Has anyone already managed to run RNBO on a Raspberry Pi 5? I got mine today and notices that it won't boot on the image provided by Cycling74. I seems to need debian bookworm.

I don't have a pi-5 yet, still waiting for my pre-order.. I'd be the one setting up the image for bookwork so, that'll have to wait until I have hardware to test with.

In the mean time, if you want, you can build/install the runner yourself. Here is how I set it up on bullseye:

@Alex: I didn't managed to build it myself. But adding the repo manually:

curl https://raw.githubusercontent.com/Cycling74/rnbo.oscquery.runner/main/config/apt-cycling74-pubkey.asc | gpg --dearmor | sudo dd status=none of=/usr/share/keyrings/apt-cycling74-pubkey.gpg

echo "deb [signed-by=/usr/share/keyrings/apt-cycling74-pubkey.gpg] https://c74-apt.nyc3.digitaloceanspaces.com bullseye main extra" | sudo dd status=none of=/etc/apt/sources.list.d/cycling74.list

sudo apt install -y rnbooscquery rnbo-runner-panel

after removing pulseaudio and installing jack following the link you sent did manage to get it to run and to compile a sample patcher.

Only have a pisound interface right now here - which does not work yet on the Pi5 so i can't test further.

In any case, there's no rush (besides my curiosity :) ). I can wait until you get your Pi5.

Oh cool to hear that you're able to run via the bullseye repo!!

Initially i made just a very quick test. It ran and could compile a simple test patch. Later I realised that the audio engine couldn't be started if didi not set it to the dummy interface. I guess that might be to the configuration of Jack maybe. Jack remains to be very confusing to me.... never really got my head around it.....

From my part no.... I stopped fiddling  around. Couldn't get the Jack Audio part solved. I am now waiting for Alex to prepare a new RaspiPi Image.

I still don't have the hardware. I missed the boat on an order over the christmas/new years holiday but i have made a pre order that says it should be here mid January.. so, hopefully soon after that I can get something together.

Thank you Alex! Looking very much forward .

Any news on this? Just got a raspberry pi 5, installed the c74 image and I'm not being able to get it recognized by rnbo in the export tab. Not sure if it's the fact that its not yet supported or if I'm doing something wrong.

The Raspi 5 requires a current Rasperry Pi OS version (based on debían bookworm). It won't boot on the bullseye image from C74. You can try to install the RNBO runner and Jack manually on a Bookworm (32-bit!) Raspi OS. I could get to show up, but didn't mange to get the audio engine to run.

my pi 5 has been delayed further but I do plan to work on it as soon as it arrives.. supposedly shipping at the end of Jan.

Hey, I'm also keen on getting my rnbo patches to work on pi5. Is there a way I can get started?

You can try to install it manually  on bookworm from the repos. I described the steps earlier in this thread 

I followed the steps you provided and installed rnbooscquery and rnbo-runner-panel but the rnbo export target does not seem to recognize the pi. 

Here is the Export log from RNBO after attempting to export to target using IP address of my pi,

I've followed the steps mentioned above and got the pi5 on RNBO but I'm not able to compile with my hifiberry set as the interface. This might be a specific issue so I've created a new thread for this. 

https://cycling74.com/forums/rnbo-issues-with-pi-5-jackd2-hifiberry-adc-dac-pro

I feel like I'm very close to setting everything up right, any suggestions would be highly appreciated. 

I came to the exact same point as you did, and couldn't figure out the Jack configuration either. I am using the Pisound. So it seems to something not necessarily related to the sound interface but the jack/RNBO.

If some has an idea I am very interested as well.

Hopefully the Pi5 situation i  the US is getting better soon, so Alex can prepare a ready to run image!

I got my pi-5 at the end of the week last week and hope to get something together with it this week.

I suspect that the pi-5 OS and jackd running on it are 64-bit executables but the binary that we've provided for the runner is 32-bit and so it is incompatible.

Ohhhh that’s great news! Thanks a lot for everything, Alex.

yeahhh :) I'll install it and will give feedback very soon!

the image installs fine and recognises my Pisound. In a very fast test yesterday I noticed that MIDI input from the Pisound doesn't seem to be recognised (at least MIDI data are not processed properly, like notes not playing etc.), USB MIDI seems to work fine. I'll need a couple of days ore to test ore in depth.

