So 9front on pi4 seems pretty stable. But has anyone got audio and wifi working. I recall reading some place that pi hardware developers kind of deviated from convention so its a bit tricky to get some of that stuff working. Perhaps I might also be asking for some sort of guide to read on how to build or deal with making drivers in 9front and some troubleshooting steps to follow. Ponies and Unicorns I want those also, so yea.
yes, miller's version has wifi. i don't remember if anybody did the
work to bring it to 9front, but in any case they didn't finish it ( ==
mainline it).
audio, some people wasted their time with the incomplete audio
solution in the rpi, it but then gave up IIRC.
some people like to add a DAC to the I2C bus, but i consider that also
a waste of time, esp. as long as you can get 1$ USB->audio converters
including shipping from china, the quality is 100% matching the rpi
hardware, and a lot better than most DIY rpi audio add-ons.
as much as i hate USB, for soundcards that's good enough and we
already support it.

i assume you mean adding a DAC to I2S, I2C doesn’t have the bandwidth for quality audio even at 400khz.
using and external dac over I2S can make a very significant (very measurable) difference to the quality of the audio you can extract from a rpi.
the most important part of this is locking the pi’s i2s stream to external crystals, and having quiet power supplies for the dac and any downstream gain stages.
i am afraid $1 chinese usb dacs are a poor second choice.

[-- Attachment #1: Type: text/plain, Size: 1368 bytes --] I don't think Miller's wifi does WPA or any auth. Though I've not ran Miller's pi image in a long time. Miller's wifi driver is also different from 9 front's WiFi driver so it's not a simple port. For good pi audio I use a Dayton USB DAC which outputs pretty clean audio. Unfortunately the pi uses a really crummy SoC as it started life as an EoL'd chip for set-top boxes. That's why it does weird crap like boot from the GPU and lacked proper Ethernet for ages. Even Pi founder Ebbon Upton was unable to grasp why people wanted proper Ethernet as the pi was only ever meant for teaching. It's an educational toy built from a chip scrounged from the cut out bin but everyone seems to want to ignore that part. You get what you pay for. I tend to prefer cheap embedded PC's off eBay or itx Celeron SoC boards if I need a small low power system.

Interesting. Seems like a lot of wasted effort. Unless as you say using pi as a teaching
experiement. So what about hackboard2. Kind of the same specs but Intel. I'm wondering if
it will just boot 9front and work without too much fuss.
well, pi4 on 9front can be used as an efficient terminal. just avoid
the wifi, usb-c, audio, bluetooth :D
as a music player it's also good enough, with a high quality usb soundcard.
rpi4 finally has real 1gbit ethernet. makes it the first viable pi.
of course use cases are extremely limited, but they exist.

Yes it seems really stable as a terminal. It only crashed once while running netsurf
using js mode. To be expected i'm sure. I make the habit of running additional rio when using
netsurf to keep from rebooting. But honestly I don't know what to do with it. I have no need
for GPIO at the moment. I have an extra kbd, mouse, and monitor. So I guess if I ever need a
low cost terminal then I have one to use.

[-- Attachment #1: Type: text/plain, Size: 2456 bytes --] richard miller’s image runs wpa fine - the wpa code is cinap’s ported from 9front. having said this i found a significant latency on wifi on the pi compared to wired ether. it was enough to make 9p feel a bit clunky when used to a file server; so i still use wires. i feel bad i never got to the bottom of the delays. -Steve > On 13 Feb 2022, at 3:41 am, Thaddeus Woskowiak <tswoskowiak@gmail.com> wrote: > > > I'd hate to discourage people from putting in effort but just explaining the reality. > >> On Sat, Feb 12, 2022, 8:17 PM <thinktankworkspaces@gmail.com> wrote: >> Quoth Thaddeus Woskowiak <tswoskowiak@gmail.com>: >> > I don't think Miller's wifi does WPA or any auth.
