CPU looks different from the 2, will we be able to run Slackware?

Soon or later... I hope yes, I've ordered last night :-P

The SOC is a lot different and the core is a 64bit ARMv8 cortex-A53. I've not yet played with any 64 bit arm machines, nor have I documented myself so I don't know if 64 bit ARM supports running 32bit code like x86_64 or if it's a pure 64bit architecture like IA64. If it's a pure 64bit architecture we're stuck until we get an arm64 slackware port, else we can probably use the 32bit slackwarearm userland.

I did a quick search and according to Linaro "ARM’s new 64-bit architecture is fully compatible with its 32-bit architecture. This means that if the processor is running on a 64-bit enabled operating system, the processor is able to run unmodified ARMv7 32-bit binaries" ... my bet is that the RPi3 can tun the slackwarearm userland provided you fetch a kernel that will boot.

It does support 32-bit executables and kernel. According to Eben Upton, the RPi3 retains "complete compatibility with Raspberry Pi 1 and 2".

But crunching 64 bits at a time will make this one even faster than the Raspberry Pi 2.

It is still with the broadcom chipset though. I'm growing tired of dealing with this proprietary nonsense.
Alternatively I'm waiting for the pine64 boards to ship. This board costs less and is more open.

I have been quickly browsing Pine64 website (admittedly too quickly!

) and didn't find much in terms of openness. Found some references to DRM, secure boot, "can run Netflix", OpenGL ES, hardware support for H265, H264...

Have they claimed somewhere that all this comes Open Source, with no proprietary blob, no proprietary/closed firmware to handle the secure boot and trusted zone stuff?

I have also found some info regarding partial open-sourcing and/or reverse engineering of Allwinner VPU drivers but don't know if it applies also to the more recent Allwinner64 bit SOCs.

Any shed of light or pointer would be much appreciated!

TIA

Got mine today, will be setting it up soon

Well, no go off the fatdog RP2 installer or the boot MicroSD that works on one of my other RP2's. It boots fine with rasbian

ok, followed this
http://docs.slackware.com/howtos:har...rm:raspberrypi

and have it booting the miniroot.

Had to plug into my TV since I haven't had a monitor in years. It wouldn't accept the root password listed with the latest minirootfs so I had to blank it out. Then plugged into the network and couldn't login and remembered ssh doesn't allow blank passwords by anymore. So brought it back down to the TV and booted again and set a password and logged out and back in to test it then back upstairs to a network jack and ssh still won't let me login. Now I remember it won't allow root by default so have to bring it back down and create another account or change the default.

Ok, so finally up and running, although just minirootfs

I got a RPi 3 for a friend of mine a couple of days ago and he got it running with Raspbian for RPi2 32bit.
Then he told me yesterday he got Debian for ARM64 DVDs to play with.

I presume future SlackwareARM will also feature a 32 & 64 builds ?

enine · 03-13-2016, 03:28 PM

One step forward, two back.
I had written the rasbain image to my microsd to test the Pi3 and it only made a 1.2G partition so that filled up real quick. I tried to dd it to a USB flash drive and boot from it and it just panics then. Tried again by creating my own partition and then extracting the Slackware miniroot and it just panics as well. Seems there is something missing.
Got it going again, must have been a pebcak error.

Thanks, that might save me some time since that is typically something I could do :-P

One noteworthy thing about Raspberry PI 3 on-board WiFi:

Wireless network must use WPA + AES.
If it uses WPA + AES/TKIP or WPA + TKIP, it is ignored by hardware.
See https://en.wikipedia.org/wiki/Tempor...tocol#Security

This is the first I heard of where such a feature is expressely disabled in hardware.

So set your AP to use AES and not AES/TKIP

enine · 03-14-2016, 08:02 PM

I'm running now. Didn't mess with the wifi yet, but I have Slackwarearm-current, mariadb, apache, php and, owncloud running.

andrixnet · 03-16-2016, 03:33 AM

A decent overview of the RPi3 here: http://www.instructables.com/id/The-...Look/?ALLSTEPS

enine · 03-16-2016, 08:42 PM

The 3 defiantly runs and feel faster than the 2. even just ssh'ed in and doing things its faster.

Tonus · 03-17-2016, 05:11 AM

Hi all,

I finally managed to install slackwarearm headless, thanks to fatdog.eu... and last Raspbian image :-)

I've still wondering how to finish the full install : I've mirrored the current repo but doubt of what is the right path to install-new

Shall I blacklist kernel packages ? I will avoid kde packages for sure but is there anything else I should pay attention to ?

I can't even determine if the uboot warnings are valid for the RPi3...

Any help would be much apreciated !

Regards
