Thanks for this tutorial! I’m trying to get a basic build with Mender on a Pi 4. I originally tried using mender-convert, but I couldn’t get it working. Yocto seems like a better move overall anyway, so I’m trying my luck here instead. However, I can’t seem to get the Yocto build to work. I get a .…

Hi @Vladimir , I think I have found and fixed it! Care to give the current HEAD of [`meta-mender-community]( GitHub - mendersoftware/meta-mender-community: Community supported integration layers for Mender on various boards ), branch `scarthgap` a spin for Raspberry Pi 4 32bit. Greetz, Josef

Hi @nickfh7 , Thanks for the heads up! I’ve looked into it and can reproduce the booting bug, but don’t have the solution yet. Concerning the other points: the machine: raspberrypi4 line in kas/raspberrypi4-64.yml is indeed wrong, fixed already. the secondary (inactive) partition is empty by defa…

Hey @TheYoctoJester , Just checking to see if you’ve had any luck finding a fix. I found an issue with psplash-systemd.service, and disabling it in a bbappend allows the 64-bit version to boot. Any thoughts here? Could something else still be wrong? I’m not entirely sure why this happened, but I saw…

Hi @nickfh7 , On the variety of topics: the boot bug on 32bit raspberrypi4 I have not identified yet. Its a bit obscure because the exact same u-boot configuration works on kirkstone :frowning: the root login being disabled, that is expected. As a security best practice, it is disabled by default …

Hi @nickfh7 , to expand a bit: I just built core-image-weston for raspberrypi4-64, and while it has some rough edges (like psplash blocking boot for some time) and it boots extremely slow (multiple minutes!), it otherwise seems to be working fine. Some additions I needed to local.conf: LICENSE_FLA…

Thanks again for the responses! I have a version of my system working based on meta-raspberry-pi’s kas file, and I missed the debug-tweaks addition that enable root login. Going to the Mender version, I thought I was experiencing this issue . Looks like this isn’t the case though, so that’s good. De…

Hello @TheYoctoJester . I have yocto dunfell (3.0) project for RPi 4B with mender, and it works awesome. But I decided to upgrade to scarthgap (5.0) and followed this manual ( Raspberry Pi 4 Model B - Yocto 5.0 "scarthgap" and later ) to create core-image-minimal image with no customization at all. Im…

Hi @Vladimir , Interesting catch concerning the DRAM size. I have also seen some weird behavior, and in my tests it seems to be limited to the 32bit version only. Can you confirm that this is the case here too? And give the 64bit builds a test spin? Greetz, Josef

I’ve created raspberrypi4-64 image and I got the next lines during first boot: U-Boot 2024.04 (Apr 02 2024 - 10:58:58 +0000) DRAM: 948 MiB (effective 7.9 GiB) RPI 4 Model B (0xd03114) Core: 211 devices, 16 uclasses, devicetree: board MMC: mmcnr@7e300000: 1, mmc@7e340000: 0 Loading Environment …

Hi @Vladimir , The initial CRC error is actually not an error, the wording is unfortunate. The meaning is “no environment found, using the default one”. And that’s absolutely fine and intended, as the default environment is explicitly fine for operation (without Mender integration), and on first sta…

Similar behaviour is observed with vanilla u-boot (without mender support). It looks like u-boot issue, not related to mender.