Hi JAN M, Did you manage to get audio in/out from the pisound working? I've managed to set up the pi5 for rnbo and updated config to get hifiberry on the list but I'm getting the same error as before with the audio at export. 

Basically, I'm in the same spot as before, 

I haven't tested audio input yet. Output seems to work fine. There have been some changes on how I2S is handled on the Raspi 5. It may be related to this.  Pisound requires Kernel version >= 

Maybe there are similar issues with the hifiberry

I'm curious if you've done the overlay configuration that they recommend?

I found this blog entry that may be of use:

https://www.hifiberry.com/blog/dac-pro-dac2-pro-dac-adc-pro-on-pi5/

https://community.blokas.io/t/pisound-for-raspberry-pi-5/4733/46

I've followed all the steps on the main datasheet as well as the general hifiberry setup page. 

here's what my config.txt looks like at the moment.

I've also made the changes mentioned in the blog you shared, but still facing the same issue. 

We've seen issues with the hifiberry products and jack. You could try connecting to jack directly from your pi to debug, assuming the device shows up as 

If that doesn't work, something is wrong with the hifiberry configuration and I'd suggest you follow up with their support. If you get some insights, we'd love to hear about them.

You can discover the alsa name by looking at the output of 

You're right, jack is not initializing the driver for some reason 

YASH, try running that as the "pi" user instead of "root"

I think it is an issue with their driver.

We've had success adding "-P" to the commandline arguments to only enable playback (output).. but our runner doesn't support that option yet, it really shouldn't need to if the driver correctly identifies its i/o I don't think.

Yes, I am actually part of the discussion in that thread (yunn02 is I )

Pi5 is a completely new platform so it's normal that it takes time to smooth everything out. I am sure we'll get there eventually!

Thanks Alex, I've started a new discussion on the HifiBerry Forum, 

https://support.hifiberry.com/hc/en-us/requests/24861?page=1

Hi! I mounted the image and I am now able to get it recognized by rnbo. I ran into the same response error as Yash ("cannot activate audio") when trying to export once connected to my audio interface (Motu Ultralite Mk-5). I find it strange as the interface worked fine on the normal rpi OS. When I try playing audio from the internet I'm not getting sound either so I assume it has something to do with jack. Any ideas or pointers?

The solution that worked for me was here:

https://support.hifiberry.com/hc/en-us/community/posts/15584862199581

TLDR: The dtoverlay config needs to be changed to the following (from recommended)

force_eeprom_read=0
dtoverlay=
dtparam=audio=on
dtoverlay=hifiberry-digi,slave

The "slave" part isn't actually supposed to work, but for whatever reason it actually made it functional. I have not tried it on the just released image yet, but it worked when I got rnbo running on raspbian (on a pi5 8gb).

Would I need to change anything considering I'm not using hifiberry?

I'm curious if you can get jack running directly via ssh?

so, for instance, i have a `USB` named interface so I run

if this fails, I'd love to see what the output is.

Hey Drew Bach, I'm curious how your specified config changes worked. In the HifiBerry doc, they had mentioned removing the line, 

is there a way to get into jacks config or preferences? 

I managed to get jack running through ssh by setting the buffer size to 128. (suggested here for realtime, 

https://linuxmusicians.com/viewtopic.php?t=14672#:~:text=For%20%22low%2Dlatency%22%20type%20operation%20%2Dp%20will%20need%20to%20be%20at%20256%20(already%20a%20bit%20slow)%20or%20lower

Although RNBO is giving me the same error even after setting period frames to 128 in target settings. 

Also an update from my side regarding the Pisound:  Blokas  has release arm64 packages of their installer/driver scripts a few days ago.

After running those DIN MIDI is recognised fine by RNBO.

Thanks for letting us know, that is great news!

Just to get a little be more info, if you're running jack in a terminal window, can you open another one and restart the rnbo runner, then try exporting from max?

if that works, I'm curious if you can remove those 

 entries from your jack command and try the whole thing again?

jackd -d alsa -d hw:sndrpihifiberry -p 128 -r 48000 -n 2

If one is looking for reliable live performance with RNBO controlling audio/midi on Raspberry Pi, then stick with Model 4?

