piCore 17 Beta Releases

Hi meo

... So the only thing I have to do to be able to use for example pragtical is to, from the prompt, issue the command tce-load -i Xorg-3d.tcz followed by startx at the prompt. ...

Why don't you add  Xorg-3d.tcz  to your  onboot.lst  file and just
let it start automatically?

Hello Rich!

I did just that some time ago but that led to some kind of conflict that made me have to install everything from the ground. Now i have one in my RPi 5 to which I have to add the 99-vc4.conf file to make it work. That I don't have to do in RPi 4. So it's just one thing to do to prepare the environment anyway (something that I can remember and not read from some notation).

Regards,
meo

We need to make an adjustment to a startup script to add 99-vc4.conf for RPi5 with Xorg-3d.

I can't help feeling that, whilst adding 99-vc4.conf solves the problem, it is not the actual problem.

The current startup script is in xorg-server because 99-vc4.conf is needed for RPi3 and below for x to work at all, but it is perhaps more logical in the case of RPi5 for a startup script to be added to Xorg-3d?

Hi Juanito!

That sounds good. It would be easier to use the RPi 5. I use RPi 4 now because it's easier and it works perfect.

Kind greetings from a wet Sweden,

wrt to that / fwiw

iv found it is possible to borrow from other distro ( initially suse ( but their build lack chain-loader grub cmd ) , & afair iv found builds from other distros )
uboot-efi ldr -> grub2efi
built for pi/arm64

copy the files to the pi firmware /boot partition

then create extra partitions and grub2 menu-config for testing different versions or even other os's 'root-fs' ( requires pointing the menu entry at each distro or viersion's partition uuid or label )
 

and use this to boot/test alternative config's or distros from their own partition

though this is possible to do with just TC and some kernel/cmdline options (and renaming core.gz and kernel for each version )
it is imho easier to reason about ( especially while testing alt config ) with separate partitions

PS The only thing I have to worry about is the size of the backup. It's already about 74.5MB DS

best way around this imho is to
create a "static" home partition
and disable backup of ~/

Hello mocore!

Thanks for your interest. The thing is that I have the contents of a database and a python project in /home/tc that has to be there. So I need to backup that even if it gets a little big.

Kind regards,meo

startup script adjusted for Xorg-3d in the piCore64 17.x repo - it seems to work for me now on an RPi5

Hi Juanito
Just an observation, but out of curiosity, I took a look at that startup script:

Code: [Select]

#!/bin/sh

REVISION=$(awk -F: '/^Revision/ { print $2 }' /proc/cpuinfo | sed 's/ //g')
REVISION=${REVISION: -6}
case ${REVISION:2:1} in
    3|4) #BCM2711 and BCM2712 CPU"
        break
    ;;
    0|1|2) #BCM2835, BCM2836 and BCM2837 CPUS, all early VC4 Graphics
        cp /usr/local/share/Xorg-3d/files/20-noglamor.conf /usr/local/share/X11/xorg.conf.d
    ;;
    *) #Unknown CPU
        break
    ;;
esac

case ${REVISION:2:1} in
    4) #BCM2712 CPU"
        cp /usr/local/share/Xorg-3d/files/99-vc4.conf /usr/local/share/X11/xorg.conf.d
    ;;
    0|1|2|3) #BCM2835, BCM2836, BCM2837 and BCM2711 CPUS
        break
    ;;
    *) #Unknown CPU
        break
    ;;
esac
Maybe I'm missing something, but it looks like this would accomplish the
same thing without creating a second  case  statement:

Code: [Select]

#!/bin/sh

REVISION=$(awk -F: '/^Revision/ { print $2 }' /proc/cpuinfo | sed 's/ //g')
REVISION=${REVISION: -6}
case ${REVISION:2:1} in
    4) #BCM2712 CPU"
        cp /usr/local/share/Xorg-3d/files/99-vc4.conf /usr/local/share/X11/xorg.conf.d
    ;;
    3) #BCM2711 CPU"
        break
    ;;
    0|1|2) #BCM2835, BCM2836 and BCM2837 CPUS, all early VC4 Graphics
        cp /usr/local/share/Xorg-3d/files/20-noglamor.conf /usr/local/share/X11/xorg.conf.d
    ;;
    *) #Unknown CPU
        break
    ;;
esac

You're not missing anything - I'm hopeless at this kind of thing, Xorg-3d re-posted with updated startup script

Hello Juanito and Rich!

I made a new install of piCore64 v17 beta 2. It works very well. The only thing I had to do was to make sure that Xorg-3d was available so I chose, download only, and now it works as a charm.Thanks for your diligent work!

Kind Regards,

Hi everybody!

I am working with the sound and video on my Raspberrt Pi 5 using piCore64 v17beta2. I got an error trying to download mpv that said: "WARNING: 50 of 50 computed checksums did NOT match
Error on libavdevice.tcz". So apparently there is something wrong there.

Kind greetings,
meo

[Juanito]

I just tried the command "tce-load -w mpv" and everything downloaded without problems.

Perhaps something got corrupted during your download, you could try deleting libavdevice.tcz* and re-starting the download.

[Juanito]

mpv updated to use the latest version of the ffmpeg7 libraries

[meo]

Hi Juanito!

You were right the file was corrupted. Downloading again was a breeze!

Kind Greetings,
meo

Any reason to not move this to release?
