000000'
      • you mentioned that before
      • Now I am trying to connect openocd to debug... but didnt get much luck... here is my openocd output+config
      • tpb
        Title: trying litex openocd connect · GitHub (at gist.github.com)
      • jimmo
        yep same as me
      • haven't had a chance to investigate further
      • shorne
        ok, do you know if mithro has gotten further?
      • FYI, I think this was discussed before, but this is how you confirm the binary for openrisc
      • tpb
        Title: openrisc or1k raw binary objdump · GitHub (at gist.github.com)
      • shorne
        Let me confirm the hardware is setup
      • I mean... if it works on opsis and not arty there must be a hard problem i.e. the linux dtb doesnt match arty hardware platform
      • ill look at those and compare... but it would be good to learn how to connect openocd on this board
      • one possible issue?
      • soc_core.py- "uart": 0,
      • but
      • or1klitex.dts interrupts = <2>;
      • but... earlycon doesnt use interrupts I am pretty sure
