  • Linux kernel supports Raspberry Pi 4

    From Doug Laidlaw@2:250/1 to All on Tue Jun 15 19:18:35 2021
    Version 4 is the current release of software for the Pi4. The Pi runs a system-on-a-chip with an ARM kernel. A recent news release says that
    from Version 5.5, the Linux kernel supports the Pi4, the Pi 400 and a
    lot of other new hardware. I was surprised to learn that the Microsoft Surface has an ARM processor. The architecture, which I had thought was
    now a historical curiosity, seems to be making a strong comeback.
    Mageia are developing an ARM version of the distro, but a note says that
    it won't work on a Raspberry Pi.

    I'm running Mageia 8 on a Raspberry Pi 4b.

    The install images are on the mirrors, for example ... http://mirror.math.princeton.edu/pub/mageia/distrib/8/aarch64/install/images/

    Running kde4/plasma everything is working except sound over hdmi.

    Interesting. I assume that your HDMI cable carries a sound channel. My monitor has only a mini socket for sound input, and the Pi400 has no
    sound output available, except via USB. I don't know about Bluetooth
    for sound; I had some USB speakers lying around. For analog sound, I
    have to uncomment a line in the config.txt file every time. In the 400,
    that setting can be accessed from the desktop.

    It's apparently working in the older rpi systems, but not the rpi 4b.

    It works in Raspbian os, but not in Mageia 8, so it's not a hardware problem. As arm support in Mageia is considered experimental, it's not a high priority.

    This the hazard of clinging to interest only in the topics
    that concern you. The Raspberry Pi has been of great interest
    to project builders and is ubiquitous in maker circles. Linux Pro
    Magazine here in the USA which is Linux Magazine overseas has
    projects either continuing or new in every issue and before Covid+19
    there was a magazine devoted to it.

    Just as a postscript, the article was written a year ago, when Kernel
    5.5 had just been released and was not yet in any major distribution.
    Mageia 8 currently uses Kernel 5.10.43.

    What is the difference between aarch64 and ARMV7, and which one do I
    need? It is a whole new vocabulary. The download site says that
    officially, there is no installer, just a basket of packages.

    The armv7 label is used for 32 bit arm cpu systems, aka aarch32. Having a 64 bit
    arm cpu makes the rpi 4b an aarch64 system.

    The arm devices do not support booting from anything other then the files in a regular partition. No iso boot support. The Mageia images were created based on the
    live iso images. Just copy the image to the sd card, and resize the partition and filesystem if desired. On first boot, it asks for the user id, network setup,
    etc. Once the network is working rpmdrake can be used to install any regular Mageia
    package.
