R35.2.1 Xavier NX Kernel Panic on boot (CPU:0, Error: cbb-noc@2300000, irq=15)

Currently there are obvious edid read and hdmi_enable logs, after you disable bootloader status, you won’t see them.

Hi
I used dtb file as pointed on /boot/extlinux/extlinux.conf

LABEL primary
MENU LABEL primary kernel
LINUX /boot/Image
FDT /boot/dtb/kernel_tegra194-p3668-0001-p3509-0000.dtb
INITRD /boot/initrd
APPEND ${cbootargs} root=/dev/mmcblk0p1 rw rootwait rootfstype=ext4 console=ttyTCU0,115200n8 console=tty0 fbcon=map:0 net.ifnames=0

and added bootloader-status = “disabled” to part related display - display@15200000, display@15210000, display@15220000, display@15230000.
after I did all, I did to full flash or change dtb file in /boot/dtb/.
but there is no change on the log. I saw again edid read and hdmi_enable logs.
How could I do this - flash the bootloader dtb partition ?

You need to put your new dtb on the host machine Linux_for_Tegra/kernel/dtb and do full reflash…

Read the flash log to make sure your dtb really gets flashed to the board.