Until there is an official RP5 image released and tested I’d say yes. RP5 may still involve some fiddling.

Many thanks for the quick and effective response!  Since I still have drawer full of unused 4s, might as well get things prototyped.

I've got sound and real-time control through the OSC interface! 

Although removing the i/o tags from the jack command gives me the same error: 

ALSA: cannot set period size to 128 frames for capture

Is there a way to include these commands in boot, so that I wouldn't have to do it every time? 

Either way, thank you so much for your help! I can finally continue my project with RNBO! 

You could look into creating a systemd service that starts jack up with your custom configuration before the RNBO runner. RNBO would then no longer control the jack settings, it would simply connect to your pre-configured jack instance.

Perfect, I'll do that! Thank you for your prompt responses and support throughout this!

Beginning the process of installing and testing RNBO on the same audio interface and a newly arrived RPi 5/8Gb

I will try the image linked above and add my feedback.

EDIT: The disk image (1.2.4) worked great -- I can see and edit the export target params.  HOWEVER: I get a compiler error:

Starting Code Generation
Generating Objects
Compiling Patcher
Printing CPP Code
Sending config
Sending code
Compiling
rnbo cmd response error: {"code":2,"message":"compile failed with status: 1"}

I gather that this indicates that the version of RNBO on my computer doesn't match the rnboosc version on my pi.

@Alex: Is there an updated disk image, or is there a way for me to update the version I have installed?  I have reasonable *nix chops.

Thanks to everyone supporting RNBO!  I love the platform.

I've just built a .deb for RNBO 1.2.5 that you can use

wget https://assets.cycling74.com/rnbo/pi-images/rnbooscquery_1.2.5.deb
sudo dpkg -i rnbooscquery_1.2.5.deb
sudo reboot

If you don't have wget installed you can get it via:

For future ref, if you want to build on your own, check: 

I have some feedback on my experiences so far testing RNBO on the Raspberry 5. I use a Pisound as my audio interface.

- when using the DIN MIDI in I get hanging MIDI notes when playing a bit faster.  It doesn't seem to happen with USB MIDI keyboards. 

- When connecting/disconnecting a USB MIDI keyboard on a running Pi5 the web interface stops responding and doesn't reload anymore.

Furthermore the pi gets stuck in shutdown/reboot for maybe 2 minutes or so, when a USB device has been changed

The first issue may be pisound specific I'll try to see if I can get more info from BLOKAS. 

PS: Do you know if there will be an official RNBO Rp5 image release in the foreseeable future, or probably you need to wait until the platform matures a bit more...

I hope to get pi5 "officially" supported with a 64-bit image by our next minor release, 1.3.

This plug/unplug issue is concerning, I'll make a ticket for that.

The DIN MIDI issue is also a bummer, I'm curious to hear if BLOKAS comes up with a solution. Since the runner uses jack for midi, you might verify that some other jack program can also trigger the same behavior.

@alex, just a heads up: I am in contact with BLOAKS to figure out if the hanging MIDI notes are related to the pisound or not. Will let you know if I know something.

@Alex: It seems that the pisound I was using was on an old firmware version. I just updated it and in first tests the hanging midi note problem seems to have disappeared. 

Guys any news with "officially" supported rpi image?

I just created a new image based on the latest official raspberry pi 32-bit bookworm "lite" download.

This should support pi 3, 4, 5 and zero 2w. 

https://assets.cycling74.com/rnbo/pi-images/raspios-bookworm-lite-32bit-rnbooscquery_1.2.6.dmg.zip

I still hope to get a 64-bit image together eventually.

If you give this a go, please let me know how it works out.

Hi Alex, I received a forum email notification about a post from you, mentioning bookworm 32 bit image for testing. The post doesn't appear here, but the download link works. It is  ready for testing, or did you delete the post for some reason?

I jumped the gun, posted something then redacted it.. should have a 32-bit bookworm image available for the next release though but I don't yet have a timeline.
