Hello, I have try to build kernel for raspi4 from upstream (5.5-rc3). Kernel boot but can't find the SD Card, so there is no partition, no root-fs and end up in initramfs/busybox. Log of serial console is attached. I have used U-boot and dtb from ubuntu image. My dtb build during kernel build is a half size of the ubuntu one and doesn't work. the custom build kernel works on rpi3 out of the box. best regards p.s. i build it as deb package
