RPi 4B boot

Hi.

I bought a RPi 4 - 4GB and also 64 Gib microsd for storage and system.

I used https://info.armtixlinux.org/raspberrypi4.html for guide and I did everything (I chose u-boot path).

This is my partition table (in MBR/dos):
Code: [Select]
sdc      8:32   1  59.5G  0 disk
├─sdc1   8:33   1   512M  0 part /mnt/Removable_2
└─sdc2   8:34   1    59G  0 part /mnt/Removable

cfdisk result:
Code: [Select]
                                                            Disk: /dev/sdc
                                        Size: 59.52 GiB, 63908610048 bytes, 124821504 sectors

I also installed https://github.com/raspberrypi/firmware/releases/tag/1.20240529 for firmware.

But my RPi doesn't boot and log is in attachment. It says "Firmware not found". I can't understand because I copied all firmware files into /boot.

I'm a little noob with ARM devices.

I don't see any config.txt in your /boot. RPi requires it to choose whisch kernel (or uboot) to run

I still need a config.txt for u-boot? That guide doesn't mention it for u-boot. What will be my config.txt for u-boot way?
Something like this?
Code: [Select]
enable_uart=1
arm_64bit=1
kernel=/Image
initramfs /initramfs-linux.uimg followkernel
device-tree=/dtbs/broadcom/bcm2711-rpi-4-b.dtb

Looks like my firmware aren't present there (0 bytes size), I copied them again. Also I set config.txt file and cmdline.txt file and Now I see one of the most weird things in my life :/ A picture of color range? See attachment.

The u-boot instruction suggests you install u-boot package from ALARM repos. IIRC it should contain the appropriate config.txt (the one you have corresponds to the one which directly boots kernel) and u-boot binray as kernel8.img.
In general, it is good to have a UART cable for debug purposes since usually early boot errors are only shown there.

Looks like the armtix guide is for someone who is actually familiar with ARM systems concept. I got http://ca.us.mirror.archlinuxarm.org/aarch64/alarm/uboot-raspberrypi-2024.04-2-aarch64.pkg.tar.xz package and copied all of it contents into my /boot and then I did run ./mkscr to make sure everything is ok. Now I have a u-boot showing on screen but stuck at "Starting Kernel..." part. I missed something again?
I'm going to read https://archlinuxarm.org/platforms/armv8/broadcom/raspberry-pi-4 for some instructions.

I fixed boot.cmd with Armtix Linux guide instead of Arch linux stock boot.cmd (It was replaced by u-boot package from ALARM) and now I have a working RPi 4B :)

I also updated system by pacman -Syu and I forgot to generate u-boot initramfs, I connected it to my computer once again and fixed it. Is there any package to automate this process?

@phoenix_king_rus Thanks for your advices.

WDYM by u-boot initramfs?

I mean "mkimage -A arm -T ramdisk -d initramfs-linux.img initramfs-linux.uimg"
