I have a 2 GByte one on order for delivery tomorrow. The next challenge will be to get piCore on it.

Do you know which kernel versions are known to work with it?

N.B. Those 2 HDMI are micro sized sockets.

I have just downloaded the latest Raspbian Lite that supports it and it reports
pi@raspberrypi:/ $ uname -a

It will certainly need a whole lot mode drivers.

Looking in the boot partition there are 3 kernel
kernel.img - Linux version 4.19.50+
kernel7l.img - Linux version 4.19.50-v7l+
kernel7.img - Linux version 4.19.50-v7+

Yuck, I was afraid of that.......that means another 10mb or so on the boot partition. And a whole set of module extensions to manage.
Here is the new defconfig they are using. https://github.com/raspberrypi/linux/blob/rpi-4.19.y/arch/arm/configs/bcm2711_defconfig
-
Yes a pain.
If I get a chance I will try and get piCore booting on it.
They are clearly selling well, CPC had 3000 in stock at 8:00am - sold out by lunchtime.
The spec looks good, it looks as if they have sorted out the I/O bottleneck of Pi3, I have an Odroid as a NAS and the performance is great, but this Pi should compete.
Any chance of you Busybox config? - Thanks
Tim.

I had to order mine from Canakit in Canada.....all the USA distributors were out by the time I could get online >:(.
Ya, on busybox, I got sidetracked.

My RPi4 will arrive this week.

Bela,
It is good to have you around. I hope everything is well with you.
I hope that you do not mind that I have tried to get piCore development going again.
Tim.

Hi Tim
thanks for asking. Everything fine, just had hacktic times with my main job not leaving time for piCore. Now it is a bit better. Just started to make a new version last week and I have seen RPI4 is coming. One side it is great, on the other hand it must be handled is causing some delay again.
If we can work in a team including Paul and anyone else willing to join we can make it live again, but too much for one person.
Regards,
Béla

Bela,
That sound great, i fully agree that it is all too much for 1 person to do. We need to sort out how to organize things.
On the Pi4 I have it booting into piCore
tc@box:~$ uname -a
Linux box 4.19.56-piCore-v7l #1 SMP Tue Jun 25 19:10:37 BST 2019 armv7l GNU/Linux
tc@box:~$ cat /sys/firmware/devicetree/base/model
Raspberry Pi 4 Model B Rev 1.1
tc@box:~$
I have other pressing work to do so can't get back to it until the weekend
Tim.

Got my Pi4B (4GB RAM) yesterday. 'Raspian Buster' appears to be not finished, still 32bit ..
What I thought was an error turned out to be " in the mainline Linux kernel device tree files - all Pis report as being BCM2835, whether they actually have BCM2835, BCM2836, BCM2837, or BCM2838/BCM2711 in."https://github.com/raspberrypi/linux/blob/rpi-4.19.y/arch/arm/boot/dts/bcm283x.dtsi#L19 (https://github.com/raspberrypi/linux/blob/rpi-4.19.y/arch/arm/boot/dts/bcm283x.dtsi#L19)

RPI is not planning to release a 64 bit version, and will not until there is a valid reason too. https://www.raspberrypi.org/blog/raspberry-pi-4-on-sale-now-from-35/#comment-1510286
And all pis have reported as BCM2835 for sometime, this is intentional as well.
-
Just because RPF have not done a 64bit version does not mean it is impossible
I use Gentoo64.
The Pi4B1 is cheaper than the 4B4 but 1GB is small for a dual screen OS.
Unless there is nice small OS ;)
Any speed penalty between 32 and 64bit is now less important as the 4 is faster in everything.
With the dual screens that makes it a reasonable box for Desktop development.
But probably best to get the 4B4 when compiling things like the kernel.
-
My RPi4 just arrived, show is starting :)
-
Just back in stock at The PiHut, so mine's on order now, should get it next week, waited for the 4GB version, didn't see any point in just getting a 2GB version. ;)
Will be following your progress. :)

Clues for a PiCore64?
https://www.raspberrypi.org/forums/viewtopic.php?f=63&t=244478
PI4 is smoking fast even on untuned Raspbian.
Er, smoking just mean now usable as Desktop :)

