This just in…

heads up: SuperCollider 3.10.1 successfully built for RaspberryPi…
…and the still-in-development Ableton Link code, also working on the Pi!

if anyone is using my push 2 branch, then the new Norns 2.0 version is on the new branch tb2.0.
(new branch name as I might be adding some other devices, the previous push2 branch will be retired)

note: please read the 2.0 beta caveats on the main norns 2.0 beta thread

also, Ive made crib notes of what I did to update from 1.x, if anyone needs them.

main change, if your building on something other than a norns 2.0 image, then you will need to install boost

sudo apt-get install  libboost1.62-dev
./waf configure

@TheTechnobear Did you also need to install libjack-jackd2-dev ?

I have that in my notes from awhile back, but can’t remember if that was really necessary

Otherwise can report that Norns 2 beta has been working well for me on RasPi

#549

What kernel are you using atm?

#550

@okyeron , no , probably because my nornsPI image is very close to norns,
so what I do is use the update.tgz, unpack it, and adapt it to my setup - this only takes a few minutes. so its likely the update had jackd2-dev installed. (this was the case with boost on my nornsPI)

the other possibility, is I also have Orac (inc PD) / MEC (my software) and EigenD, running on my Norns PI - so Ive likely installed it as part of that.
(but I don’t use boost for other software, hence why I noticed it needed to be installed on other platforms)

@reijo, good question … its the latest Raspbian kernel, (not the norns kernel build)
I cannot remember if i kept with my own build of it, or reverted it back to stock.
I did play with quite a lot of kernels, including RT pre-empts, but they didn’t provide much better performance when I did tests with norns, so possibly i reverted, but i might not :wink:
Then I upgraded to a rPI3B+ when it was released, and thats has a bit of ‘headroom’ over the CM3 of the Norn, so performance was never an issue.

I guess now some are starting to upgrade their Norns to CM3+, which is same cpu as rPI3B+, we may start to see some scripts that push it a little more :wink: …
on the flip side 2.0 should offer a little better load distribution over cores, so should be less of an issue.

would love to see your crib notes TB have installed boost and would like to upgrade rather than build norns from scratch again. :grinning:

#552

here you go :

as I said, mostly its just take the update.zip and then edit it according to you needs :slight_smile:

#553

my initial tests show no real CPU improvement between the CM3 and CM3+. i was under the impression (from the specs given for the CM3+) that the main improvement was heat management and huge flash. did i misunderstand this?

sorry, my mistake …
the rPI3b to rPI3b+ went from 1.2ghz to 1.4ghz, I assumed , incorrectly the CM3, to CM3+ did the same processor bump…
but your right, CM3+ stayed at 1.2ghz … perhaps they thought the heat management was more important for the CM3 line?!

its no big deal really, that 200mhz bump is pretty modest really - as i implied above, it just feels like a bit more ‘headroom’ rather than any real extra processing power.

Linux norns 4.14.52-v7+ #1123 (although I can’t remember now if this is a fresh recompile of everything or my working setup from norns 1.0). I’ve got to work on making a new image and install instructions for my DAC board soon.

While updating won’t let me run /.update.sh saying permission denied for some reason?

#557

should be : ./update.sh
its it update.sh that can be run, or something its running?
(Id need to see the error message really)

if its just update.sh , then you could do
. ./update.sh
or
chmod +x ./update.sh

(im assuming your are in the update directory (i.e the one where update.sh is sitting)

#558

chmod +x ./update.sh this makes it run but i am getting these permission errors when running ./start.sh in /norns
192.168.1.12 ~/norns $ ./stop.sh

#559

which user are you running this as? this all should be setup and run as ‘we’

did you have all this working prior to the ‘upgrade’ , as none of this should have changed during this process…

#560

yes still ‘we’ and was fully working before.:thinking:

have been using an external editor instead of nano could this be it?

yes it was. thanks all good now :smile:

Any ideas on where I f-ed up?

#562

maybe check norns-init.service, norns-jack.service and norns-maiden.service to see if they’re throwing any more human readable errors

decided to do a fresh recompile before continuing.

following errors are present:

maiden seems to be working.

looks like it might be an issue with jack not being set up properly(have a Complete Audio 6 connected, but haven’t done the setup for it yet). Maybe I just answered my own question…

thanks!

#564

Yeah - you gotta get the sound card configured first - otherwise jack will not start properly on launch.
