Raspberry Pi 4B does not boot Debian Testing

[knuxyl]

I have installed to an sd card and a USB drive and neither will boot. Both boot to the rainbow screen and will not continue. Power supply is more than adequate, used different storage medias, tried both hdmi ports, etc. I cannot provide logs because no logs are being generated. I don't even know if it is loading anything from the media, I'm not too familiar with rpi boot process. Ethernet does not request IP address either, so I know that it's not the hdmi not working, it's not even booting the kernel. I had this problem like 6 months ago with these builds but I just thought my sd card was bad or something so I didn't try any further. Today I spent a considerable amount of time working on this and have concluded it is these images, not my storage media. Raspbian installs and boots just fine.

I have also encountered this when trying the images in recent months, and not known how to report it. I've usually reverted to using the Debian-provided Tested Images as a fallback.

Do you have any logs?

[knuxyl]

No, it does not generate any logs because the kernel is not loading. I checked and uboot isnt generating any logs either.

Looking through my notes, I discovered my first experience with this was back in May. As noted in the original report, it seems to simply freeze at the RPi "rainbow square" screen.

Im still having this problem with rpi4 - only rainbow screen.

Since its the boot file it must effect all the other files as well.

Perhaps this is a noob question but I have tried the rpi4 uefi files from pftf which works, but I’m having trouble booting Debian os.

I found this when I searched after a complete Debian vanilla image for raspberry pi - is this correct ?

I have just tried latest debian testing again on an sdcard and it still won't boot. I get a rainbow screen. I updated the eeprom to 2013 01 and still doesn't work. UART isn't putting anything out either.

I also tried creating an extlinux.conf in /boot/extlinux/ for u-boot but that didn't work. I thought maybe uboot just wasn't booting so I built it from master and still the same results. I am convinced uboot isn't booting and I don't know why. I read a tutorial on booting u-boot on this board and it's set up the same way as what these scripts do.

I renamed uboot to kernel8.img as per official docs and removed the kernel line from config.txt and still nothing.
