Monome Grid & Bela

Hi all

Are there any Monome users here? I'm trying to get my grid128 interfacing with libpd, but I'm having trouble. I've already posted on the lines forum so hopefully will get some info from there too

I got the monome libraries libmonome and serialosc installed, but kindof stuck here as I can't start running serialosc?

I've also read a bunch about the usb hotplugging issues on the bela currently and am wondering what the best practices are for USB detection after boot? I have a powered hub with the monome going in... it flashes lights as if initializing but lsusb never detects anything new. Also booting with the monome plugged in results in the bela hanging and never initializing. Possibly because it's trying to boot off of whatever is connected through USB? Unsure

Any help is appreciated, thanks

(k, replied a bit on lines, but better keeping it here)

the only issue I had with hot plugging, was if NO other device was plugged into the hub, the hub doesn't come out of power saving mode correctly... and subsequently, throws all sorts of weird errors.

so plug anything (usb drive, midi controller) into the hub, then boot bela,
then try plugging the monome once the boot is complete.

(actually, I think its also ok, if you plug in the hub with the device (e.g. monome), after its booted, but cant remember for certain... so best to try this, once we have more info)

it would be good if you could post what your seeing from the console logs (dmesg), something should appear there even if the device is not recognised.

as also mentioned on lines, what Id also try, is running on the current BBB distro, and seeing if it works there... as its got a newer kernel.
(what I do , is run Xenomai/bela off the sdcard, but have the current bbb distro in emmc... useful for testing things )

It would not try to boot off "anything connected through the USB". I never once had a problem with a device that was plugged in at boot. If this "bela hanging at boot with one USB device connected" thing happened only once, then you may have hit a peculiar BBB bug (which we are trying to fix) which occasionally prevents the device from booting at all for random reasons (actually correlated to the serial port). Simple fix should be: power off and back on again. So please try that 2 or 3 times and if it still hangs, then try the following:
- connect the usb hub and connect something to the usb hub (e.g.: a usb drive, a mouse, a keyboard, anything)
- run lsusb to make sure the device shows up
- connect the monome
- run lsusb to make sure it shows up

Thanks guys. I got the bela detecting the monome now

Getting segmentation faults when trying to run serialoscd with current kernel (assuming this is something you had as well @thetechnobear ?) Also I'll stop tagging you in both forums haha sorry

Going to try updating to current bbb distro in emmc

I've written a script that I've been using a couple times lately that automates everything there is to do to setup a monome on a fresh bela image, it's here: bela-setup-monome.sh. It can also serve as instructions to do it manually, it's just a list of commands without any logic.

It requires a working connection to the internet from the bela, and git, and it does the following:
- Install various build dependencies via apt
- Clone libmonome from github, compile it and install it globally
- Clone serialosc from github, compile it and install it globally
- Write a systemd service file to start serialoscd on boot, and restart it in case of failure
- Put the file at the right location, put the right permissions
- Run ldconfig so that the libs are found properly and things run smoothly

I've been using it with the latest image and it's been working great, but more or less the same instructions, without the systemd part worked on a rather old image that I had running before updating (can't remember how old).

Let me know if anybody runs into issues.

Hello, I'm a bit confused, how do I properly run this bela-setup-monome script? Where do I place the file? I am using Mac. Thanks!

giuliomoro

That has to be executed on Bela itself, and Bela has to be connected to the internet for it to work. You may be able to enable internet sharing from your Mac through the "usual" macos internet sharing procedure.

ndivuyo

So to execute on the Bela itself, I execute it in the BELABOOT with terminal or upload it in the IDE or do some other method with terminal? Sorry, I've been trying to look around how to install these libraries and for some reason not understanding where I run the code.. I tried to execute it from the Bela-Master Script directory but I just got errors.. I think it was not correct method?

to follow up on this, the right procedure to execute that file should be:

connect Bela to the internet
then run the following commands in a terminal

# get on the board (may prompt for verification, type `yes` and enter)
ssh root@bela.local 
# download the setup script to the board
wget https://raw.githubusercontent.com/padenot/bela-utils/master/bela-setup-monome.sh
# execute it
bash -ex ./bela-setup-monome.sh
# start the service [it will start automatically upon reboot]
systemctl start serialoscd

In the future, if you want to see the log of the serialoscd service you can run

journalctl -f -n 50 -u serialoscd

ndivuyo

Yikes, so after I executed this bela-setup-monome.sh script from the Bela-master Script directory, I can no longer open the IDE in my browser. I even ran the update_board script and restart my computer, and still the IDE doesn't load Any ideas?

The SSD card did not slip out and I tried following the instructions here, but I can't even get a successful ping or loading of any of those addresses:

giuliomoro

oh that escalated quickly, and in an unexpected way. What do you get when you run ifconfig in your terminal?

this is Bela. So the board is booting and coming up, however it does not have the appropriate IP. This IP may be because you have enabled internet sharing. Do you have it enabled?

Can you try to run

ssh root@bela.local

?
Does it get you on to the board? If it doesn't, you could try to follow these instructions to properly share the network https://github.com/BelaPlatform/Bela/wiki/Connecting-Bela-to-wifi#sharing-wifi-over-usb-with-bela however it is mentioned here that an extra step may be needed (possibly dependent on the version of macos).
Ultimately the easiest way of getting a Bela connected to the internet would be to connect an ethernet cable into a home router: it is painless and it just works.

ndivuyo

giuliomoro ssh root@bela.local

When I run this it just hangs. I will look into the other recommendations tomorrow, it is a bit late now here. But the IDE was working fine before I ran the monome sh script.

Thanks for all the help!!

giuliomoro

as mentioned, the first step is

giuliomoro connect Bela to the internet

Now, to do that ... see this:

if this is not an option, then see this:

ndivuyo IDE was working fine before I ran the monome sh script.

yeah, but there is nothing in there that would affect it when running the script on your computer - which I understand is what you did...

[you may have to undo the internet sharing to be able to go back on the board at all, although I'd be curious if you could try ssh root@192.168.7.2 (assuming you are not on Catalina and/or have a v0.3.8 Bela image, otherwise try ssh root@192.168.6.2 instead)]

ndivuyo

Hey so I tried "ssh root@192.168.7.2" and it also just would hang. But I stopped internet sharing ad the IDE works again! I will now attempt to execute the monome setup file the correct way as you suggested a couple of posts back, however, since I am not sharing internet now it may not work?

ndivuyo

So when I run the line:
"wget https://raw.githubusercontent.com/padenot/bela-utils/master/bela-setup-monome.sh"

I get this error:

--2020-07-15 08:48:49-- https://raw.githubusercontent.com/padenot/bela-utils/master/bela-setup-monome.sh
Resolving raw.githubusercontent.com (raw.githubusercontent.com)... failed: Temporary failure in name resolution.
wget: unable to resolve host address 'raw.githubusercontent.com'

I tried both with and without internet sharing the Bela and the result is the same.

Any ideas? Thanks!

ndivuyo

Oh sorry about that, I assumed my internet sharing was working before but was wrong!

So I followed the steps on the second option since I don't have an ethernet cable or easy access to a router. And that was successful I think because I now can ping 8.8.8.8.

However, when I run "wget https://raw.githubusercontent.com/padenot/bela-utils/master/bela-setup-monome.sh" I get these errors now:

giuliomoro

that is probably because the date on your board is behind. It should updated in a few minutes after the board is connected to the internet, so chances are if you were to try again now it would work. If it keeps failing, load up the Bela IDE and that should also set the date on the board, at which point you should be able to re-run the line successfully.
