Still waiting for my board too.  For $15, a nice little piece of hardware.

For the config.txt, it follows the [PI02] directive.  But for all intents and purposes, a pi3 to the kernel.   The wifi needs different firmware BRCM43436 .....which I'll update shortly.   The interesting thing with that, the new firmware was added to the rpi packaging 13 months ago.  At some point in the future, the board will get a different wifi chip that will use BRCM43436s.

According to RPi, the latest RPiOS images work with this board, those images are 5.10.17 kernels.  So things might be promising the current piCore release.

Latest piCore 13.0.x ccomes with 5.10.16 kernel. It is 8 months old, I will release 13.1.0 with an up to date kernel.

Could you have a look at this:
Code: [Select]
$ dmesg | grep cert
[    3.498402] Loading compiled-in X.509 certificates
[  403.494066] cfg80211: Loading compiled-in X.509 certificates for regulatory database
[  403.558074] [<805e3eb0>] (x509_check_for_self_signed) from [<805e32b4>] (x509_cert_parse+0x16c/0x1c8)
[  403.558090] [<805e3148>] (x509_cert_parse) from [<805e3bf0>] (x509_key_preparse+0x20/0x1a0)
[  403.559333] cfg80211: Problem loading in-kernel X.509 certificate (-22)

..something connected with compiling natively and missing a cert/crypto module?

Yes bmarkus,

........the community's are reporting slightly better performance from the "Pi zero 2 W" with overclock.........than a "pi 3+".......

https://www.youtube.com/watch?v=5RB29g18m-I

Also people may not know about the free "Debian build" of a tool called "Puffin browser." which will run in Rasbian and other Linux's builds  (likely even picore)  for these boards.

Puffin works perfect on these boards..........it gives excellent web performance with as many as 8 HEAVY web tabs open in a single browser session. 

Such tabs as Facebook, Ebay etc......... and also fluid 1080p video from "youtube" in the web browser......... on a 1.4ghz overclock board.

(it leaves Chromium standing......even when Chromium is ran on some regular Laptop)

People need to also remember that many applications can be run in a web browser
from the cloud.  Making these small computers extremely useful.  "Audiotool"


There are tons of free advanced web apps that run in the browser.... ready to go.........







........these tiny computers have very good software ecosystems
out there.
https://mxlinux.org/blog/mx-fluxbox-raspberry-pi-ragout-now-final/

There are full custom  Android 10's for the Pi's .......ready to go
https://konstakang.com/devices/rpi3/

Then such things as "Cameyo" free droid app can give you limitless ways to run any Msoft apps you choose.... from your Pi.  (in the cloud)

.....And you can also run the free "AURORA" droid app...... a "play store clone"....... for thousands of free droid apps to your Pi......

There are many free custom 64 bit Linux builds for these boards. @https://mxlinux.org/blog/mx-fluxbox-raspberry-pi-ragout-now-final/

The portability and replacement costs means the board could be a desirable PC platform .........sporting almost zero power consumption, and negligible buying  cost..... for a desktop PC.



........i am finding some commercial high end music apps that are built for "Pi's"
such as  "Reaper" and "Waveform FREE"  .......giving excellent performance on an overclocked board. 

https://www.tracktion.com/products/waveform-free

These DAW's can also easily take many free ARM vst's .....that's  "VST & VSTi plug ins" compiled for ARM...... as chains.........

( there are many free ARM plug ins already existing [VST's].........  (compiled for Arm).....)
(professional level)


A "pro production suite" can be achieved on a shoe string with this board
Training academy's could be built etc......

......there are also commercial graphics tools compiled for "Pi's"....



i mean as a general purpose all round computer it works.......... it can work real good via "browser web apps" from your DSL........

it can also be used as a professional platform for productivity. ( Titles exist for it)

There are also free custom "Blue Ray player media centers" for it.........so it doubles up  it's usage as a home media centers

https://osmc.tv

........it saves people the need to buy home satellite boxes and expensive smart TV's

why bother with all the above. I think it's the "replace-ability" of these tiny computers and convenience.......(almost throw away in nature......yet useful)

i mean many forum members use the boards for embedded projects, but it's many other things too.......(just flicking in & out microSD cards)

Hi bmarkus,

Got mine too a few days ago and (as you will soon find out) confirm that current 13.0.3 won't boot (stuck at rainbow screen).

Waiting for the update....

Thanks !
