Pi Compute Module 5, kernel panic. #1394

Are you testing with the cm5 plugged into the IO Board? It looks like the official Raspberry Pi OS images are shipping with: I'll try to reproduce the panic you show, but while also using these extra sets of .dtb files. I guess the |

I'm not sure what's wrong. I can't even get console uart out on my builds. I tried to go with a newer kernel than your diff --git a/conf/machine/include/rpi-base.inc b/conf/machine/include/rpi-base.inc

Yes
I'm working with one of the "fat ones", tbh not sure on the capacity :/
To get earlycon uart out on the GPIO you need to add After creating this issue I've also tried with an image created with buildroot, yielding the same results. |

I saw a similar kernel panic like After adding |
|
@gokamura that indeed did fix it for me! It's booting now. |

Yes, I think that was my problem as well (adding bcm2712d0.dtb0 to the overlays). Not sure why I couldn't get UART console on boot earlier. My config.txt is pretty messy/nonsensical. For posterity: root@raspberrypi5:~# dmesg | head

Description
The kernel panics on a CM5
Steps to reproduce the issue:
config.txt:
cmdline.txt:
dwc_otg.lpm_enable=0 root=/dev/mmcblk0p2 rootfstype=ext4 rootwait net.ifnames=0 console=ttyAMA0,115200 earlycon=pl011,0x1c00030000,115200n8(not sure if ttyAMA0 is correct, it panics regardless of that being set)3. Boot and observe the kernel panic.
Additional details (revisions used, host distro, etc.):
I've tried adding the CM5 overlays to the raspberry5.conf & include, however this doesn't fix the panic:
