git and osh links updated

fix is very simple, I can make a photo demonstrating

Mine will be the 191021 version I think. With the added resistors missing some routing. Thanks

#211

@tehn yes please pics for a fix.
Also, is there any beta image? I have all the components and RPI4 ready to build it, but no image to mount…

#212

Just realized I have some boards made on 20191007. Should I thrash them or can they be fixed as well?

#213

We don’t have a published beta image at the moment, there’s still a bit of work to do, a list of which can be found here https://github.com/simonvanderveldt/norns-image/milestone/1
(the project is currently still under my name and not the monome org because we’re still testing out this approach).

The code in the linked repo currently works on the Raspberry Pi 3 and norns, there is no Raspberry Pi 4 support in there yet.
But @ngwese has a Raspberry Pi4 and has been working on adding support for it which AFAIK is pretty much working. He can tell you more about that than I can though :slight_smile:
Note that we’re all quiet busy with multiple/different things, so it might take a bit of time till it’s finished.

both previous boards will very likely work perfectly well without any modifications— part of the reason we didn’t notice the error in the first place.

for 20191007 you need to add three resistors tied to 3v3. i can make a diagram for this.

there are actually 3 missing traces on 191021. just use a tiny wire to bridge the solder pads. they may even be close enough for a solder blob.

newest/proper version is 191106. i’m finalizing the order of SMD-populated boards now.

osh link fixed on top post with newest.

#215

@tehn, I am building it right now, a diagram for 20191007 would be handy :wink:

#216

we’re working on a buildroot-based image, but in the meantime i’m going to post a raspbian-based version.

i just need to pull the kernel/libs/configs onto our existing build. hoping to get this done tomorrow.

#217

for 191007, 10k resistors between these three points

thanks a lot, I was starting to scratch my head…“where are those R2, R3 and R4???” :slight_smile:

#219

currently struggling with freecad to cut out a 1590bbs hammond enclosure. freecad is not very user-friendly :confused:

Board is built. i miss a couple of 47u but I guess I can test it withouth them, hopefully

Today I woke up and the norns.img was created. (it took hours…code and instructions taken from here: https://github.com/simonvanderveldt/norns-image)

I flashed it using balena, but the RPI3 doesn’t even boot, I even tested it with a standard HDMI cable connected to a monitor and no shield. The same RPI works and boots normally using a Raspbian image…

Is the norns.img file enough for it to boot? should I copy something else?

#221

Oh and BTW, the silkscreen for the 2x40 RPI connector is probably on the wrong side of the board, at least on my 190909 board.
It seems it’s still in the 191106 board:
(it’s pure joy when you realize that while soldering your last pins…) :slight_smile::cold_face:

#222

That’s actually a frustratingly hard and time-consuming fix.

The ‘part’ in EAGLE - the electronics CAD software that generates the board - that represents the header is, in fact, a part that represents an entire mobile B Pi - so it includes both the header and the three mounting holes and markers for the pi’s outline. Flipping that piece of silkscreen would involve… redesigning and replacing the part in its entirety.

If I were to suggest a fix, it would be adding text saying “place header on underside” along the top of that outline.

#223

Is there any chance you could adjust the default batch size on your Octopart BOM? It’s currently set to 500, and when I click the “add everything to my cart” shortcut… I get a $5000 Mouser cart…

will fix. also I made a non-smd bom

#226

hoping to get a modded norns img posted today

updated for qty 1. (also added OLED and OLED header)

also here’s a no-smd version: https://octopart.com/bom-tool/Jor87JZR

also! SMD populated boards ordered. i’ll be able to start shipping them first week december. pricing TBD, but they will be very cheap.

seems to be mostly working, still need to check audio in/out becasue I din’t have those 47uF capacitors…however I got some audio using headphones :slight_smile: software-wise everything seems OK

For anyone following along/that also wants to try this see https://github.com/simonvanderveldt/norns-image/issues/32

The built image was meant for norns not for the Raspberry :slight_smile:

Nice! That’s good to hear/see :slight_smile:

P.S. The image is still using an older norns version so for example there’s no crow support at the moment
