And also my debug info in attachment

Do you have an hdmi screen plugged in when you started up? I’m sure I see something similar if I don’t provide a screen

Yes hdmi screen is plugged and there is some logging of the processes before main gui appears. But too fast to read all the info. Only if I record it on video with 60fps and will try to slow it down… Or otherwise find the boot log somewhere.

Exactly my solution ! Worked just fine for me.

BTW I can update that the flirc all metal case does something really cool - they have a block that goes all the way to the CPU and the case comes with a heatsink sticker, so the whole case acts as a heatsink. Its outperforms even active cooling solutions. Since the zynthian case is also all-metal, I really suggest V4 to do something similar. It lets you put the CPU at 100% without throttling. cc @jofemodo take a note on this.

Here is someome confirming this (I also tested):

So does Rpi 4 run Zynthian’s software without issues or should I order another 3b instead? I don’t care if it fits the kit enclosure etc.

It works perfectly. Better than ever …

Great! Can’t have too many Zynthians.

Cool, just replaced the Pi3 for a 4 I had laying around, burned a new SD and it just works! Also great I am still mentioned in the config (prototype-kees) :rofl:

I had not used the Zynthian much cause I had many problems with xruns and so… After an hour of playing, no problem anymore. Tnx again for this great project.

Cheers,
Kees

the prototype doesn’t exist anymore? Can we remove the option?

Well, I just replaced the PI, so the wiring stays the same and I was glad to see this scheme still existed. Sometimes I think this setup is not completely stable… So if there is a better way to connect everything, I am open for suggestions. What is (Where can I find) the most stable schematic atm?

I am still using the _w32 which is a child of yours.
Nobody else is using that.
The most stable schematic is not using 23008 when you use encoders :slight_smile:

So I could convert to the all-in-one solution https://github.com/zynthian/zynthian-hw/blob/master/zynthian_allinone/zynthian_allinone.sch.svg ? Right now most of the encoders are directly connected to the PI as I can remember… and I already have a 23017… hmm, 23008 it is



I sometimes wonder if the touchscreen does interfere with the encoderconnections.

BTW, why not sending some basic telemetry data back, so you guys can track the use of peripherals…? And, doesn’t Zynthian have a channel on discord?

We’ve got an irc! Well, I’m in the irc…

Network/Channel?

Swapped the 23008 for a 23017, so the protype-kees can be removed.
