Raspberry Pi 5 - not booting

[mdevaev]

Hello. I am trying to run Alarm on Pi 5. I have compiled the updated raspberrypi-bootloader and raspberrypi-firmware from the last commit of [url]https://github.com/raspberrypi/firmware[/url], Pi 5 support has already been added there. It is also stated that 32 bit Raspberry OS runs on Pi 5. However, I came across the fact that Pi 5 does not booting: [url]https://i.imgur.com/AKKnFLU.jpg[/url]

Let's debug this together, and when the hardware goes on sale, Alarm will already work on it

To my knowledge, no one has this hardware yet for testing so you on out on your own. First question is why are you using armv7h with this hardware? Which kernel are you using? I hope it's linux-rpi.

I concur with @graysky. I see no linux/arch/arm/configs/bcm2712_defconfig to compile a kernel on 32bit; the only one I see is linux/arch/arm64/configs/bcm2712_defconfig. The pi5 is not supposed to run on on a pi4 kernel. On the 64bit kernel the pi5 kernel is named kernel_2712.img and that is what it's firmware is supposed to look for at boot.

I have not received my pi5 yet so I am probably the last person to give advice. lol I have done some prep work based on things I have picked up online. I have a 64bit kernel built and an image. You can look at my PKGBUILD and tweak it to fit with ARCH-ARM ways if you want to use it as a base. I have made this kernel to co-exist in the same image as the pi4's/pi3's is the reason for some weirdness in the PKGBUILD. If it is the only device in your image then the /boot/overlays directory needs to be added.

Yes, it is. I use armv7 because my entire environment is 32 bit (I'm a PiKVM developer)

It seems you're right. I checked Raspberry OS. It boots aarch64 kernel even on armv7h OS/environment.

So, how we'll deal with it? @graysky Do you think a separate linux-rpi5 package is needed for Alarm?

A look at the new PiOS 64bit image in /boot. What else that has my attention is that I have not seen before RPi generating an initramfs before. I am going to see today what is inside of both of them.

Good day,
was there any progress made? Got my Pi 5 today and would like to start using it.

Use aarch64 with linux-rpi on any other compatible Pi (3, 4 etc). Update the image. Put the uSD card in the Pi5 and it should just work.

[solskogen]

or use pacstrap to a USB device. That also works!

How exactly do I update the image? I actually cloned my SD card, and did a "sudo pacman -Syu" on my RPi 4.
However boot partition is still missing "bcm2712-rpi-5-b.dtb" and probably more.

Did you install linux-rpi on the image?

[code]
% pacman -Ql linux-rpi | grep rpi-5
linux-rpi /boot/bcm2712-rpi-5-b.dtb
