  • Swap rpi3 to rpi4 with same SD card

    From Jack@3:770/3 to All on Thu Jul 15 13:47:35 2021
    Hello,

    I just got a rpi4, ans seen that I have too many thing installed on my
    rpi3, I want to take the sd card from the rpi3 and put it on the rpi4.

    I'm following this tutorial <https://seven1m.sdf.org/tutorials/upgrade_raspberry_pi_3_to_4_with_same_sd_card.html>

    but I have a problem with step5: when I try to reinstall the bootloader,
    I get his error:

    pi@raspberrypi:~ $ sudo apt install --reinstall raspberrypi-bootloader raspberrypi-kernel
    Reading package lists... Done
    Building dependency tree... Done
    Reading state information... Done
    Reinstallation of raspberrypi-bootloader is not possible, it cannot be downloaded.
    Reinstallation of raspberrypi-kernel is not possible, it cannot be
    downloaded.

    Any ideas how to solve it?

    Thanks bye
    Jack

    IIRC, all current RPi software versions contain the software needed to
    boot and run on any RPi, so how long is it since you last updated the
    software on that SD card?

    IOW, if you haven't done so recently, update that card image on the RPi3
    and try again, but be aware that the /dev/mmcblk0p1 boot partition, which
    is mounted on /boot, used to be very small (50MB or less), so if you
    haven't resized it recently, you should copy the card contents to a new,
    bigger SD card with /dev/mmcblk0p1 increased to at least 500MB - I'm
    currently using 16GB cards with a 1GB boot partition.

    yes, I had to resize the /boot partition (now is 300MB).
    In the meantime I found the issue.
    For some reason I didn't have the raspi.list in /etc/apt/sources.list.d/ (probably beccause the isnallation is very old), so apt didn't get the repository
    deb http://archive.raspberrypi.org/debian/ buster main ui

    where raspberrypi-bootloader and so on are.

    Added it, and after and apt update and full-upgrade later, the rpi4
    booted up correctly.

    Bye Jack
