Is there any step by step instructions how to change the CM3?
I was wondering how hard it is, mainly interested because I use Norns mainly with Glut…

It’s easy, you have to remove the screws from the bottom with a Phillips screwdriver, remove the encoder caps and the encoder nuts that are recessed beneath them (you will need some long pliers or something like that) and then the screws on the pcb. Then you slide carefully the pcb out and you will see that the CM3 is attached in the same way computer RAM is. You replace it and screw everything together (except the bottom, you’ll need it open to put Norns in disk mode and then back in Run mode after you flashed it) and it’s done.

For those that want to try on a CM3+: I don’t think the image currently expands to the full disk-size/space available on the CM3+.

ah, ok, then I will wait, although the description by @AlessandroBonino sounds easy enough to do…

Oops, I didn’t check. Now I have and can confirm.

to expand disk

sudo raspi-config

The wifi auto-connect is a nice touch. Selected it this morning and it quickly connected.

Thanks. Can you share step by step instructions on the final step here, where you flash the CM3?

It’s in the first post. I followed those directions exactly and it worked.

ugh - CM3+ seems to be out of stock everywhere in the UK - would have been an ideal time to upgrade the whole lot in one go…

Holy smokes, the image is now downloading 500 times faster this morning, hitting a peak of 27 MB/s. Alright, time to upgrade…

Ta.

I just added a single sentence at the bottom of the “scripts/projects” section:

SuperCollider engines can also go anywhere inside a project folder.

Thanks @tehn, I have now 27Gb free in my Norns. :heart:

The only thing I’ve found is that now it can’t sleep (it happened only once in ten times, I guess). It stays on the “sleep.” page, I can go back but the “sleep?” confirmation does not appear, it goes directly to the “sleep.” page but it doesn’t actually go to sleep. I tried the reset item in the menu but the only thing it does is making the “sleep?” page reappear but it still doesn’t go to sleep. I can’t find a log, maybe it would help.

Suggestion unrelated to OP: The “RESET” label could be renamed “RESET AUDIO” to best reflect its purpose (and to match docs).

#55

Well, it was Reset Audio before, but since now it displays the boot animation I assumed that now it’s a complete soft reboot.

I did the CM3+ upgrade and flashing was successful, but now I am having WIFI issues. both CONNECT and ADD just lead to a blank screen.

edit: Wifi started working after I expanded the filesystem via raspi-config. Not sure why, but not complaining :smiley:

Hmm thought norns was now using a 128 sample buffer, with 2 buffers on output side? In that case, synth-control latency due to audio blocks should be 4ms+/- 1.3ms (Max jitter being half a block, average latency being a block and a half)

Now, worrying about the best part of 2ms really would be dumb - except that latency usually stacks, and worst case jitter adds linearly. I would guess block size is probably not the latency jitter bottleneck of norns…

This would be a perfect candidate for a video, and I will offer a subscription to my fabulous (free) zine to the enterprising individual who makes one. Also anyone else. But especially the person who makes the video.

Just ran into this…

SLEEP doesn’t seem to work when Playfair is open. If I switch to Awake, SLEEP seems to work fine. Perhaps Playfair is too groovy to sleep?

EDIT: File browser request… can the sample browser remember the last open folder? It’s really slow loading up a specific folder of drum hits into Playfair.
