I am getting error don't know the reason,
It's showing : start4x.elf: is not compatible, this board requires newer software
I've checked firmware version it's up to date. 11th jan 2023 release, Raspberry pi 4 version is Rev1.5 8GB RAM.
Ubuntu 20.4 is required as it supports ROS noetic and later version of ubuntu don't support ROS1.
Also I've tried booting on Pi 3B+ it boots without any error.
please help me out of this.
