Re: Firefox crashes all the time on the RaspBerry Pi Zero 2W

I've installed this image file on sd card :

FreeBSD-13.5-STABLE-arm-armv6-RPI-B-20250403-f8cd0c8e20b0-259236.img.xz

and I tried to boot my Raspberry Pi Zero 2W. I've got the rainbow screen.
At this point I tried to swap some dtb files :

marietto# pkg search rpi-firmware

rpi-firmware-1.20230405.g20230405 Firmware for RaspberryPi Single Board
Computer

marietto# pkg install rpi-firmware

New packages to be INSTALLED:
rpi-firmware: 1.20230405.g20230405

marietto# cd /usr/local/share/rpi-firmware/

marietto# ls

marietto# cp bcm2708-rpi-zero.dtb /mnt/da0s1/bcm2708-rpi-zero.dtb

also tried :

marietto# cp bcm2708-rpi-zero-w.dtb /mnt/da0s1/bcm2708-rpi-zero-2-w.dtb

and :

marietto# cp bcm2708-rpi-b.dtb /mnt/da0s1/bcm2708-rpi-zero-2-w.dtb

No one worked. There isn't any dtb file that can boot this image file :

FreeBSD-13.5-STABLE-arm-armv6-RPI-B-20250403-f8cd0c8e20b0-259236.img.xz

on the raspi zero 2 W....
