Latest 6.6 does not compile native for Pi Zero 2 W, or boot up when cross-compiled #6604

Add or modify the following line, if you miss this you’d have to connect sd card and edit file in root folder, your pi will keep restarting otherwise: kernel=kernel8.img add in /boot/config.txt |

bcm2711_defconfig is for Rpi 4 and CM4. Please try bcmrpi3_defconfig |

dr-drone: Sorry, I don't understand what line you are talking about adding or modifying and what the modification should be. lategoodbye: Trying to build arch64 for the rpi zero 2 w, according to: https://www.raspberrypi.com/documentation/computers/linux_kernel.html I guess I am missing a step in: https://www.raspberrypi.com/documentation/computers/linux_kernel.html |

@lategoodbye bcm2711_defconfig is suitable for use on any 64-bit-capable Pi. bcmrpi3_defconfig is an old, b community-contributed defconfig which should probably be deleted. |

@scottea12 Is it possible you missed the * before .dtb for the cp commands or is it just a copy & paste error? |

@popcornmix - Originally I was trying to build natively and tried both 1 and 6 compilers with the same lockup result (by lockup, the ssh connection disconnects, so I cannot tell if it is a lock up or just a disconnect). Because of that I switched to cross-compiling on an i9 machine with 64g ram. It completes the compile fine that way. @lategoodbye - always a good thing to check. I am mainly copy and pasting from the build document. The commands are correct and are copying all dtb files. However, this made me look closer and figured out that I missed the root copy update: Thank you all for your efforts to help me figure out my own stupid mistake. |
Describe the bug
When trying to compile the 6.6 default kernel nativity on pi zero 2 w, the ssh session locks up, so not sure what if it is just the ssh connection that disconnects or that the build actually locks up. When cross-compiling and installed on the drive, the pi does not boot up. Installing the 6.6.51 (download from the rpi imager, it works just fine. I am not an expert, so don't have many details.
Steps to reproduce the behaviour
Cross-compile on ubuntu, copy to ssd... doesn't boot.
Steps I followed:
sudo apt install git bc bison flex libssl-dev make libc6-dev libncurses5-dev crossbuild-essential-arm64
git clone --depth=1 --branch=rpi-6.6.y https://github.com/raspberrypi/linux
6.6.51+rpt-rpi-v8
cd linux
KERNEL=kernel8
CONFIG_LOCALVERSION="-v8-my-kernel"
make ARCH=arm64 CROSS_COMPILE=aarch64-linux-gnu- bcm2711_defconfig
make -j6 ARCH=arm64 CROSS_COMPILE=aarch64-linux-gnu- Image modules dtbs
install kernel (from vm machine):
sudo cp /media/pi/bootfs/$KERNEL.img /media/pi/bootfs/$KERNEL-backup.img
sudo cp arch/arm64/boot/Image /media/pi/bootfs/$KERNEL.img
sudo cp arch/arm64/boot/dts/broadcom/.dtb /media/pi/bootfs/
sudo cp arch/arm64/boot/dts/overlays/.dtb* /media/pi/bootfs/overlays/
sudo cp arch/arm64/boot/dts/overlays/README /media/pi/bootfs/overlays/