Personally I don't see any advantage of 64bit on the Pi, but I have just installed Openwrt on a Pi3 and to my surprise it reports
root@OpenWrt:~# uname -a
Linux OpenWrt 4.9.152 #0 SMP Wed Jan 30 12:21:02 2019 aarch64 GNU/Linux
-
Did not know OpenWRT was 64bit on Pi3.
Thanks for that, now that the Pi4's are out I need to do something with my 3's.
Battlemesh is interesting.
Going to be interesting to see how long it takes for a Pi4 2711/A72 version.
Some big software apps like databases prefer 64bit.
The big software houses are dropping 32bit support.
The thing with PiCore is it works really well on the smaller Pi's and probably 32bit is ok.
Not going to see massive databases running on a Zero W?
Why go to all that pain when spending a few more 10x dollars gets you a Pi4?
A Pi4 with 6 Uart connected Zeros could make a small multiuser system.
A few of those and donated screens and a classroom could be setup?

Hello gavinmc42,
if you have one spare RPi3, why not using it for a "Pi-hole" (https://pi-hole.net/ (https://pi-hole.net/)).
IMHO the best network-wide ad-blocker you can find.
Mine runs on a an iMX53 QSB with custom compiled kernel
under Debian Strech without any problems.

Found the 64 bit Alpine Linux very fast on RPi 3B . The 64bit WoA (Windows 10 pro-1803) on the same Pi3B is a bit slow but the WsL is usable.
Hope the TinyCore for Pi4B is gradually nearing the release date...

Anyone put pi-hole on PiCore?
Raspbian Lite is too big for me, I would prefer a nice small PiCore version.
But is the Ethernet fast enough on a Pi3?
-
I've glanced at the install script several times.....doesn't look like it would be all that bad to do. Updates and persistent/log data is probably the most difficult to deal with.
I think Ethernet speed is relative, but isn't pihole just a glorified DNS server. Not all your traffic is going through the device.
-
I vote gavinmc42 gets pihole going on piCore. :D
I was looking at it last week because I seem to be getting bombarded with advertisements!
BTW: I really like the writing style of the pihole scripts.
-
Hi,
I didn't want to hijack this thread with quite different topic. Maybe we can
open a separate thread to share ideas.
Therefore only some additional thoughts:
@Paul:
You are right. Pihole is only responsible to resolve (or block) URL requests.
The remaining traffic is untouched.
@Greg:
That's exact why I installed it about half a year ago. Up to 40% of URL requests
are blocked, because they are directed to advertisement or tracking systems.
The current 'blacklist' has about 140,000 (sic!) entries at the time of writing this.

I will be getting a Pi4B4 for development, things like PiCore kernel compiling etc.
But I found the Fifth Browser not too bad back in version 9?
Is that similar ad blocking?
-
Uh oh, the usb-c connector is missing some resistors ...
https://www.theregister.co.uk/2019/07/10/pi_4_usb_c/
Apparently this might confuse *some* power adapters with e-marked cabling as being an audio device. I suppose a fix is already in order ...
-
I'm using the old 2.5amp supply with adapter.
Don't need the extra power for USB HD yet.
Power supply is not the same as charger.
And USB-C PS/Chargers might do bad stuff.
Why fix something that might not work on all those third party PS/Chargers.
Get the official 3amp one(when available) and support the RPF?
Or recall all Pi4's?
Those who can afford a Macbook don't have any money spare for the Official supply?
But yep rev 5.0 of the PCB is in the works?
-
Any Updates on a Pi 4 Kernel?
-
...that means another 10mb or so on the boot partition....
Not exactly, since the Pi 4 uses a complete own kernel there is a good option to minimize the boot partition size. Just by spliting the whole thing in 2 different images. Images 1 Pi 1 - Pi 3, Image 2 only Pi 4 kernel.
This should safe us some space.

The released the first 64bit working Pi Linux
https://www.balena.io/blog/balena-releases-first-fully-functional-64-bit-os-for-the-raspberry-pi-4/
Its balena, a distro specificly for containers.
